Question

The discovery of DNA and genes proved that:

A) bats and butterflies have a very close common ancestor
B) mutations create variations and come from genes
C) Darwin was wrong
D) natural selection is a random process that makes organisms better adapted to their environment

Answer 1

B

The discovery of DNA and genes would imply that traits come from genes, which are found in DNA. Mutations create variations, which prove Darwin's theory to be correct; if natural selection was a random process that made organisms better suited to their environment, then there would not be genetic variability in any organisms.
