Which of these conditions should completely prevent
the occurrence of natural selection in a
population over time?
a. All variation between individuals is due only to environmental
factors.
b. The environment is changing at a relatively slow rate.
c. The population size is large.
d. The population lives in a habitat where there are no competing
species present.
Homework Answers
Option A is correct If the variation in a population is only due to environmental factors.
so whenever there is a change in environmental factors those species which easily adapt or make the variation in individuals according to the environment have a better chance of survival and do not get extinct by natural selection.
Hence this prevents the occurrence of natural selection in a population over time.
