The_Origins_Of_Humans.

The Origins Of Humans. The Origins of Humans. The question of where humans originated has been a pressing question for a very long time. There are many explanations, mythical, scientific and religious, but nobody can know exactly where we came from for a few reasons. One is that our fossil record is sparse, and modern-day technology cannot compensate for this. Another is that there are ethical concerns, such as what humans would do with this knowledge and whether we are trying to ‘play God’. Still, this question will not go away and this essay will attempt to cover some aspects of a powerful study. The event that ultimately initiated human evolution was the fragmentation of the rainforest in East Africa, around 10 million years ago. This occurred when the Arabian Plate and the African Plate began to move apart, resulting in a fissure just below the Red Sea, called Great Rift Valley. Land to the east of Rift Valley was in rain shadow, so food became sparser. Early apes had adapted to the rainforest, however, and did not have an efficient way of travelling long distances to get food because they hadn’t needed this skill in the rainforest.
