A spider is found high on several mountain tops.  The spider species is not capable of living in warmer temperatures and is only found in small populations at the tops of the mountains.  The spiders on each mountaintop have a different color (e.g. red on one mountain, yellow on another mountain) even though the habitat is the same on all the mountaintops.  What evolutionary force is likely causing the variation in spider color between mountain ranges?

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:
