ScienceDaily (Jan. 11, 2010) — The subtle but ongoing pressures of human

evolution could explain the seeming rise of disorders such as autism, autoimmune

diseases, and reproductive cancers, researchers write in the Proceedings of the

National Academy of Sciences. Certain adaptations that once benefited humans may

now be helping such ailments persist in spite of -- or perhaps because of --

advancements in modern culture and medicine.

" This work points out linkages within the plethora of new information in human

genetics and the implications for human biology and public health, and also

illustrates how one could teach these perspectives in medical and premedical

curricula, " says author Ellison, Cowles Professor of Anthropology at

Harvard University.

Ellison's co-authors are Stearns of Yale University, Randolph Nesse of

the University of Michigan, and Diddahally Govindaraju of the Boston University

School of Medicine. The research was first presented at the Arthur M. Sackler

Colloquium, co-sponsored by the National Academy of Science and the Institute of

Medicine.

Colloquium presentations described in the current paper include research

suggesting that:

* Autism and schizophrenia may be associated with the over-expression of

paternally or maternally derived genes and influences, a hypothesis advanced by

Bernard Crespi of Simon Fraser University.

* Maternal and paternal genes engage in a subtle tug-of-war well into childhood

with consequences for childhood development, as posited by Haig,

Putnam Professor of Organismic and Evolutionary Biology at Harvard.

* Humans may be susceptible to allergies, asthma, and autoimmune diseases

because of increased hygiene, according to Kathleen of s Hopkins

University. Without being exposed to intestinal worms and parasites, as our

ancestors were, our immune systems are hypersensitive.

* Natural selection still influences our biology, despite advances in modern

culture and medicine. Stearns found that natural selection favors heavier women

and reduces the age at which a woman has her first child.

In the final presentation of the colloquium, researchers called for the

integration of evolutionary perspectives into medical school curricula, to help

future physicians consider health problems from an evolutionary perspective.

" We're trying to design ways to educate physicians who will have a broader

perspective and not think of the human body as a perfectly designed machine, "

says Ellison. " Our biology is the result of many of evolutionary trade-offs, and

understanding these histories and conflicts can really help the physician

understand why we get sick and what we might do to stay healthy. "

Previous work in evolutionary medicine helped explain why disease is so

prevalent and difficult to prevent -- because natural selection favors

reproduction over health, biology evolves more slowly than culture, and

pathogens evolve more quickly than humans.

" I think that the main take-home point is that evolution and medicine really do

have things to say to each other, and some of these insights actually reduce

suffering and save lives, " says Stearns.

Out of respect for others I will refrain on giving my actual first response to

all this.

" I think that the main take-home point is that evolution and medicine really do

have things to say to each other, and some of these insights actually reduce

suffering and save lives, " says Stearns.

Nonsense.

A ficticious theory and a " science " taken over by drug companies are good

bedfellows. Unfortunately the result will be a continuation of rapidly

increasing death and sickness caused by the existing food, medical, and drug

cartel.

Paddling more complex ships down " deNial " will continue to increase the present

situation.

Glad the article includes organizations and individuals who may, in a more

englightened time, lead to proper prosecution.

Or the simple fact that humans put a bunch of toxins into their bodies....but

that's too simple isn't it? Much nicer to write up some fancy argument about

evolution along causing all this.

The one thing they fail to consider is that we have tampered with evolution by

injecting foreign animal dna and viral/bacterial dna into humans over the past

60-70 years. Along with toxic gene mutating chemicals. That's not

evolution....that's evil.
