There's the upper arm..” My textbook would show the forelimb, a hand and it would show a bat swing and a whale's flipper and say because they have similar structure, you have similar bone pattern, that they must share a common ancestor. “And then the five very long fingers just like yours” Homology was something that biologists discovered long before Darwin. Aristotle knew about homology. The real question about homology is how do we explain it. There are plenty of examples of homological structures in biology, which are obviously not based on common…
