Types of Selection

Types of Selection

Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...

Competition

Competition

When organisms require the same limited resources within an environment, they may have to compete for them. Competition is a net-negative interaction. Even if two competing individuals or populations do not interact directly, the overall fitness of both competitors is lowered as a result of not having full access to the limited resource.

Microbial Interactions: Competition

Microbial Interactions: Competition

Microbial competition is an ecological interaction in which microorganisms vie for limited resources within shared environments. These resources may include nutrients, space, or light, depending on the system. The intensity and outcome of competition are influenced by the environmental context, such as nutrient availability, spatial constraints, and the diversity of microbial species present. These competitive interactions significantly influence the structure, function, and resilience of...

Inclusive Fitness

Inclusive Fitness

Most altruistic behavior—in which one animal helps another at a cost to themselves—occurs between relatives. Scientists think these altruistic behaviors evolved because they increase the inclusive fitness of the animal providing help.

Frequency-dependent Selection

Frequency-dependent Selection

When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

Summary

This summary is machine-generated.

Individuals help or harm others based on their genetic relatedness to their community and the recipient. Lower relatedness to the community promotes helpfulness, influencing social behavior and community dynamics.

Area of Science:

Evolutionary Biology
Behavioral Ecology
Population Genetics

Background:

Kin selection theory predicts helping behavior among relatives.
Competition for resources may drive harmful behavior towards neighbors.
Understanding the evolution of social behavior requires analyzing costs and benefits of helping/harming.

Purpose of the Study:

To derive conditions favoring helping or harming behavior in social interactions.
To investigate the role of relatedness to the community and recipient in shaping social actions.
To explore how differing relatedness affects the evolution of altruism and spite.

Main Methods:

Mathematical modeling of social interactions between two individuals.
Derivation of selection conditions for helping and harming behaviors.
Analysis of relatedness coefficients within a community structure.

Main Results:

Selection favors helping when an individual is less related to the community.
Increased joint relatedness to the community reduces helpfulness between individuals.
The less related an individual is to the community, the more helpful it tends to be.

Conclusions:

An individual's relatedness to its community is a key factor in determining helping or harming behavior.
Social interactions are influenced by the interplay between relatedness to the recipient and the broader community.
The structure of social interactions (assortative vs. random) and opportunity distribution modulate these selective effects.
