The debate of human evolution being fact or fiction has been around for hundreds of years. Evidence of human ancestry has been found in many parts of the world and these fossils found have been proven to be human. The parts of the world include Eurasia and Africa. Although fossils are found in Eurasia, the human ancestor the Hominoidea has been traced back to the Miocene epochs, which were 23 to 5 million years ago. The Hominoidea is a super-family, which contains many species that are existent today including: gibbons, orangutans, gorillas, chimpanzee, and humans. Throughout history humans have migrated and evolved, as evolution occurred humans became more technologically advanced, while the other species in Hominoidea remained the same. …show more content…
It closely resembles an enigmatic lineage of human the Denisovans, which until this piece of DNA was found were in Siberia eighty thousand years ago. The anatomical and genetic divergence appalled scientists, thus altering human evolution in the last few hundred thousand years. Morally, human evolution has become even more of a mystery in one portion, while another is well defined. An allusion at new complexity came from a femur in a cave called Sima de los Huesos. The DNA from the femur once again was Denisovans, thus corroborating they weren’t just in Siberia. Since the seventies scientist have brought back several fossils from Spain. Dr. Arsuaga alone has found twenty-eight complete skeletons of humans over three decades. DNA from Spain explained that the humans in the cave were neither Neanderthal or Denisovan, but a hybrid of the two. Beth Shapiro an expert in ancient DNA believes the humans from Sima de los Huesos could be yet another branch of humans. Humans have been interbreeding with the other species too, proven in a discovery that Neanderthal and human interbreed approximately fifty thousand years ago (Zimmer, 2013). There are four initial stages of human evolution that don’t include pre-human primates which are: Australopithecus, three million years ago; Homo habilis, two million years ago; Homo erectus, one million years ago; and Homo sapiens, two hundred thousand years ago to present-day. Human derivation and evolution transpired in the tropical
