Answer:
explanation below
Explanation:
When scientists look at the early development of different organisms, they do so by studying the embryonic state of their development. If has been observed that most embryos look alike in their early stages of development, mostly when they are of similar species.
So the closer the similarity in their embryos, the closer the genetic relationships between the organisms and the organisms will continue to look similar for a very long period of time since they share common ancestor.
When we look at the embryos of a human being and that of a chimpanzee, they look similar while they look so differently at their adult stages.
