Uusi aivotutkimus paljastaa samankaltaisuuksia, mutta samalla myös eroavaisuuksia meidän ja simpanssien aivojenkehityksessä.

"In both chimpanzees and humans, portions of the brain that are critical for complex cognitive functions, including decision-making, self-awareness and creativity, are immature at birth. But there are important differences, too. Baby chimpanzees don't show the same dramatic increase in the volume of prefrontal white matter in the brain that human infants do."
"Those are the conclusions of a study reported in the August 11th Current Biology that is the first to track the development of the chimpanzee brain over time and to make the comparison to humans.
"One of the most marked evolutionary changes underlying human-specific cognitive traits is a greatly enlarged prefrontal cortex," said Tetsuro Matsuzawa of Kyoto University in Japan. "It is also one of the latest-developing brain regions of the cerebrum."
That built-in developmental delay, now shown to be shared with chimps, may provide an extended period of plasticity, allowing both humans and our closest evolutionary cousins to develop complex social interactions, knowledge and skills that are shaped by life experiences, the researchers say."

evokkien houretta.
"Matsuzawa's team made their discoveries by studying magnetic resonance imaging (MRI) scans of three growing chimpanzees from the age of six months to six years, when chimps reach pre-puberty."
En nyt tiedä, että onko tuollainen vajaan kuuden vuoden tutkimus kovin houretta.
Mitäs se "tieteellinen" kreationismi on saanut aikaan?
