Consider natural selection and biocultural evolution. Why do you think anatomically modern humans were more reproductively successful than other contemporary hominins? Or were they? 2 - Why do you think such a small portion of Neandertal or Denisovan DNA exists in the gene pool of modern humans? Why not more? 3 - How might have anatomically modern humans avoided waiting tens of thousands of years for advantageous mutations to pop up that would allow them to adapt to all of these new environments they encountered as they dispersed across the Old World? What might have been a faster way for them to adapt to these environments that the groups who were already in the region had already adapted to? 4 - How does admixture between different regionally adapted populations increase a species chances of survival?

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:
