His book sold like hockin icks and created a stir among people. There is a big commotion in scientific and academic conferences. The origin of species is a false theory. IT doesn't believe in god. Humans ancestors . are monkey . far from IT, but people gradually began to recognize Darwin's argument based on a lot of data and well grounded information.

I'm a human. These are my parents. They are clearly humans to my grandfather, human man, my great grandfather and great, great grandfather, humans, without a doubt. But my grandfather, one hundred and eighty five million generations removed, not a human. He was a fish. So imagine you could take a picture of every ancestor down the line and put him in a big stack. every father's fathers, father's fathers, fathers, father's fathers, fathers, fathers, father's fathers, father's father. And well, that will be a very big stack with me at the top and my fishy four father all the way down at the bottom. Maybe we should lay the stack down its side. That would be a little safer.
