Lynch's research on nest-building in mice suggests that natural selection could have an influence on that behavior. This is based on evidence that
A) mice build larger nests in the South than in the North.
B) mice from lines that built larger nests raised more pups at 4°C than did mice from lines that built smaller nests.
C) mice from lines that built smaller nests raised more pups at 4°C than did mice from lines that built larger nests.
D) pup survival in both lines was reduced overall at colder temperatures.

Question

Quizplus · Accepted Answer

Lynch's research indicates that mice from lines that built larger nests were more successful in raising pups at colder temperatures (4°C) than those from lines that built smaller nests. This suggests that the behavior of building larger nests could be favored by natural selection in colder environments, as it directly contributes to higher offspring survival rates.
