Further elaboration on part 1...

The biggest aspect I am trying to get across that simple postive genetic mutation acting independently of the environment leading to positive selection seems too basic - What I believe is that environmental stress created by the person (depression / cortisol etc) orientates expression / activates / changes that can be passed genetically onto offspring. Possibly they could be thought of as mutations, but these are directional mutations and not random. ...

Well, I've have had for a long time a sneaking suspicion that Darwinism was only partially responsible for evolutionary change.

As an example I have always considered the notion that if an animal wants a long neck enough then over time irrespective of biological replication its descendents (also wanting longer necks) will slowly change and gravitate towards that condition.

Now, the less open minded will think that is preposterous.

But what is Darwinism? ...

Interestingly (although in some way obvious) chromosomal differences come into play with se'x differences in brain function.

Rather than just an orientation solely determined by being bathed in se'x hormones you have hardwired differences right down to your XY or X'X architecture and how these are expressed.

I would expect over time with significant statistical study it will be possible to determine the parts of the human genome that are switched simply as part of the ...
