Question

1. one of lamarcks mistakes was believing: a) traits were inherited through genes b) genes changed by activities in life c) fossils showed evidence of evolution d) populations varied

Explanation:

Lamarck proposed the inheritance of acquired characteristics, believing that organisms could change their genes through activities in life and pass these changes to offspring. This is incorrect as we now know that genetic changes occur through mutations and are not directly due to life - activities. Traits are inherited through genes (a correct modern - day concept), fossils are evidence of evolution, and population variation is a key aspect of evolution, but these are not Lamarck's mistakes.

Answer:

B. Genes changed by activities in life
