eusociality

Eusociality

Business / By /

Eusociality is a specialized form of social organization observed in certain animal species, characterized by cooperative and organized behavior within colonies or communities. It involves a division of labor, reproductive castes, overlapping generations, and cooperative care of offspring. Eusociality is found primarily in insects, such as ants, bees, and termites, but can also occur in some species of mammals and crustaceans.

Key Features of Eusocial Insects:

  1. Reproductive Division of Labor:
    • Eusocial insect colonies typically consist of a single reproductive queen or a small number of reproductive individuals responsible for producing offspring.
    • Non-reproductive workers, often sterile females, perform various tasks such as foraging, nest maintenance, brood care, and defense, supporting the reproductive individuals in the colony.
  2. Overlap of Generations:
    • Eusocial colonies exhibit overlapping generations, with multiple age cohorts of individuals coexisting within the colony.
    • Older individuals, such as the queen and experienced workers, contribute to colony longevity and stability, while younger individuals replenish the workforce and assume specialized roles as they mature.
  3. Cooperative Brood Care:
    • Eusocial insects engage in cooperative brood care, with workers collectively tending to the eggs, larvae, and pupae produced by the reproductive individuals.
    • Workers regulate temperature, humidity, and food provisioning within the nest to ensure the health and development of the brood, thereby contributing to the reproductive success of the colony.
  4. Division of Labor:
    • Eusocial colonies exhibit a division of labor, where individuals specialize in specific tasks based on age, morphology, or behavioral tendencies.
    • Task allocation may be flexible, with individuals transitioning between roles in response to colony needs, environmental conditions, or internal cues such as pheromones.

Evolutionary Origins of Eusociality:

  1. Kin Selection Theory:
    • Kin selection theory proposes that eusociality evolves through the differential reproduction of genes shared between relatives, particularly close kin.
    • By assisting reproductive relatives, individuals can enhance the inclusive fitness of their shared genes, even at the expense of their own direct reproduction.
  2. Haplodiploidy Hypothesis:
    • The haplodiploidy hypothesis suggests that the genetic relatedness among colony members in some eusocial insects, such as Hymenoptera (ants, bees, and wasps), facilitates the evolution of eusociality.
    • In haplodiploid species, females develop from fertilized eggs (diploid) and males develop from unfertilized eggs (haploid), leading to higher relatedness among sisters than between mothers and offspring or among non-sibling individuals.
  3. Environmental Factors:
    • Environmental factors, such as resource availability, predation pressure, and habitat stability, may also influence the evolution of eusociality by favoring cooperative strategies that enhance colony survival and reproductive success.
    • Eusociality is more likely to evolve in environments where individuals benefit from aggregating together and exploiting shared resources or defensive mechanisms.

Adaptive Benefits of Eusociality:

  1. Efficient Resource Utilization:
    • Eusocial colonies can efficiently exploit resources by dividing labor among specialized individuals and coordinating collective foraging, food storage, and resource allocation strategies.
    • Division of labor allows colonies to exploit a wide range of ecological niches and respond flexibly to fluctuating resource availability.
  2. Effective Defense and Predator Deterrence:
    • Cooperative defense behaviors, such as nest guarding, alarm signaling, and coordinated aggression, enhance the ability of eusocial colonies to deter predators and repel intruders.
    • Large numbers of workers can overwhelm predators through sheer numbers or inflict defensive injuries to protect the colony.
  3. Climate Regulation and Nest Construction:
    • Eusocial insects exhibit sophisticated nest-building behaviors and architectural structures that provide thermal insulation, ventilation, and protection from environmental extremes.
    • By regulating nest microclimates, colonies can optimize brood development, fungal cultivation, and other critical activities essential for colony survival.

Challenges and Trade-Offs in Eusociality:

  1. Costs of Altruism:
    • Eusociality imposes costs on individual fitness, particularly for non-reproductive workers that forego direct reproduction to support the colony.
    • Workers may experience increased mortality risks, reduced reproductive opportunities, and energetic costs associated with task performance and colony maintenance.
  2. Conflict and Cooperation:
    • Eusocial colonies must navigate conflicts of interest and maintain cooperation among colony members, balancing individual needs with collective benefits.
    • Intraspecific competition, reproductive skew, and conflicts over resource allocation or reproductive monopolization can challenge colony cohesion and stability.
  3. Environmental Pressures:
    • Eusocial colonies face threats from environmental changes, habitat disturbance, pathogens, parasites, and competition with other organisms.
    • Colonies must adapt to changing environmental conditions, disperse to new habitats, or develop resilience strategies to mitigate the impacts of environmental stressors.

Conclusion:

Eusociality represents a remarkable example of cooperative behavior and social organization in the animal kingdom, with eusocial insects exhibiting sophisticated strategies for survival, reproduction, and resource utilization. By understanding the evolutionary origins, adaptive benefits, and ecological dynamics of eusociality, researchers can gain insights into the mechanisms underlying cooperative behavior, altruism, and social complexity in diverse biological systems. Recognizing the challenges and trade-offs associated with eusociality is essential for elucidating the factors shaping social evolution and ecosystem dynamics in both natural and human-modified environments.

AspectDescription
Key Elements1. Reproductive Castes: Eusocial colonies typically consist of different castes with distinct roles, including reproductive individuals (queens and kings) and non-reproductive workers. 2. Cooperative Care: Members of eusocial colonies work together to care for and protect offspring, maintain the colony, and forage for food. 3. Overlap of Generations: Multiple generations coexist within the colony, ensuring continuity and stability. 4. Division of Labor: Tasks are divided among colony members, with each individual specializing in specific roles or functions.
Common ApplicationEusociality is primarily observed in social insects, where it enhances survival, resource utilization, and reproductive success. Understanding eusociality is important in the fields of biology, ecology, and evolutionary science.
ExampleIn a eusocial ant colony, the queen is responsible for laying eggs, while worker ants perform tasks such as foraging for food, caring for the queen’s offspring, and defending the colony. This division of labor and cooperative behavior characterizes eusociality.
ImportanceEusociality is a remarkable biological phenomenon that has significant ecological and evolutionary implications. It offers insights into the evolution of social behavior, cooperation, and the ecological success of eusocial species.
Case StudyImplicationAnalysisExample
Honeybee ColoniesEfficient resource utilization and pollination.Honeybee colonies are eusocial and play a crucial role in pollinating flowering plants. The division of labor among worker bees, the protection of the queen, and the efficient collection of nectar and pollen contribute to the ecological importance of honeybee colonies.A study on honeybee colonies reveals how the eusocial structure enables them to collect nectar and pollen efficiently, distribute resources among colony members, and provide pollination services critical for agriculture and biodiversity.
Ant Colony CompetitionCompetitive advantage in foraging and defense.Eusocial ant colonies often outcompete solitary or less social species. The coordinated efforts of worker ants in foraging, defending the colony, and tending to the queen’s offspring give eusocial ant colonies a competitive edge in resource acquisition and survival.Researchers compare the foraging efficiency and survival rates of eusocial ant colonies to those of non-eusocial ant species. They find that eusocial colonies have a higher success rate in resource acquisition and colony defense, leading to a competitive advantage.
Termites and Wood DecompositionEcosystem roles and nutrient cycling.Eusocial termite colonies play a vital role in breaking down wood and plant material, contributing to nutrient cycling in ecosystems. The cooperative behavior of termites in digesting cellulose-rich materials benefits both termites and the environment.A study in a tropical forest ecosystem explores the impact of eusocial termite colonies on wood decomposition. Researchers find that termite colonies significantly accelerate the breakdown of wood, releasing nutrients into the soil and benefiting the overall ecosystem.
Naked Mole Rat SocietiesInsights into social structure and longevity.Naked mole rats are eusocial mammals known for their longevity and resistance to cancer. Studying their eusocial societies provides insights into the relationship between social behavior and life span, as well as the mechanisms underlying cancer resistance.Researchers investigate the social structure and cooperative behavior of naked mole rat colonies. They find that eusociality contributes to their extended life span and resistance to age-related diseases, including cancer, shedding light on potential applications in human health.
Human Cooperation and AltruismComparative studies on social behavior.Understanding eusociality in other species, such as insects and naked mole rats, can offer valuable insights into the evolution of cooperation, altruism, and social behavior in humans. Comparative studies provide a broader perspective on the origins and mechanisms of sociality.Researchers examine the parallels between eusociality in non-human species and cooperative behavior in human societies. By comparing the genetic, ecological, and behavioral factors influencing cooperation, they gain a deeper understanding of the evolution of social behavior.

Connected Thinking Frameworks

Convergent vs. Divergent Thinking

convergent-vs-divergent-thinking
Convergent thinking occurs when the solution to a problem can be found by applying established rules and logical reasoning. Whereas divergent thinking is an unstructured problem-solving method where participants are encouraged to develop many innovative ideas or solutions to a given problem. Where convergent thinking might work for larger, mature organizations where divergent thinking is more suited for startups and innovative companies.

Critical Thinking

critical-thinking
Critical thinking involves analyzing observations, facts, evidence, and arguments to form a judgment about what someone reads, hears, says, or writes.

Biases

biases
The concept of cognitive biases was introduced and popularized by the work of Amos Tversky and Daniel Kahneman in 1972. Biases are seen as systematic errors and flaws that make humans deviate from the standards of rationality, thus making us inept at making good decisions under uncertainty.

Second-Order Thinking

second-order-thinking
Second-order thinking is a means of assessing the implications of our decisions by considering future consequences. Second-order thinking is a mental model that considers all future possibilities. It encourages individuals to think outside of the box so that they can prepare for every and eventuality. It also discourages the tendency for individuals to default to the most obvious choice.

Lateral Thinking

lateral-thinking
Lateral thinking is a business strategy that involves approaching a problem from a different direction. The strategy attempts to remove traditionally formulaic and routine approaches to problem-solving by advocating creative thinking, therefore finding unconventional ways to solve a known problem. This sort of non-linear approach to problem-solving, can at times, create a big impact.

Bounded Rationality

bounded-rationality
Bounded rationality is a concept attributed to Herbert Simon, an economist and political scientist interested in decision-making and how we make decisions in the real world. In fact, he believed that rather than optimizing (which was the mainstream view in the past decades) humans follow what he called satisficing.

Dunning-Kruger Effect

dunning-kruger-effect
The Dunning-Kruger effect describes a cognitive bias where people with low ability in a task overestimate their ability to perform that task well. Consumers or businesses that do not possess the requisite knowledge make bad decisions. What’s more, knowledge gaps prevent the person or business from seeing their mistakes.

Occam’s Razor

occams-razor
Occam’s Razor states that one should not increase (beyond reason) the number of entities required to explain anything. All things being equal, the simplest solution is often the best one. The principle is attributed to 14th-century English theologian William of Ockham.

Lindy Effect

lindy-effect
The Lindy Effect is a theory about the ageing of non-perishable things, like technology or ideas. Popularized by author Nicholas Nassim Taleb, the Lindy Effect states that non-perishable things like technology age – linearly – in reverse. Therefore, the older an idea or a technology, the same will be its life expectancy.

Antifragility

antifragility
Antifragility was first coined as a term by author, and options trader Nassim Nicholas Taleb. Antifragility is a characteristic of systems that thrive as a result of stressors, volatility, and randomness. Therefore, Antifragile is the opposite of fragile. Where a fragile thing breaks up to volatility; a robust thing resists volatility. An antifragile thing gets stronger from volatility (provided the level of stressors and randomness doesn’t pass a certain threshold).

Ergodicity

ergodicity
Ergodicity is one of the most important concepts in statistics. Ergodicity is a mathematical concept suggesting that a point of a moving system will eventually visit all parts of the space the system moves in. On the opposite side, non-ergodic means that a system doesn’t visit all the possible parts, as there are absorbing barriers

Systems Thinking

systems-thinking
Systems thinking is a holistic means of investigating the factors and interactions that could contribute to a potential outcome. It is about thinking non-linearly, and understanding the second-order consequences of actions and input into the system.

Vertical Thinking

vertical-thinking
Vertical thinking, on the other hand, is a problem-solving approach that favors a selective, analytical, structured, and sequential mindset. The focus of vertical thinking is to arrive at a reasoned, defined solution.

Metaphorical Thinking

metaphorical-thinking
Metaphorical thinking describes a mental process in which comparisons are made between qualities of objects usually considered to be separate classifications.  Metaphorical thinking is a mental process connecting two different universes of meaning and is the result of the mind looking for similarities.

Maslow’s Hammer

einstellung-effect
Maslow’s Hammer, otherwise known as the law of the instrument or the Einstellung effect, is a cognitive bias causing an over-reliance on a familiar tool. This can be expressed as the tendency to overuse a known tool (perhaps a hammer) to solve issues that might require a different tool. This problem is persistent in the business world where perhaps known tools or frameworks might be used in the wrong context (like business plans used as planning tools instead of only investors’ pitches).

Peter Principle

peter-principle
The Peter Principle was first described by Canadian sociologist Lawrence J. Peter in his 1969 book The Peter Principle. The Peter Principle states that people are continually promoted within an organization until they reach their level of incompetence.

Straw Man Fallacy

straw-man-fallacy
The straw man fallacy describes an argument that misrepresents an opponent’s stance to make rebuttal more convenient. The straw man fallacy is a type of informal logical fallacy, defined as a flaw in the structure of an argument that renders it invalid.

Google Effect

google-effect
The Google effect is a tendency for individuals to forget information that is readily available through search engines. During the Google effect – sometimes called digital amnesia – individuals have an excessive reliance on digital information as a form of memory recall.

Streisand Effect

streisand-effect
The Streisand Effect is a paradoxical phenomenon where the act of suppressing information to reduce visibility causes it to become more visible. In 2003, Streisand attempted to suppress aerial photographs of her Californian home by suing photographer Kenneth Adelman for an invasion of privacy. Adelman, who Streisand assumed was paparazzi, was instead taking photographs to document and study coastal erosion. In her quest for more privacy, Streisand’s efforts had the opposite effect.

Compromise Effect

compromise-effect
Single-attribute choices – such as choosing the apartment with the lowest rent – are relatively simple. However, most of the decisions consumers make are based on multiple attributes which complicate the decision-making process. The compromise effect states that a consumer is more likely to choose the middle option of a set of products over more extreme options.

Butterfly Effect

butterfly-effect
In business, the butterfly effect describes the phenomenon where the simplest actions yield the largest rewards. The butterfly effect was coined by meteorologist Edward Lorenz in 1960 and as a result, it is most often associated with weather in pop culture. Lorenz noted that the small action of a butterfly fluttering its wings had the potential to cause progressively larger actions resulting in a typhoon.

IKEA Effect

ikea-effect
The IKEA effect is a cognitive bias that describes consumers’ tendency to value something more if they have made it themselves. That is why brands often use the IKEA effect to have customizations for final products, as they help the consumer relate to it more and therefore appending to it more value.

Ringelmann Effect 

Ringelmann Effect
The Ringelmann effect describes the tendency for individuals within a group to become less productive as the group size increases.

The Overview Effect

overview-effect
The overview effect is a cognitive shift reported by some astronauts when they look back at the Earth from space. The shift occurs because of the impressive visual spectacle of the Earth and tends to be characterized by a state of awe and increased self-transcendence.

House Money Effect

house-money-effect
The house money effect was first described by researchers Richard Thaler and Eric Johnson in a 1990 study entitled Gambling with the House Money and Trying to Break Even: The Effects of Prior Outcomes on Risky Choice. The house money effect is a cognitive bias where investors take higher risks on reinvested capital than they would on an initial investment.

Heuristic

heuristic
As highlighted by German psychologist Gerd Gigerenzer in the paper “Heuristic Decision Making,” the term heuristic is of Greek origin, meaning “serving to find out or discover.” More precisely, a heuristic is a fast and accurate way to make decisions in the real world, which is driven by uncertainty.

Recognition Heuristic

recognition-heuristic
The recognition heuristic is a psychological model of judgment and decision making. It is part of a suite of simple and economical heuristics proposed by psychologists Daniel Goldstein and Gerd Gigerenzer. The recognition heuristic argues that inferences are made about an object based on whether it is recognized or not.

Representativeness Heuristic

representativeness-heuristic
The representativeness heuristic was first described by psychologists Daniel Kahneman and Amos Tversky. The representativeness heuristic judges the probability of an event according to the degree to which that event resembles a broader class. When queried, most will choose the first option because the description of John matches the stereotype we may hold for an archaeologist.

Take-The-Best Heuristic

take-the-best-heuristic
The take-the-best heuristic is a decision-making shortcut that helps an individual choose between several alternatives. The take-the-best (TTB) heuristic decides between two or more alternatives based on a single good attribute, otherwise known as a cue. In the process, less desirable attributes are ignored.

Bundling Bias

bundling-bias
The bundling bias is a cognitive bias in e-commerce where a consumer tends not to use all of the products bought as a group, or bundle. Bundling occurs when individual products or services are sold together as a bundle. Common examples are tickets and experiences. The bundling bias dictates that consumers are less likely to use each item in the bundle. This means that the value of the bundle and indeed the value of each item in the bundle is decreased.

Barnum Effect

barnum-effect
The Barnum Effect is a cognitive bias where individuals believe that generic information – which applies to most people – is specifically tailored for themselves.

Anchoring Effect

anchoring-effect
The anchoring effect describes the human tendency to rely on an initial piece of information (the “anchor”) to make subsequent judgments or decisions. Price anchoring, then, is the process of establishing a price point that customers can reference when making a buying decision.

Decoy Effect

decoy-effect
The decoy effect is a psychological phenomenon where inferior – or decoy – options influence consumer preferences. Businesses use the decoy effect to nudge potential customers toward the desired target product. The decoy effect is staged by placing a competitor product and a decoy product, which is primarily used to nudge the customer toward the target product.

Commitment Bias

commitment-bias
Commitment bias describes the tendency of an individual to remain committed to past behaviors – even if they result in undesirable outcomes. The bias is particularly pronounced when such behaviors are performed publicly. Commitment bias is also known as escalation of commitment.

First-Principles Thinking

first-principles-thinking
First-principles thinking – sometimes called reasoning from first principles – is used to reverse-engineer complex problems and encourage creativity. It involves breaking down problems into basic elements and reassembling them from the ground up. Elon Musk is among the strongest proponents of this way of thinking.

Ladder Of Inference

ladder-of-inference
The ladder of inference is a conscious or subconscious thinking process where an individual moves from a fact to a decision or action. The ladder of inference was created by academic Chris Argyris to illustrate how people form and then use mental models to make decisions.

Goodhart’s Law

goodharts-law
Goodhart’s Law is named after British monetary policy theorist and economist Charles Goodhart. Speaking at a conference in Sydney in 1975, Goodhart said that “any observed statistical regularity will tend to collapse once pressure is placed upon it for control purposes.” Goodhart’s Law states that when a measure becomes a target, it ceases to be a good measure.

Six Thinking Hats Model

six-thinking-hats-model
The Six Thinking Hats model was created by psychologist Edward de Bono in 1986, who noted that personality type was a key driver of how people approached problem-solving. For example, optimists view situations differently from pessimists. Analytical individuals may generate ideas that a more emotional person would not, and vice versa.

Mandela Effect

mandela-effect
The Mandela effect is a phenomenon where a large group of people remembers an event differently from how it occurred. The Mandela effect was first described in relation to Fiona Broome, who believed that former South African President Nelson Mandela died in prison during the 1980s. While Mandela was released from prison in 1990 and died 23 years later, Broome remembered news coverage of his death in prison and even a speech from his widow. Of course, neither event occurred in reality. But Broome was later to discover that she was not the only one with the same recollection of events.

Crowding-Out Effect

crowding-out-effect
The crowding-out effect occurs when public sector spending reduces spending in the private sector.

Bandwagon Effect

bandwagon-effect
The bandwagon effect tells us that the more a belief or idea has been adopted by more people within a group, the more the individual adoption of that idea might increase within the same group. This is the psychological effect that leads to herd mentality. What in marketing can be associated with social proof.

Moore’s Law

moores-law
Moore’s law states that the number of transistors on a microchip doubles approximately every two years. This observation was made by Intel co-founder Gordon Moore in 1965 and it become a guiding principle for the semiconductor industry and has had far-reaching implications for technology as a whole.

Disruptive Innovation

disruptive-innovation
Disruptive innovation as a term was first described by Clayton M. Christensen, an American academic and business consultant whom The Economist called “the most influential management thinker of his time.” Disruptive innovation describes the process by which a product or service takes hold at the bottom of a market and eventually displaces established competitors, products, firms, or alliances.

Value Migration

value-migration
Value migration was first described by author Adrian Slywotzky in his 1996 book Value Migration – How to Think Several Moves Ahead of the Competition. Value migration is the transferal of value-creating forces from outdated business models to something better able to satisfy consumer demands.

Bye-Now Effect

bye-now-effect
The bye-now effect describes the tendency for consumers to think of the word “buy” when they read the word “bye”. In a study that tracked diners at a name-your-own-price restaurant, each diner was asked to read one of two phrases before ordering their meal. The first phrase, “so long”, resulted in diners paying an average of $32 per meal. But when diners recited the phrase “bye bye” before ordering, the average price per meal rose to $45.

Groupthink

groupthink
Groupthink occurs when well-intentioned individuals make non-optimal or irrational decisions based on a belief that dissent is impossible or on a motivation to conform. Groupthink occurs when members of a group reach a consensus without critical reasoning or evaluation of the alternatives and their consequences.

Stereotyping

stereotyping
A stereotype is a fixed and over-generalized belief about a particular group or class of people. These beliefs are based on the false assumption that certain characteristics are common to every individual residing in that group. Many stereotypes have a long and sometimes controversial history and are a direct consequence of various political, social, or economic events. Stereotyping is the process of making assumptions about a person or group of people based on various attributes, including gender, race, religion, or physical traits.

Murphy’s Law

murphys-law
Murphy’s Law states that if anything can go wrong, it will go wrong. Murphy’s Law was named after aerospace engineer Edward A. Murphy. During his time working at Edwards Air Force Base in 1949, Murphy cursed a technician who had improperly wired an electrical component and said, “If there is any way to do it wrong, he’ll find it.”

Law of Unintended Consequences

law-of-unintended-consequences
The law of unintended consequences was first mentioned by British philosopher John Locke when writing to parliament about the unintended effects of interest rate rises. However, it was popularized in 1936 by American sociologist Robert K. Merton who looked at unexpected, unanticipated, and unintended consequences and their impact on society.

Fundamental Attribution Error

fundamental-attribution-error
Fundamental attribution error is a bias people display when judging the behavior of others. The tendency is to over-emphasize personal characteristics and under-emphasize environmental and situational factors.

Outcome Bias

outcome-bias
Outcome bias describes a tendency to evaluate a decision based on its outcome and not on the process by which the decision was reached. In other words, the quality of a decision is only determined once the outcome is known. Outcome bias occurs when a decision is based on the outcome of previous events without regard for how those events developed.

Hindsight Bias

hindsight-bias
Hindsight bias is the tendency for people to perceive past events as more predictable than they actually were. The result of a presidential election, for example, seems more obvious when the winner is announced. The same can also be said for the avid sports fan who predicted the correct outcome of a match regardless of whether their team won or lost. Hindsight bias, therefore, is the tendency for an individual to convince themselves that they accurately predicted an event before it happened.
