As most of us learned in our biology classes in high school, we were told that the human species evolved from apes (chimpanzees). The "Theory of Evolution by Natural Selection", was first published in 1859 by Charles Darwin, a British Naturalist, Geologist, and Biologist. He claimed that we evolved over the millions of years from apes into humans. The question which comes up when discussing Darwin's theory is - if we did evolve from apes, how come we still have apes?
Today, we have similar questions that seem to be taking hold in certain parts in communities around the world, that males can become females, and females can become males. The logic of both theories can logically be challenged, but if you challenge those theories you will be called a "science denier" or worse.
