Question 11 • CA-Integrated Science 8 B

Which idea is most directly related to Lamarck’s beliefs about evolution?

Answer

A

A frog’s legs grow during its lifetime to help it jump farther, and it passes on the longer legs to its offspring.

B

Humans and primates are classified in the same genus because they have similar traits.

C

If a population is left to reproduce without limiting factors, it will outgrow its food supply.

D

In one area, brown moths are better adapted to the environment than white moths, so they survive and reproduce.

Explanation

Lamarck proposed that organisms acquire traits during their lifetimes through use or need, and then pass those acquired traits to their offspring. Choice A describes a frog developing longer legs during its life and inheriting that change to its young. Choice D instead describes natural selection, which is associated with Darwin’s theory.
