Just started reading my latest issue of Archaeology magazine. “Stone Age India: Does evidence buried by a super-volcano redraw the map of human migration?” The volcano referred to is Toba, 74,000 kya. Apparently the culture dated to 77,000 kya under the ashes is similar to the culture dated 74,000 kya above the ashes. I have not yet read the whole article, but I think that might be evidence for the idea that some moved north to Central Asia, and eastward. Since the world population was pretty much decimated after Toba, it probably would have taken a while for population densities to have built up enough to support significant migration and deposition of remains.

Sunken Civ: You might want to make a separate post of this article for all our Catastrophism enthusiasts:

Interesting about the 5 root molars. My oldest son had to have all of his SIX wisdom teeth removed. Someone at the dental school said this is true of some Esquimos. Does anyone here have any information on this anomoly.

Sinodonty and Sundadonty

(From Wikipedia, the free encyclopedia)

Sinodonty and Sundadonty are two patterns, identified by anthropologist Christy Turner, for East Asia, within the "Mongoloid dental complex"[1]. The latter is regarded as having a more generalised, Australoid morphology and having a longer ancestry than its offspring, Sinodonty.

Sino and Sunda refer to China and Sundaland, while 'dont' refers to teeth.

He found the Sundadont pattern in the Jōmon of Japan, Taiwanese aborigines, Filipinos, Indonesians, Thais, Borneans, Laotians, and Malaysians, and the Sinodont pattern in the inhabitants of China, Mongolia, eastern Siberia, Native Americans, and the Yayoi.

Sinodonty is a particular pattern of teeth common among Native Americans and some peoples in Asia, in particular the northern Han Chinese and some Japanese populations. The upper first two incisors are not aligned with the other teeth, but rotated a few degrees inward, and, moreover, they are shovel-shaped; the upper first premolar has one root (whereas the upper first premolar in Caucasians has normally two roots). The lower first molar in Sinodonts has three roots (whereas it has two roots in Caucasians).

In the 1990s, Turner's dental measurements were frequently mentioned as one of three new tools for studying origins and migrations of human populations. The other two were linguistic methods like Joseph Greenberg's mass comparison of vocabulary or Johanna Nichols's statistical study of language typology and its evolution, and genetic studies pioneered by Cavalli-Sforza.

Today, the largest number of references on the web to Turner's work are from discussions of the origin of Paleo-Indians and modern Native Americans, including the Kennewick Man controversy. Turner found that the dental remains of both ancient and modern Indians are more similar to each other than they are to dental complexes from other continents, but that the Sinodont patterns of the Paleoindians identify their ancestral homeland as north-east Asia. Some later studies have questioned this and found Sundadont features in some American peoples.
