The establishments archaeological view, based upon the Out-of-Africa ideology, holds that Homo sapiens, modern man, evolved only 100,000 years ago, so races are insignificant, being too young. Today’s Amerindians entered America only 12,000 years ago. All this has been challenged by alternative archaeology: V. S. McIntyre, “Has Man Been in the New World for a Quarter Million Years?” The Barnes Review, January/February, 1998, pp. 31-36.
For example, the Hueyatlaco archaeological site is in the Valsequillo Basin, near the city of Puebla, Mexico. Excavation began at the site in 1962, and a wide array of stone tools was found. The team was led by Cynthia Irwin-Williams, and Virginia Steen-McIntyre had been associated with the site, first joining the team as a graduate student in 1966, and later in publishing results.
Hueyatlaco is highly significant, because geo-chronological dating of the artefacts, taken to be used by early humans, gives an age of 250,000 years before the present, whereas, as stated, orthodox archaeology takes humans to have only evolved 100,000 years ago. Since 1969 this research has been subject to scientific critique, but the objections have been systematically answered by further research.
Sam L. VanLandingham, “Corroboration of Sangamonian Age Artefacts from the Valsequillo Region, Puebla Mexico, by Means of Diatom Biostratigraphy,” Micropaleontology, vol. 50, 2004, pp. 313-342, gives a date of between 80,000 to 220,000 years BP, based upon an analysis of diatoms, microscopic unicellular algae, and in a more recent paper by him, “Use of Diatoms in Determining Age and Paleoenvironment of the Valsequillo (Hueyatlaco) Early Man Site, Puebla, Mexico, with Corroboration by Chrysophyta Cysts for a Maximum Yarmouthian (430,000-500,000 yr BP) Age of the Artifacts,” Nova Hedwigia Beiheft, vol. 136, 2010, pp. 127-128, give a likely maximum age of 430,000 years for the artefacts. This is completely inconsistent with the present Out-of-Africa hypothesis and standard view of the age of humans.
That is mainstream publications, but there is alleged in other more “radical’ archaeological publications evidence of human bones and artefacts dated to about 50 million years: M. A. Cremo and R. L. Thompson, Forbidden Archaeology (1993)! It does not take this more radical material to sink the mainstream view of the age of humans and origin of human races.
