PREMISE: The cause of the EXPLOSION OF HOMINID SPECIES IN THE FACE OF THE DECLINE OF APES, due to deteriorating climates 6 million years ago, WAS A MAJOR EVOLUTIONARY INNOVATION.
It would logically follow that:
1. The single most important characteristic that identifies an ape as a hominid – BIPEDALISM – would be central to the function of this innovation.
2. This innovation enabled early hominids to “INDOLENTLY THRIVE” – they grew huge teeth and grazed on low quality foods for 3½ million years in a large variety of African environments and underwent remarkable speciation (a new species of hominid is found practically every year.)
3. This same innovation was instrumental in propelling the Genus Homo, starting 2½ million years ago, far beyond all other life in the ability to MAKE TOOLS and GROW HUGE BRAINS.
4. This same innovation formed the foundation for the unique human attributes of SYMBOLIC LANGUAGE and SELF AWARENESS.
Apes, Ants, and Ancestors is about this miraculous evolutionary innovation and all of its implications.
