Approximately 8,000,000 BC: The primate ancestors of 20th century human beings are diverging genetically from gorillas now

20th century gorilla and human DNA will be 97.9% identical.

Just how intelligent and socially complex are apes anyway? Well, for one thing they (as well as certain other animals) appear to have developed some limited forms of medical practices to cope with digestive problems and various parasite infestations. Some primates (monkeys) have even gone so far as to practice birth control and biologically engineering the sex of their progeny.

Various animals from cats and dogs to bears and apes appear to self-medicate themselves when necessary with the eating of certain plants. Certain monkeys appear to increase or decrease the chances of pregnancy in the same way-- as well as also sometimes select the sex of their offspring. Usually the purposeful engineering of fertility and sex of progeny appear to be based on the social environment of the group, among other things (the current difficulties of survival may also play a role).

One aspect of such findings which make them all the more puzzling is that many of the medicinal plants the animals use appear to taste bad to them.

At least two gorillas will be considered by some to have learned human language by early 2000 AD. They will communicate via sign language.

In the far off 20th century gorilla lifespans will be known to extend into the fifties, except where heart disease or other afflictions have cut it short.

Gorilla family units usually consist of one dominant male and several female mates.

This may be where the ancestors of 20th century Bonobo chimpanzees and humans are parting ways too, genetically speaking.
