\. Read some papers (find them using any of several literature-search engines that your instructor can suggest) that make different estimates of the timing of either the origin of bilaterian animal phyla or the orders of mammals. How different are the estimates based on molecular clock evidence versus paleontological evidence? What might account for these differences, and how might they be resolved?

Human Evolution

Human evolution is the process of evolution of humans from early man to anatomically modern humans. The process of evolution in humans leads to the gradual development of traits like bipedalism. Humans are the highly social animals that make them the most advanced animal on Earth.  Human evolution is an outcome of interaction among the following processes:
