These days in the earth, some creatures are living. But that creatures are us, humans. Human is smartest animal until now. But  you know what?

     Back in the days there were no humans. Some peoples are saying that monkey evoluted to a human. I agree in this theory. Back in the days monkeys were eating just raw meat so their jaw were really big because raw meats were uncomfortable to chew.

     As time goes by, they were use to use a fire. So they grilled the meats so meats were soft to chew so these days our jaw are small. If you look at te monkey's jaw compare to our jaw you coud see the differences.

     If living things or some creatures are using something new,then it will going to develop. Like a good example of monkey, they were  using something really useful so it developed and maybe became to humans.
