Did humans evolve in siberia?

Location of human tools found in Siberia
Russian academician Yuri Mochanov thinks so! He does not dispute that humans may also have evolved in Africa and, perhaps, Southeast Asia. And he has brought back some 4,000 stone tools collected at 15 sites in the Siberian permafrost to bolster his claim that Siberia, too, was a point of origin for hominids (see map).

"Molchanov's controversial evidence is indeed striking: a collection of chipped and flaked rocks that are clearly artifacts fashioned by humanlike hands and that he contends are 2.5 million years old -- plus or minus a half-million years.

"Remarkably, that same era marked the time when early human ancestors known as Homo habilis lived and left their remains in the tropical Olduvai Gorge of what is now Tanzania. Mochanov's collection of tools closely resembles the ones that anthropologists have long collected from digs in Africa."

All this contrasts strongly with the dominant view of hominid evolution, which cites warm, verdant African forests and savannas as our most likely place of origin. Siberia, with its -50 winters and fleeting summers, hardly seems conducive to hominid speciation. Mochanov's rationale is that this severe climate actually stimulated ancient hominids to create tools, fashion warm clothing, and build winter shelters -- these Siberian hominids had to evolve or perish!

In addition to the climate factor are two other problems: (1) The Siberian sites have yielded no hominid bones nor have animal bones of any kind been found; and (2) The dating of the tools is shaky. They cannot be radiometrically dated. Instead, Mochanov has had to rely on the tools' similarity to African tools of 2 million years ago, magnetostratigraphy, the decayed luminescence of the soil, and the ages of the strata in the 450-foot gorge of the Lena River. It goes without saying that other anthropologists are reserving judgment.

Nevertheless, Mochanov's Siberian discoveries have produced a magnitude-8 tremor in science.

(Perlman, David; "Russian Scientist Says Homo sapiens Has Arctic Origins," San Francisco Chronicle, January 17, 1994. Cr. J. Covey. A short summary of Mochanov's research appeared in: Stone, Richard; "Turning Out-of-Africa Inside Out," Science, 262:1963, 1993.)

Comment. It is odd that some other archeological sites with apparently very ancient tools, such as that at Calico Hills, California, are also devoid of hominid bones and radiometrically datable artifacts. A similar situation prevails at many North American epigraphic sites, where someone wrote copiously in ancient symbols but left little else to betray their identities.

Science Frontiers Sourcebook Project Reviewed in:


  • "A sourcebook of unexplained phenomena is therefore a valuable addition to a collection of scientific literature. William R. Corliss has provided this in the past with his source books of scientific anomalies in several subjects, and now he has provided it for astronomy. He has done an excellent job of collecting and editing a large amount of material, taken in part from scientific journals and in part from scientific reporting in the popular or semi-scientific press." -- "The Mysterious Universe: A Handbook of Astronomical Anomalies", reviwed by Thomas Gold, Cornell University, in Icarus, vol.41, 1980

  • "An interesting, systematic presentation of unusual weather [..] This book is recommended for a general audience" --"Corliss, William R., Tornados, Dark Days, Anomalous Precipitation, and Related Weather Phenomena, Sourcebook Project, 1983.", revieweed in Choice, September 1983
  • "..the science is necessarily somewhat speculative, but Corliss's symthesis is based on reputable sources." -- "Corliss, William R. (Compiler).

  • "Before opening the book, I set certain standards that a volume which treads into dangerous grounds grounds like this must meet. The author scrupulously met, or even exceeded those standards. Each phenomenon is exhaustively documented, with references to scientific journals [..] and extensive quotations" -- "Book Review: The moon and planets: a catalog of astronomical anomalies", The Sourcebook Project, 1985., Corliss, W.
