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.Intraspecific competition, which occurs between individuals of the same species, serves as a natural mechanism for regulating population size. Too much...

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.

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...

Hybrid Zones

Hybrid Zones

Hybrid zones are narrow regions where two closely related species interact, mate, and produce hybrids. Relative to either parent species, hybrids may possess distinct phenotypic or genetic differences that impact their survival and reproductive success. The genetic variances introduced by hybridization influence species diversity and speciation processes within the hybrid zone.Gene flow and natural selection are evolutionary mechanisms that shape the outcome of a hybrid zone. Gene flow...

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...

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...

Prenatal effects link parent-offspring conflict and coadaptation. When offspring control provisioning, parents benefit from prenatal effects. When parents control provisioning, offspring benefit, highlighting conflict

Area of Science:

Evolutionary biology
Behavioral ecology
Quantitative genetics

Background:

Family life evolution studied separately by behavioral ecologists (parent-offspring conflict) and quantitative geneticists (parental supply and offspring demand coadaptation).
Existing research lacks a unified framework connecting these two approaches.

Purpose of the Study:

To demonstrate how prenatal effects on offspring begging behavior can bridge the gap between behavioral ecology and quantitative genetics in studying family life evolution.
To investigate the role of parent-offspring conflict in driving the coadaptation of parental and offspring traits.

Main Methods:

Theoretical analyses of evolutionary models.
Experimental investigations into offspring begging behavior and its prenatal influences.

Main Results:

When offspring control provisioning, prenatal effects primarily benefit parents, driving coadaptation through selection on parents.
When parents control provisioning, prenatal effects primarily benefit offspring, driving coadaptation through selection on offspring.

Conclusions:

Prenatal effects are a key mechanism linking parent-offspring conflict and coadaptation.
Parent-offspring conflict is a significant selective force shaping the coevolution of parental and offspring traits.
