A population of mice lives along a river. Some mice cross the river to establish a new population. Eventually, due to genetic changes, these two groups of mice can no longer interbreed. This is an example of
A)speciation.
B)genetic drift.
C)artificial selection.
D)creationism.

Question

Quizplus · Accepted Answer

The scenario described is a classic example of speciation, where a single population separates into two distinct populations that evolve separately over time until they can no longer interbreed. This is a natural process that occurs due to genetic changes in the populations. Genetic drift is a random process that can lead to changes in the gene pool of a population, but it may not necessarily lead to speciation. Artificial selection is a process where humans select certain traits in a population to breed and does not involve natural genetic changes. Creationism is a religious belief and not a scientific explanation for the origin of species.
