Dr. Tishkoff\u2019s team interprets these divergent DNA sequences as genetic remnants of an interbreeding with an archaic species of human … the geneticists estimate that the archaic species split from the ancestors of modern humans about 1.2 million years ago.<\/p>\n

(NYT)<\/p>\n<\/td>\n

Homo sapiens vampiris<\/em> was a short-lived Human subspecies which diverged from the ancestral line between 800,000 and 500,000 year BP … Vampires and humans never achieved complete reproductive isolation.<\/p>\n

(BSE)<\/p>\n<\/td>\n<\/tr>\n

Genetic calculations suggest the interbreeding took place between 20,000 and 80,000 years ago.<\/p>\n

Two of the hunter-gatherers in the study, the Hadza and Sandawe of Tanzania, speak click languages and carry ancient DNA lineages that trace to the earliest branchings of the human family tree.<\/p>\n

Jukka Sarasti … clicked to himself when thinking. This is thought to hail from an ancestral language, which was hardwired into a click-speech mode more than 50,000 years BP. Click-based speech is especially suited to predators stalking prey on savannah grasslands. The Human language most closely akin to Old Vampire is Hadzane.<\/p>\n

Richard Klein, a paleoanthropologist at Stanford University, said the new claim of archaic and modern human interbreeding \u201cis a further example of the tendency for geneticists to ignore fossil and archaeological evidence, perhaps because they think it can always be molded to fit the genetics after the fact.\u201d<\/p>\n

The archaic sequences make up only 2.5 percent of the genomes of the living hunter-gatherers…. They may, therefore, have no effect on a person\u2019s physical form, which could explain why the fossils show little sign of them…<\/p>\n

Due to the relatively brief lifespan of this lineage, these changes were not extensive and overlapped considerably with conspecific allometries; differences become diagnostically significant only at large sample sizes (N>130) …<\/p>\n

While this provoked radical neurological and behavioral changes, significant physical changes were limited to soft tissue and microstructures that do not fossilise. This, coupled with extremely low numbers of vampire even at peak population levels (existing as they did at the tip of the trophic pyramid) explains their virtual absence from the fossil record.<\/p>\n

(BSE)<\/p>\n<\/td>\n<\/tr>\n

…we identify numerous loci that harbor signatures of local adaptation, including genes involved in immunity<\/strong>…<\/p>\n

(L)<\/p>\n<\/td>\n

Since cannibalism carries with it a high risk of prionic infection, the vampire immune system displayed great resistance to prion diseases, as well as to a variety of helminth and anasakid parasites.<\/p>\n

…metabolism<\/strong>, olfactory and taste perception, reproduction, and wound healing.<\/p>\n

Extended periods of lungfish-like dormancy (the so-called “undead” state)\u2014and the consequent drastic reduction in vampire energetic needs\u2014 developed as a means of redressing this imbalance. To this end vampires produced elevated levels of endogenous Ala-(D) Leuenkephalin (a mammalian hibernation-inducing peptide) and dobutamine, which strengthens the heart muscle during periods on inactivity.<\/p>\n
