There were two groups: the Kiffian, who were powerful hunters and fishermen, and the Tenerian, who were smaller pastoralists (herders) and fishermen.
Individuals at the Kiffian sites averaged over 6 feet tall, with some reaching 6' 8". They were powerfully muscled, and found with the remains of elephants, giraffes, pythons, giant perch and other large game.
Not that you have to be Conan the Barbarian to kill an elephant. Forest pygmies traditionally hunt elephants, and there's a picutre in Nutrition and Physical Degeneration to prove it. They use stealth, agility and an intimate knowledge of their prey to make up for their small size and primitive weapons.
Both the Kiffians and the Tenerians had excellent dental development and health. Take a look at some of the pictures. Those are the teeth of a wild Homo sapiens. Straight, free of decay and with plenty of room for the wisdom teeth. They must have had good dentists.
Both cultures also showed a high level of intelligence and empathy. They were found with decorated pottery shards and their bodies were arranged in imaginative and empathetic ways. A man was buried sitting on a tortoise shell. A mother was buried with her two children. Here's the picture. I can't say it better than the LA Times:
Among the Tenerian graves was a heart-rending burial tableaux [SIC!!]: A young woman was lying on her side. Pollen under her body suggested that she was placed on a bed of flowers. Lying on their sides facing her were two young children, their fingers interlocked with hers, leaving a tangle of bones.Haha, I couldn't let the spelling error slide, it should be 'tableau'. Hey, I'm half French, give me a break. ADS LINK 200 X 90
