Imagine walking through a tropical rainforest. You notice that there are different types of trees, birds, insects, and other organisms. A few weeks later you are taking a walk through the desert and notice that the trees, birds, insects, and other organisms are different than those you saw in the rainforest. Which of the following statements best explains the differences between each of these ecological systems? Organisms in each ecological system are there by chance and their presence in different ecological systems does not have a biological explanation. Organisms in each ecological system have short dispersal distances and are confined to populations in the area where they mate. Organisms in each ecological system have not had enough time to evolve the adaptations for the other ecosystem; with enough time they will evolve into the other ecological system. Organisms in each ecological system have not had enough time to evolve the adaptations for the other ecosystem; but exhibit common ancestry Organisms in each ecological system have evolved in that system and have adaptations suited for that environment.

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:
