Brain power falling off?

Too bad voters in Guadalupe didn’t have a key piece of information before denying those library funds. As it turns out, humans may need all the intellectual help they can get.

Scientists have revealed that modern human brains are smaller than the ones humans had 5,000 years ago.

One might assume that because technology has facilitated the shrinkage of computers from room-sized to palm-sized, while becoming smarter, the human brain might be following a similar path.

Maybe yes, maybe no. Researchers can’t really explain the smaller-brain phenomenon, except to theorize it’s a function of better efficiency.

Good luck with that that. A study released last week suggests humans may be gradually losing intelligence, in large part because human brains have lost the challenge and demands of survival.

When humans were forced to adapt or die, their brains did a far better job of figuring things out. Today, some humans’ biggest challenge is trying to figure out the TV remote, or how to retrieve a text message.

The losing-intelligence theory isn’t universally accepted. Some scientists believe we’re actually much smarter, but in a more diversified way. In fact, the belief that we’re becoming dimwits is a distinctly minority opinion.

There is another possibility, that smart phones and match-box-sized computers are doing all the work for us, so our brains are free to seek new knowledge — such as one might find on “Housewives of Orange County” or “Dancing with the Stars.”
