Approximately 60% of human genes are also found in fruit flies. about 97.5% of human genes are also found in mice. what does this evidence suggesta.  mice have had more mutations and recombinations during their evolution than fruit flies. b.  humans and mice share a more recent common ancestor than do humans and fruit flies. c.  fruit flies have had more mutations and recombinations during their evolution than mice. d.  mice and fruit flies share a more recent common ancestor with each other than with humans

B

Factoid:

Hats why we test products and experiment on mice and rats.

B. Humans and mice share a more recent common ancestor than do humans and fruit flies.

Explanation:

The species closer to each other in terms of evolution share more number of genes with each other than the distantly related species. Since human and mice share 97.5% genes with each other, these two species might have diverged from each other more recently than human and flies. Lesser gene homology between human and flies represents their distant evolutionary relationship.

your answer is "the 1950's"
