Question: If humans evolved from monkeys, then why are there still monkeys? Humans did not evolve FROM monkeys. We evolved from a Common Ancestor. In the beginnging: This is a single cell. At some point, the cell copied itself to form two cells. However, the second cell (grey) came out different in some way. It had a mutation. The mutation allowed the second cell to eat pink food, something the original cell could not do. The white cell, however, can still only eat yellow food. When the yellow food one day begins to disappear from the environment, suddenly this mutation is critical to the survival of the grey cell survival. This is what we call Adaptation. Time This adaptation continued to happen with all life as it spread into new environments. Over thousands of generations and millions of years, these adaptations accummulate until life looks very different from when it started, with only the most well adapted species surviving. This process is known as: Natural Selection A similar process happened with man. The traditional image that represents the evolution of man is this: A fM However, this process is more accurately conveyed through a different, slightly more complex image: Approximate DNA similarity to humans: 75 - 80 % H 80 - 85 % Я 85- 90 % 90 - 95 % ■ 95 - 100 % M-H'Ullll.lf Unfortunately, these guys just didn't make it to the present day. So while we have a common ancestor with monkeys, we didn't evolve from them directly, if anything we evolved with them. Thank you for reading. Please Note: While this image attempts to accurately portray the process of evolution, it is still a grossly over-simplified version of a very complex process.
