Answers
Answer:one of them ls the genetic structures of these species like the drosophilia and other organisms these insects can genetically change their eye colour
-the fossil record where fossils were formed by settling on lakes and oceans .
-circumstantial evidencedone by studying the distribution of modern animals and their structure

Answer:
Analysis of the organ structure in fossils allows us to make estimates of how far evolutionary relationships go. For example, presence of feather in some fossils dinosaurs indicate the birds are closely related to reptiles.
