WHAT ABOUT US?
What is Darwin's theory of Evolution?
The theory of Darwin suggested that all living creatures are related to one another. The fishes, the birds, the mammals, the plants, and so on all have a common ancestor. There might just have been modifications and mutations that came along the long process of evolution.--KimberlyR 16 mars 2012 à 15:43 (CET)
Where were the first Humans found?
Darwin supposed that the early humans first lived in Africa, then migrated out of Afica and then into Asia about 2 million years ago. And then eventually reached Europe.--KimberlyR 16 mars 2012 à 15:43 (CET)
What are the human's ancestors?
Darwin thought that homosapians came from Africa because our closest relatives, gorillas and chimpanzees are found there.--KimberlyR 16 mars 2012 à 16:21 (CET) But the author is sceptic about it, because there are no concrete evidences, no fossils to prove that.--KimberlyR 16 mars 2012 à 16:21 (CET)
Darwin affirmed that humans had evolved from apes. He said that the mutation of the apelike species, which included the higher mental faculties of humans could be explain by the natural selection...
Our common ancestor
Who discovered the first fossil ancestors?
In 1871, the physician Eugene Dubois had discoverd in Java a human fossil. The skull was more robust than humans and the size of the brain was smaller. This fossil was too humanlike to be the missing link between us and apes. But distressed by the opposition between religion and science, Dubois decided to buried the fossil of Homo erectusin his house and he hid it for three decades.
In 1924, Dart a professor of anatomy at the University of Witwatersrand, but also an amateur of anthropology had discovered one of the greatest fossil. While he was at a wedding, a postman brought him two boxes containing bones fragment. When he oppened the boxes, he discovered a replica of a brain three time larger than a baboon's brain and bigger than a brain of an adult chimpanzee. The size of this replica of the brain was not big enough to be a primitive man, but it was much bigger than ape's brain. Dart is the one who discovered the first Australopithecus africanus.
