Chapter 10 - The Sexual Evolution

In Chapter 10, The Sexual Evolution, many interesting ideas are discussed. The relationship between neanderthals and us compared to chimpanzees and pygmy chimpanzees is a very unique way of thought. We do have many DNA similarity but the differences should make the comparison almost impossible. Neanderthals seem no more related to us than the chimpanzees are related to us. After reading this article, I am wondering who and when someone is going to compare humans to birds since we both start off as an egg at some point of our lives. This may seem like a far stretch but so is trying to compare the sex live of an extinct species to an existing species when there are no written evince to even look at to start the beliefs. As stated, the author doesn't even know how many children each women from the neanderthals gave birth. The explanation of them not having sex could be just as easily explain as a longer gestation period for neanderthal babies or more miscarriages do to the harder life they lived. I feel that a judgement of why need to come before the comparison of species.
