I must admit--in all humility--that many of us in the biosciences knew this for years.

"Gene expression is the process by which genes are turned on or off. Not all of the estimated 30,000 genes in humans are activated at the same time in every cell. "We think gene expression is a major part of what separates chimps and humans," said Kevin White, an associate professor of genetics, ecology and evolution at Yale University in the United States." Turning on or off various genetic subroutines (i.e. genes) is also called "better programming."

Looking at those quad walkers from Turkey got me thinking. People and animals that live in the dirt with their hands are probably ingesting a goodly amount of lead with all it's dumbing down properties. Could people and chimps and the like be the victims of poor hygiene as the principal reason for their retarded development? As man went upright and erect he probably gained many many IQ points as a result of not poisoning himself constantly. hmm.

Beer. It was beer.

I was thinking maybe a better view of what was trying to sneak up on him.

Yes, my first reaction was, "Duh!" However, it's always good to get solid confirmation.

How do they know what genes were doing 65 million years ago?
To: Pharmboy
I must admit--in all humility--that many of us in the biosciences knew this for years. Rather obvious yes -- but I hate these PR releases. They really distort and lionize.
As far as gene regulation, the transcription, yes, but it's not at the transcription factor level. Everything is indicating it is chromosomal and epigenetic much more than any mutated genes.

The researchers do not know what caused the shift in gene expression in humans but they suspect it could be due to changes in the environment, the acquisition of fire and a preference for cooked food. Does this say that environmental changes could actually be the cause of rapid evolution, rather than rapid evolution being a response to changes in the environment?
Of course fire and cooking are man made changes in the environment. Don't know what different that might make, but certainly it seems there is at least a possibility for some kind of positive feedback mechanism there.

What changes in the environment could it be?
Both man and chimp live in relatively same environments.
Acquisition of fire? Fireflies have bioluminescence,
did that stimulate them to become sometin' else?
This sounds quite "Lamarckian" i.e. an organism adapts
to one sort of behaviour because one of its ancestors
did it..like a proto-giraffe eating leaves off of the top of a tall tree, and its offspring get longer necks....I believe "Lamarckianism" is pretty well discreditied in most
biological circles...no?

More like 96.2% difference last I heard.It all depends on how you measure it. Which makes discussions about these numbers rather confusing.

Not to worry. According to the brainy scientific materialists, this means that any monkey can become a liberal if given enough time and creature comforts.

Hey--he's a frickin' chimp! He can't read the NRA safety guidelines (but I will tell him next time we go shooting together).
