To calculate rates of mutation in the zinc fingery gene Dorit and his team compared DNA sequences. Realizing more research needs to be completed in order to link certain species, it is feasible that the close similitude between gorilla DNA and human DNA is a cause for their close characteristic social behaviors. Primates are our closest relative in the primate family. For example they have functional hands, functional thumbs, an intelligence level, and they have the ability to learn, not only through imitation but through trial and error. Primates are the most well developed mammals.
Primates can stand up for long periods of time.
In an article written by Byrne, he shows how mountain gorillas have learned complex techniques. He states how gorilla's stomachs are similar to humans in that they are not capable of neutralizing poisons from plants. After many observations he and his wife figured out that the gorillas had a special technique in order to fill their stomachs. The most dominate sources of food in the meadows are nettles and wild celery. The gorillas have devised a technique to tear away the hard spines without causing pain and being able to eat the sweet fruit inside.
