The leading hypothesis is that the hippocampus plays out the stored information to memory networks throughout the brain. During this reorganization and consolidation of memories, he said, the brain creates a more useful representation of information than what was stored during the actual experiences. With the disappearance of Australopithecus one million years ago, homo erectus was the sole surviving representative of hominid evolution. The men, women, and children of this particular species were the first true humans, and with much bigger brains and control of fire began to spread out across the planet in the greatest expansion of a single biotype in the history of life on earth. Standing alone, Centuries 5,4,3 is fully Darwinian and non-anthropic.
All major continents hold humans.
All humans are gatherers and hunters, harvesting the local flora and fauna. In the southern Levant, in the Indus valley, in the coastal regions of the northern Andes, humans who used fire to move about in Centuries 3 now use farming to stay put and expand at Centuries 2 . The engines of history are started. Things are counted. Walls are built.
