Gene Research Supports Ancient Human Genetic
By James Donahue
A researcher at the prestigious Howard Hughes Medical Institute
said he found genetic evidence that the human brain evolved at an “extraordinary speed” when compared to the brains
of other animals.
A paper, published in 2005 by Professor Bruce Lahn, a teacher
of human genetics at the University of Chicago, inadvertently supports a theory that humans on Earth are genetically altered
apes carrying DNA planted by possible alien intervention thousands of years ago.
Lahn does not suggest DNA manipulation, but he notes that
“evolution has been working very hard to produce us humans. Our study offers the first genetic evidence that humans
occupy a unique position in the tree of life,” he said in an interview with the UK Guardian.
The story said that Lahn’s research, published in
the journal Cell, “suggests that humans evolved their cognitive abilities not owing to a few sporadic and accidental
genetic mutations – as is the usual way with traits in living things – but rather from an enormous number of mutations
in a short period of time.”
Evolutionary biologists argue that humans evolved in the
same way as all other life on Earth. They say mutations in genes from one generation to the next occasionally produce new
adaptations to a creature’s environment. In other words, those best adapted to the environment are more likely to survive
and pass their genes to the next generation.
This can be seen as a “survival of the fittest”
rule in nature. The stag with the larger body and best rack of horns wins the doe and together they become parents of a better
and healthier breed of the species.
A problem with the human evolution theory has been the mere
size of the brain at a certain point in the historical record. Usually animal’s brains grow in size as the animals get
larger. But the humanoid brain suddenly became very large and his cognitive skills increased almost overnight.
In humans, Lahn reports, “the relative size of the
brain does not fit the trend – our brains are disproportionately big, much bigger even than the brains of other non-human
primates, including our closest relatives, chimpanzees.”
Lahn continues: “Human evolution is, in fact, a privileged
process because it involves a large number of mutations in a large number of genes. To accomplish so much in so little evolutionary
time – a few tens of millions of years – requires a selective process that is perhaps categorically different
from the typical processes of acquiring new biological traits.”
So how does the professor think such an amazing “accident”
could have happened?
His best suggestion is that the development of human society
may be the reason. He says an increasingly social environment demanded greater cognitive abilities from the participating
primates, thus forcing quick adaptations of the brain.
Could it be possible, however, that Lahn got it backwards?
It seems that larger and more developed brains would quickly bring about improved cognitive skills that resulted in more sophisticated
social behavior among the primates.
Something in our distant past caused humanoids to develop
very large brains. It is said, however, that humans have failed to learn how to utilize all of these magnificent brains. Has
something blocked us from turning on the full brain? Dare we suggest that the culprit may be ancient religious belief
systems that we refuse to shake off?
