All people todayare classified asHomo sapiens. Our speciesof humansfirst began toevolve nearly200,000 years agoin association with technologies not unlike those of the early Neandertals. It is now clear thatearlyHomo sapiens, ormodern humans,did not come after the Neandertals but were their contemporaries. However, it is likely that both modern humans and Neandertals descended fromHomo heidelbergensis.
Compared to the Neandertals and other late archaichumans, modern humans generally have more delicate skeletons. Their skulls are more rounded and their brow ridgesgenerallyprotrudemuchless. They rarely have the occipital buns found on the back of Neandertal skulls. They also have relatively high foreheads, smaller faces,and pointed chins.
The first fossils of earlymodern humansto be identified were found in 1868at the 27,000-23,000year oldCro-Magnonrock shelter site near the village of Les Eyziesin southwestern France. They were subsequently named theCro-Magnonpeople. Theywere very similar in appearance to modern Europeans. Males were 5 feet 4 inches to 6 feet tall(1.6-1.8 m.) That was 4-12 inches (10-31cm.) taller than Neandertals. Their skeletons and musculature generally were less massive than the Neandertals. The Cro-Magnon had broad, small faces with pointed chins and high foreheads. Their cranial capacities were up to 1590 cm3, which is relatively large even for people today.
Origins of Modern Humans
Current data suggest thatmodernhumansevolved from archaichumans primarily in EastAfrica. A 195,000 year old fossil from the Omo 1 site in Ethiopia shows the beginnings of the skull changes that we associate with modern people, including a rounded skull case and possibly a projecting chin. A 160,000 year old skull from the Herto site in the Middle Awash area of Ethiopia also seems to be at the early stages of this transition. It had the rounded skull case but retained the large brow ridges of archaic humans. Somewhat more advanced transitional forms have been found at Laetoli in Tanzania dating to about 120,000 years ago. By 115,000 years ago, early modern humans had expanded their range to South Africa and into Southwest Asia (Israel) shortly after 100,000 years ago. There is no reliable evidence of modern humans elsewhere in the Old World until 60,000-40,000 years ago,during a short temperate period in the midst of the last ice age.
