Question

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

A frog’s legs grow during life to help it jump farther, and it passes on the longer legs to its offspring.
Humans and primates are classified in the same genus because they have similar traits.
If a population is left to reproduce without limiting factors, it will outgrow its food supply.
In one area, brown moths are better adapted to the environment than white moths, so they survive and reproduce.

Answer 1

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

Step-by-step explanation:

Lamarck believed that accumulation of small changes through successive generations promote the developement of new organs or characters which are transmitted to the offspring in the next generation (such as elongation of frog's leg). This is called inherirance of acquired characters.
