Conditions of primate life in Central China

Excerpt: The location of its discovery supports the once-controversial hypothesis that primates first evolved in Asia. When Beard first proposed that idea in the 1990s, he was “completely ridiculed,” he recalls. “Everybody knew that everything in primate and human evolution occurred in Africa.”

My comment: See Kamberov et al. (2013) and Grossman et al (2013): The fossil location suggests comparison to findings that indicate a climate change-dependent, diet-dependent amino acid substitution led to culture-driven sexual selection for pheromones associated with visually perceived phenotype in a human population that arose in Central China during the past ~30,000 years. Perhaps the timing of the climate change et al. is coincidental. However, their findings of epigenetic cause and effect conflict with mutations theory and the 55 million years time frame due to the fact that olfaction and odor receptors provide a clear evolutionary trail that can be followed from unicellular organisms to insects to humans.

For example, single amino acid substitutions result in species diversification in a variety of accepted animal models best exemplified in insects. Perhaps this primate was an insectivore and its adaptive evolution was nutrient-dependent and pheromone-controlled as is adaptive evolution in every other species on this planet. If so, it may not have taken 55 million years to evolve via ecological, social, neurogenic, and socio-cognitive niche construction and become a modern human. It seems more likely to me that the epigenetic tweaking of a few genes with large effects might have sped things up. Why wait for random mutations to somehow accumulate and cause something that appears to have been nutrient-dependent and pheromone-controlled across 5-10,000 years of wolf to dog differentiation?

If this little primate didn’t wait, the idea that other primates first evolved in Asia fits nicely with what Darwin told us about the ‘conditions of life’ required before natural selection and natural cooperation could proceed. Darwin’s ‘conditions of life’ are, of course, nutrient-dependent and pheromone-controlled.

About James V. Kohl 1308 Articles
James Vaughn Kohl was the first to accurately conceptualize human pheromones, and began presenting his findings to the scientific community in 1992. He continues to present to, and publish for, diverse scientific and lay audiences, while constantly monitoring the scientific presses for new information that is relevant to the development of his initial and ongoing conceptualization of human pheromones. Recently, Kohl integrated scientific evidence that pinpoints the evolved neurophysiological mechanism that links olfactory/pheromonal input to genes in hormone-secreting cells of tissue in a specific area of the brain that is primarily involved in the sensory integration of olfactory and visual input, and in the development of human sexual preferences. His award-winning 2007 article/book chapter on multisensory integration: The Mind’s Eyes: Human pheromones, neuroscience, and male sexual preferences followed an award winning 2001 publication: Human pheromones: integrating neuroendocrinology and ethology, which was coauthored by disinguished researchers from Vienna. Rarely do researchers win awards in multiple disciplines, but Kohl’s 2001 award was for neuroscience, and his 2007 “Reiss Theory” award was for social science. Kohl has worked as a medical laboratory scientist since 1974, and he has devoted more than twenty-five years to researching the relationship between the sense of smell and the development of human sexual preferences. Unlike many researchers who work with non-human subjects, medical laboratory scientists use the latest technology from many scientific disciplines to perform a variety of specialized diagnostic medical testing on people.
