Shrinking Intellect

I once read a science fiction story about an alien species of which the children were humanoid, and showed a lively intelligence and curiosity, but when they matured they grew roots and turned into non sentient shrubs.

I was reminded of that by a news item about the death of human brain cells as children mature.

I've often thought it sad that so many lively inquisitive children turn first into sex obsessed teenagers, and then into dull adults with very little interest in new ideas.

Apparently quite a lot of  brain cells die during pregnancy. That might explain the blinkered pre-occupation of mothers with their children. Their capacity to deal with other matters being restricted in favour of a concentration on successful reproduction.

We tend to see ourselves as the thinking species, vehicles of enlightenment in a world where other creatures are governed by instinct. Actually we are primarily successful breeders, outbreeding other species to the point where many are driven to the point of extinction.
