Can ToE explain human Brain development?

This is of course incorrect. Why should this assertion be so? Your implication is that we possess something special that other animals do not have.This is true: but many animals have something that is unique to them. For humans it is the abstract cognitive ability of our brains.For elephants it is their dexterous manipulative trunk.For spiders it is their ability to construct cunning snares out of silk.Can you see where I'm going with this? The fact that humans have abilities at a different level to other animals (for better or worse, remember) is no challenge to ToE. Our cognitive ability allows us to plan for the future and anticipate complex situations that are yet to happen; we can predict what is possible.If we can predict a negative situation and avoid it we improve our chances of survival.I'm sure you can fill in the dots from here.Ever worried? Ask your self what worry is; it's a negative prediction about the future. Our brains are wired to work this way because if we are worrying about lions in the long grass we will avoid the long grass and stay alive long enough to breed.This is so because only the cautious worry ridden humans of pre history survived to breed (as their less cautious comrades got picked off through the generations).So there you have it: being clever is as useful to survival as being able to build webs or detect sonar or generate bioelectricity or fly or inject poison or track by scent or............

What makes you think that this is true? By this logic the Mink is too successful as well because it 'too good' for it's environment (when it was accidently introduced into the UK by do gooders).By that logic the cat and the rat are 'too good' at what they do (when introduced into Oz).The point is that our brains did not evolve towards a specific level of capability.You've been told before evolution has no 'aim'. Once a trait is selected for it will keep being selected until it is no longer of benefit for the organism in question.We cannot be 'too good' because the is no point in which evolution stops unless one removes the selection pressures.A bit it off topic but worry is what I'm currently researching into so here are the bare bones facts:Worry is a verbal thought process.
Worry is a deliberate act selected to reduce ANS arousal.
It is anticipatory and negative.I would be very surprised if non verbal animals worry in the way we do, but if some animals in fact do have a language then I guess they could worry like we do. While this is true it is only true for individuals. For populations it is not true. This statement hold equally true of humans in general. When I was a lad we would pull wheelies in front of the girls and climb up barnyard walls bash the hell out of each other with sticks with the sole intent of impressing the girls.Take this habit into adult life and you become what text books often call a 'fanny magnet'.

You can't talk in terms of need!We did not evolve great memory because we needed it!The fact that we have an 'almost unlimited capacity to recall' is because our brains make new connections when we memorise something new. This is an inevitable consequence of how our brain evolved, not why our brains evolved!Edited by Larni, : Punctuation
