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.

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...

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.Positive Frequency-Dependent SelectionIn positive...

Natural Selection and Mating Preferences

Natural Selection and Mating Preferences

The principle of natural selection posits that organisms better adapted to their environment are more likely to survive and reproduce. This principle is closely intertwined with mating preferences, a key aspect of sexual selection, which evolutionary psychologists believe is driven by instincts to propagate one's genes. Such instincts significantly influence mating behaviors and preferences between genders.
Females, due to their biological roles in conception, pregnancy, and nursing, inherently...

Limits to Natural Selection

Limits to Natural Selection

Organisms that are well-adapted to their environment are more likely to survive and reproduce. However, natural selection does not lead to perfectly adapted organisms. Several factors constrain natural selection.For one, natural selection can only act upon existing genetic variation. Hypothetically, redtusks may enhance elephant survival by deterring ivory-seeking poachers. However, if there are no gene variants—or alleles—for redtusks, natural selection cannot increase the prevalence of...

Genetics of Speciation

Genetics of Speciation

Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.The genetics of speciation involves the different traits or isolating mechanisms preventing gene exchange, leading to reproductive isolation. Reproductive isolation can be due to reproductive barriers that have effects either before or after the formation of a zygote. Pre-zygotic mechanisms prevent fertilization from occurring, and post-zygotic mechanisms...

Area of Science:

Evolutionary biology
Social evolution
Behavioral ecology

Background:

The direct-fitness approach offers an alternative to inclusive-fitness models for studying social traits.
Existing direct-fitness models have not yet been extended to analyze dynamic traits, which vary over time.

Purpose of the Study:

To extend the direct-fitness approach to analyze the evolution of dynamic social traits.
To model dynamic resource-allocation behavior that influences the fitness of relatives.

Main Methods:

Applied the direct-fitness approach to a dynamic resource-allocation behavior.
Utilized standard social-evolutionary model components: reproductive value, fitness changes, and relatedness measures.
Validated analytical results using a genetic algorithm.

Main Results:

Successfully implemented a modified direct-fitness model for dynamic traits.
Demonstrated the model's application with a previously studied example.
Showcased how the direct-fitness perspective aids in validating analytical findings.

Conclusions:

The direct-fitness approach can be effectively extended to study the evolution of dynamic social traits.
This extended approach provides a valuable tool for analyzing complex behavioral evolution.
The direct-fitness perspective enhances the validation of theoretical models in social evolution.
