With the10 comparisons between chimps and humans. These are the ten comparisons number of species, DNA, brain size, sociability, language and facial expressions, diet, sex, walking upright, eye and the tools used. Humans and both chimpanzee species evolved from a common ancestor, possibly sahelanthropus tchadensis, between five and seven million years ago. Only fossils of this ancestor remain. Chimpanzees and Humans share 99% the same DNA. With the genetic comparison is simple due to the nature of gene repeats and mutations, but a better estimate is somewhere from 95% to 85%. But most DNA is used to basic cellular functions for all living things share. Like, for example, we have about half the same DNA as a banana, and but yet people do not use this to be similar. The human brains …show more content…
This number of 1% was based on the sheer similar genes. The 6% was from a new method that takes gene duplication and protein function into account. The research also shows some of the traits have a neurobiological basis, and that those features vary according to the sex of the individual chimpanzee.
The researchers analyzed complete questionnaires for 174 chimpanzees housed at the Yerkes National Primate Center at Emory University. They ran extensive individual analyzed to find out which traits tend to go together, and which combine to make more basic, fundamental "meta-traits."( www.science20.com)
The analysis showed that the most fundamental personality trait for chimpanzees is dominance that is, whether an animal is a dominant and under a controlled with Alpha or a more playful and sociable Beta.
But those two big categories can be broken down statistically into smaller personality traits in ways that echo the personality structures researchers have repeatedly found in child and adult human
