Question

Quizplus · Accepted Answer

The presence of certain genes responsible for initiating eye development in both humans and fruit flies suggest a genetic toolkit for development that is common to both species. This commonality is likely the result of shared ancestry and evolutionary history. The other options (complete genome, use of ATP in energy-transfer reactions, homunculi, duration of pregnancy) do not directly relate to the evidence of shared genes for eye development.
