Why Do Humans Grow Up So Slowly? Blame the Brain

Posted by Unknown on from the brains-considered-harmful dept.

sciencehabit (1205606) writes Humans are late bloomers when compared with other primates — they spend almost twice as long in childhood and adolescence as chimps, gibbons, or macaques do. But why? One widely accepted but hard-to-test theory is that children's brains consume so much energy that they divert glucose from the rest of the body, slowing growth. Now, a clever study of glucose uptake and body growth in children confirms this 'expensive tissue' hypothesis.

    Why don't you get it? CORRELATION DOES NOT IMPLY CAUSATION!

    Just because there is a correlation it DOES NOT mean that there is causation! This is not difficult to understand, so why are you having so much trouble comprehending it?
