Search for Smart Genes

It seems the level of intelligence is determined by a few genes.  This must surely be too simplistic, particularly because specialists cannot agree on what intelligence is.  How do you compare memorizing general knowledge to the skill of knitting a fine jumper?  There are people who know just about everything about Australian rugby league, but this is their only area of expertise.

Finding will be made easier, apparently, by questioning the crowd rather that by brain scans, etc.  It is believed that the sought after genes affect brain size.  Considering that Neanderthals had larger brains than modern man, this seems to be the wrong hypothesis to start with.

While "the team" is sure they will find the genes they do admit that culture, education, health and upbringing can affect intelligence.  How are they going to filter these things out?  Obviously they can't.  Twenty one thousand subjects were catalogued and brain imaging was used.  Strangely, when the team was reaching its conclusions they discovered that another group was doing the same research with more people.  Now that is clever.

Albert Einstein's Genius Was Due to His Unusual Brain

Albert Einstein wasn't only a genius her was a very odd human being. His brain shows peculiar differences from the norm; it had many more folds than the average person. This gave the brain a greater surface area. It is like using a larger computer to do calculations. Upon his father's death in 1955, Thomas Einstein gave the pathologist permission to preserve the brain of Albert Einstein. It was photographed then dissected into 2,000 ultra-thin slices. The slices and slides of them were later distributed to researchers. The brain had more neurons and glia cells, well outside of the normal range; pariental lobes were unusual in the pattern of ridges and grooves. Einstein only had a brain of average size. The area controlling the tongue and face was larger, as was the region that involves attention and planning. Overall, Einstein's brain was complex. Many people think in words. He said his thinking was like a physical activity. If selection based on "healthy...

Natural History Museum Human Evolution Gallery

 The Human Evolution gallery at Natural History explores the origins of Homo sapiens by tracing our lineage back to when it separated from that of our closest living relatives, the bonobos and chimpanzees. Around 200,000 years ago, Africa was where modern humans developed. They have smaller faces and brow ridges, a chin that is more prominent than that of other ancient humans, and a brain case that is higher and more rounded. Modern human fossils from Israel (around 100,000 years old), Africa (around 195,000 years old), and Australia (around 12,000 years old) are among the casts on display. These fossils demonstrate that typical characteristics of modern humans evolved over time rather than emerging fully formed from Africa. They also suggest that at least two waves of people leaving Africa may have occurred, one about 100,000 years ago and the other about 60,000 years ago. We are all descendants of those who left during that second migration wave outside of Africa. Source: Natural...
