Which evolutionary mechanisms could affect allele frequencies in a population being maintained in captivity?
Genetic drift, selection pressures imposed by captivity conditions, inbreeding, and genetic bottlenecks due to small population sizes are some evolutionary mechanisms that can affect allele frequencies in a population being maintained in captivity. These factors can lead to changes in the genetic diversity of the population over time.
Is necessary for natural selection to act on a population of organisms?
Yes, natural selection is essential for driving evolutionary change within a population of organisms. It acts on heritable traits that affect an organism's survival and reproduction, favoring those individuals with advantageous traits. Over time, this can lead to adaptations and the evolution of new species. Without natural selection, populations may not adapt to changing environments, which can lead to decreased survival rates.
Why is natural selection in offspring?
Natural selection acts on offspring because they inherit genetic variations from their parents that may affect their survival and reproduction. Those offspring with advantageous traits are more likely to survive, reproduce, and pass those traits on to future generations. Over time, this process leads to the adaptation of populations to their environments. Therefore, natural selection drives evolutionary change by favoring traits that enhance fitness in a given context.
Why does natural selection not directly affect genes?
Natural selection acts on the way organisms interact with one another and with their environment. The genes of organisms are not usually themselves involved in this interaction: they direct it through intermediaries such as proteins. So natural selection must work through these intermediaries to affect genes.
What happens to unnecessary traits during the process of natural selection?
How does natural selection affect undesirable traits?
How does Evolutionary Trends affect Irreversibility?
Air-breathing animals do not return to breathing water.
How does selection affect natural selection?
Organisms are affected by Natural Selection because Inherited characteristics affected the likelihood of an organism's survival and reproduction.
Which does natural Which does natural selection affect?
natural selection is basiclly only the strong survive which means it effects the weak by killing them but bernifits the strong
How does natural selection affect survival?
Natural selection is the process which determines the shark's evolution. It is humankind that is threatening the sharks' survival.
Which does natural selection affect populations or individuals?
Populations evolve, but individuals are selected. Natural selection affects individual organisms.

What is a requirement for evolutionary changes to occur through natural selection?
A requirement for evolutionary changes to occur through natural selection is the presence of genetic variation within a population. This variation can lead to differences in traits that affect an organism's ability to survive and reproduce. Over time, individuals with advantageous traits are more likely to pass on their genes, causing those traits to become more common in the population.
Why is natural selection in offspring?
Natural selection acts on offspring because they inherit genetic variations from their parents that may affect their survival and reproduction. Those offspring with advantageous traits are more likely to survive, reproduce, and pass those traits on to future generations. Over time, this process leads to the adaptation of populations to their environments. Therefore, natural selection drives evolutionary change by favoring traits that enhance fitness in a given context.
What other theories are there except for natural selection?
Evolution by natural selection is currently the only viable theory explaining the diversity of life. However, the mechanism of natural selection is not the only mechanism to affect evolution. There are phenomena such as genetic drift, biased gene conversion, intragenomic conflict, and so on, that aren't exactly the same as natural selection (although they are all intertwined and all affect one another), but do affect the direction of evolution.
How does nonrandom mating affect evolution?
Non-random mating is otherwise known as sexual selection. Some see this as distinct from natural selection, but I think that sexual selection is merely a form of, or perhaps more a complication of natural selection. Selection, natural or sexual, is the effect that "guides" evolution, that allows evolution to produce populations suited to their environment.
When a population is split into smaller groups. why do these groups develop different traits?
Evolutionary mechanism work on the two subgroups independentlyWhen a group is split forces like natural selection and genetic drift affect the genes of the two subgroups differently. Mutations that arise in one group are not passed to the other group through reproduction.
