Evoblog 5 Weblab Explore Evo

In this interactive weblab I explored the lines of evidence that scientists use to reconstruct the evolutionary histories of organisms. I worked with whales who are mammals like horses and humans, but they live in the ocean. In this lab I has to go through DNA, anatomy and fossil evidence to track down the history of the whale. I learned that whales evolve from a group of artiodactyls or even-toed land mammals since the anatomy evidence show that whales are closely related to animals that had rear legs and concluded that they lived on land. The DNA evidence also show that they are also closely related and the fossil evidence concluded that whales carried artiodactyl-style ankle bones.. From this lab I learned that in order to find lines of evolution scientists must be observant to specific details that are on fossils and must compare bones of the likely ancestors well enough to track down the right ancestor. Scientists must go through a lot evidence in order to find the ancestor of any animal since a mistake could lead to wrong assumptions on the evolution of all animals.
