A population of 600 scorpions was split into four populations when irrigation canals were built through their habitat. The four new populations were called the Northern, Southern, Eastern, and Western populations. Each new population consisted of about 150 individuals. The four populations continued to evolve, and no migration occurred among populations. One hundred generations later, each population still has about 150 individuals, and a biologist investigates them.

Consider what a biologist expect to see in the four populations after 100 generations if the environment did not change for any of the populations. Would the biologist agree or disagree with the following statements?

Given the information at the top of the page, would the biologist agree or disagree with the following statement?

In the smaller populations of 150 individuals, the processes leading to genetic drift could have a stronger influence on a gene than natural selection.

Differences among the four populations probably occurred when populations adapted to specific environments because most evolution results in adaptation.

Beneficial mutations would be more likely to occur in populations that had a greater need to adapt to their location.

Chance survival of some individuals occurred in some generations, but not every generation.

Each population would probably have fewer alleles-that is, versions of genes-than it would have had 100 generations ago.
