[/b]Jyera, what exactly does the phrase "in the forefront of evolution" mean? I get what you say about cultural evolution being a new thing (although I'd say it's not completley unique to humans, just a far stronger force in us than in other species).
Just looking to understand what the forefront of evolution could be.
Forefront literarily means ahead. Some will argue there is no such thing as being ahead in evolution. And that there are only fitness to survival. (not strong or better). I don't disagree.
But take note of the other words I used.
"Frog leaped" and "accelerated." , "brain ... as the vehicle"
"society as vehicle"
I feel human and their brain has reached and exceeded a critical-mass. Beyond which, any animal would have been able to use their brain in a fashion like human. Not just the mass, but also the way we use it.
So now the evolutionary changes start to happen in the brain. And human evolution accelerated in the mind. The new evolutionary trait are not physical. Eg. We grow new language, philosophy and even political beliefs to aids us as if we have new virtual distorted extra eye and limps. With our multiple invisible limps, we are growing to something like a FSM.
The other animal, have not reached that critical mass.
By the time they reach that, human would have had a run-away-headstart in terms of evolution. (and I don;t mean physical)
They are still racing car speeding on the runway of an airstrip, while our planes are already soaring. How fast can they catch up, when we hardly see any of them liftingoff, while we are speeding XXXkm/h in the sky?
Eos's End-of-line description of octopi and gorrilla does indicate that they have to have a breakthough evolution before they can leapfrog ahead.
Humans had done it. We're at the end of the line as a "racing car" and now we have "wings". Whether we are at the end-of-line as a "airplane" i'm not sure.
But I share the same kind of wonder, optimism and disgust as Eos have about our evolutionary status.
We creates our own ◊◊◊◊-hole, intimately called society, in which we swim amongst lies, diseases, drugs, malice, ignorance, compassion and evolve to be more and more adaptable. We're in much better shape than the animals.
