Based on their anatomical and behavioral differences, biologists previously placed humans and chimpanzees in different families, but now DNA sequence data suggest that they are closely related and should be placed in the same family. What are some advantages of using DNA sequences to decide how to classify organisms? What might be some disadvantages?
What is the significance of taxonomic process in animals?
A 2015 article in Nature has summarized the early history of jawed vertebrates using highlights from recent discoveries and how they have changed our understanding of vertebrate evolution.
