If evolution is true then how the unused part of the brain has been created?

Answer 1

When people say that however many of the cells in our brain are not used... they are talking about our glial cells which are used for support and nourishment of our neurons (brain cells which actually carry out brain functions). We use all of our brain... to say we don't is inaccurate and doesn't take into account the function of these "useless" portions.

Answer 2

Firstly, we don't know that any part of the brain is actually unused. Secondly, it would be more appropriate to ask why introns exist in the genetic material, since it takes energy to create this material which is basically unused. The answer gives an important clue as to how evolution works: the introns were exons in some previous generation, and mutations turned them off. Additional mutations from time to time turn introns (or portions thereof) back on, causing further variation. Back to the brain for a moment, if there is unused material, it was either created by a mutation that also created something useful, or by a mutation that abandoned the use of some part that turned out to be unneeded for survival.

Answer 3

There is no "unused" part of the brain, except for parts that are damaged (by toxins, drugs, trauma, etc.). If evolution can not be used to explain all brain parts, how would religious belief and "divine design" explain the creation of "unused" parts of the brain?

Answer 4

The "unused part of the brain" theory is false.

We just dont have the science to be able to know what it all does.

Perhaps this "unmeasured" part of the brain actually proves evolution? Maybe this part of the brain is still developing into something we can not possibly guess at, the next step in evolution

and so you know I AM a Christian (Mormon) and accept all possibilities!

Answer 5

There is no unused part of the brain, so the quesion is irrelevant.

Here's a basic-level debunking of the myth that large parts of the brain are "unused".

Answer 6

There is no unused part of the brain. That is an urban myth. While for the people who repeat that myth, it's probably true, the rest of us happily use all of our brains.

Answer 7

There is no such thing as an "unused" portion of the brain. That's a myth. However, lots of people leave much of their brain dormant for most of the time.

Answer 8

We dont know much about how the brain works, so it might have some function, which we dont know about. Evolution theory has been proven quite exstensively, so i believe more firmly in that then in nething the current state of neuroscience produces.

Answer 9

And whose fault is it that most of your brain is unused ?

Answer 10

No every part of our brain serves a purpose.
