True or false: Theoretically, it is possible (but very difficult) for a population to not evolve for a while.
Debora [2.8K]

It is true that it is possible for a population to not evolve for a while.

There is something called the Hardy-Weinberg theorem, which characterizes the distributions of genotype frequencies in populations that are not evolving.

There are 5 Hardy-Weinberg assumptions:

  • no mutation
  • random mating
  • no gene flow
  • infinite population size
  • and no selection (natural nor forced).

You can see that some of these are kinda extreme and really hard to get, but with approximations, we can work.

For example, instead of an "infinite population size" we have enough with a really large population, such that genetic drift is negligible.

Concluding, yes, it is possible (but really difficult) for a population to not evolve for a while (at least, in nature), as long as the 5 assumptions above are met.

b. behavioral isolation

Explanation:

It is a type of reproductive barrier that can lead to speciation. Behavioral behavior, such as mating rituals as in when two populations of the same species show some difference in behavior, typically in mating rituals

and signals.
