Why do we need to group animals?



  1. 0 Votes

    Scientists group animals not only to have some organization but also to keep track of animals that are closely related to eachother.  Since Darwin, scientists have been classifying animals in sort of a family tree to track changes and adaptations that have occurred between animals, telling us a little more about them.  Over 3 billion years of evolution has led to millions of animal species, and grouping is the only way to really keep tabs on them.
