Ah, even the Krell, with their advance intellect, could never have foreseen creatures from the Id.

Not quite. Even Chuck believed in some mechanism of acquired trait transfer. Like, if you became burly and tanned from working in the fields, that should show up in your offspring. This would greatly compress the timeframe of species development (because billions of years is such a hard concept to grasp). Not sure if this suggested that an amputee should not have children lest they also be born shy on limbs. But it does bear on ...

... the fact that homo sapiens mental capacity has not changed significantly in the time that we have existed on this pebble. It is generally thought that if you were to be able to magically transport a cro-magnon baby to 1996, by today they would be basically indistinguishable from any other modern teenager in terms of how well they have done in school (whether some insurance company would have snapped them up for ads is another matter entirely). It would appear that human progress has largely been a matter of us struggling with each other to make things better: we have met the enemy and he is us.

Really? I had no idea he thought that. It's shown to be utterly wrong though. (Saying that. there was an article I read a while back showing how famine had changed the genetics in the sperm and eggs of people in eastern europe. Can't remember it, I'll try and find it) Just because he thought it doesn't automatically make it right. He admitted that he found it hard to believe the eye evolved through natural selection....but it has. I haven't actually read 'On the origin of species' but I'm told that a few of the unanswered questions in it have been answered by genetics.

I absolutely agree with this. I doubt we've increased in intelligence that much more than from 10,000 years ago (20,000? 50,000?). It's just that technology and knowledge is all built upon foundations laid by others in the past. As Newton said 'I have seen so far only because I have stood on the shoulders of giants'. It raises the question, if human intelligence has plateaued (let's say it has for the sake of argument), are there aliens on other worlds who's intelligence has also plateaued but at a higher level? Or a lower level? What does this mean for the speed of technological innovation and scientific understanding after the plateau is achieved? Clearly, there a million ways to get off topic

EDIT: I think I may have read your post wrong, Sydde. Are you saying that there was a theory around beforehand, thus showing my post about people being confused at the time to be false? Or are you saying that natural selection also has some lamarckian traits to it?

Sorry, it is a Wikipedia link to a sort of lamarckian-type theory Darwin favored, even when it was shown to be pretty shaky.

Yeah, I read the link. I had no idea Darwin thought there could be inheritable acquired characterstics, in whatever guise. It's very interesting. Either way, I originally used 'Origin...' (many a post ago) merely to illustrate the difference between evolution and natural selection.

Interestingly enough, this is an idea which has come back to life yet again in a different form with Transgenerational Epigenetics:

http://en.wikipedia.org/wiki/Transge...al_epigenetics

Darwin came before Mendel. Inheritance was under study throughout this time, but, not definitively understood until much later.
