End of Evolution?

We've invented penicillin, space shuttles, computers and even artificial hearts, among many other wonders. So where will human intelligence go from here?
The answer, if certain scientists are correct, is nowhere.
Mankind’s brain power has reached its peak and it is physically impossible for us to become any smarter, they say.

They claim that in order to become any more intelligent the human brain would need vast amounts of extra energy and oxygen – and we simply cannot provide it.

Cambridge University researchers have analysed the structure of the brain and worked out how much energy its cells use up.

Simon Laughlin, professor of neurobiology, said: ‘We have demonstrated that brains must consume energy to function and that these requirements are sufficiently demanding to limit our performance and determine design.
'Far-reaching powers of deduction demand a lot of energy because for the brain to search out new relationships it must constantly correlate information from different sources.
‘Such energy demands mean there is a limit to the information we can process.’
Other scientists claim that the brain’s ‘wiring’ or network of fibres linking different areas to one another cannot get any better.
They have found that the cleverest people have the best wiring, with messages carried very quickly between different parts of the brain.
But scientists claim that the wiring would need vast amounts of extra energy to become more efficient. As before, they say it is impossible for humans to provide this, therefore we cannot get cleverer.
Ed Bullmore, professor of psychiatry at Cambridge, where he specialises in brain imaging, measured the efficiency with which different parts of the brain communicated with each other.

He found impulses travelled fastest in smarter people and slower in those who were less intelligent.
He said: ‘High integration of brain networks seems to be associated with high IQ.
‘You pay a price for intelligence. Becoming smarter means improving connections between different brain areas but this runs into tight limits on energy, along with space for the wiring.’
Martijn van den Heuvel, assistant professor of psychiatry at Utrecht medical centre in Holland, who also studies how differences in the wiring of human brains affects IQ, said: ‘Increasing the power of the brain would take a disproportionate increase in energy consumption.
'It is risky to predict the distant future but it is clear there are tight constraints on intelligence.

Re: End of Evolution?

I know this is a massive mind fuck but evolution will make our brains bigger then or atleast make it more supplied to oxygen?

I know it's only a prediction here by scientists but it looks like they are trying to predict the future and because it's evolution it looks like they are trying to predict the far future which I think is near enough impossible.

Science I believe can not be predicted and I think we have to just go along with it and see what happens.

Re: End of Evolution?

these scientist are idiot. anything that happen to our environment will change our characteristic. is why evolution is consider to take random course and has no "design". these guy are examining detail and trying to refute entire process of adaptation, is like if I look at equation with non numeric variable and say "oh, since there is no number there is no need for operation" lmao.

Re: End of Evolution?

Human intelligence has nothing to do with evolution. Evolution, the theory pertaining to the development of life, will never end.

Re: End of Evolution?

I've always heard that humans use about 10% of their brains... if that's the case there is plenty of room for improvement.

Re: End of Evolution?

I think brain power is on the decline. A lot of computers and technology think for us and do a lot of work for us already.
