Extinction

There are about 4,300 mammalian species on the planet today. There are more than 200,000 mammalian species that came before us and are now extinct. There are 200 species or primates on the earth today. There were 6,500 primate species in the past that are now gone, extinct.

The is only one homo species around today. Homo sapiens - Humans. There have been at least 20 homos. I am told.

Most of the large mammals of today will be gone, extinct, in the near future. Elephants and rhinos will not be around long. Or bears. Or tigers or lions. There simply is not enough room for them. And humans do not have the capacity for the changes that would be necessary for them to survive.

Most species last around 1,000,000 years before they go extinct or evolve into a new species. Canines have beat that by a broad margin. Homo sapiens just got started. Or did you? Many dogs are nervous about that question.
