Is Tachytely in Human Evolution a sign of Guided Evolution

18 Sep

Is the phenomenon of accelerated evolution known as “tachytely” not to be considered a scientific phenomena of evolution because it does not comprehend that evolution is simply the unpredictable and haphazard nature of natural mutation rates and selection in any species? Do we therefore consider the speed of human progress as an accident of Nature. Or is it an indication that a supernatural process was responsible for guiding human evolution?

Prof Tattersall, from the American Museum of Natural History (AMNH) in New York, told the conference.’However you slice it, evolution within this [human family] has been very rapid indeed, I think it’s fair to say that our species Homo sapiens and its antecedents have come much farther, much faster than any other mammalian group that has been documented in this very tight time-frame’. http://www.bbc.co.uk/news/science-environment-19598980.

If one accept the theory that man evolved from the ape Homo habilis in Africa 2 million years ago, it spread throughout the globe very quickly indeed and this is only possible from pure evolutionary processes if its’s DNA changed to be able to live in just about any kind of climate and environment with total control over its predators. It seems that hominid (Homo) species since Homo ergaster in Africa has evolved much faster than would be expected from observations of mammalian species over the same time period, for example chimpanzees. Thus, Tachytely or accelerated evolution has indeed taken place as normally species take much longer to move out of their individual niches. It is an acknowledgement that there may be forces operating to produce mutation at predictable rates and on specific DNA sequences and on the accommodating population dynamics that would have equilibrated gene dispersal over both the ensuing Homo erectus and Homo sapiens descendents of Homo ergaster geographically that has guided human evolution.

If this interpretation is correct, do we in effect not have the suggestion of an unnatural (God’s) interference into the evolutionary process?
