Western Adults Have Chronic Raised Immune Responses

People who live in industrialized countries are physically weak when they are attacked by parasites, microbes and viruses. This is because children are increasingly being brought up in clean, sterile environments. If they are not exposed to these dangers as children they could die if "bugs" invade their bodies when they become adults.

In Ecuador, the Shuar people have a high childhood death rate, three times that in Western countries. However, as adults their immune systems are stronger. A group of Shuar adults was tested for inflammatory levels. Some had very low levels. Others had moderately high levels, below the chronic level, probably because they were in the process of becoming ill or had been sick.

Western adults have a generally high level of inflammation, constantly. There bodies fight "minor" infections all the time. Consequently, damage is caused to the body resulting in diabetes, cancer, heart attack and stroke. A Chronic level of inflammation can be a killer.

As susceptible Shuar children die, adults develop the "correct" immune response, only fighting back strongly against dangerous infections. Western adults' immune systems are not "tuned", as childhood minor infections are prevented. Basically, this is why people in developing countries may die in an epidemic, but they can survive an infective environment better than first world adults. Third world adults carry infections and have a mild immune response, when Western people would probably not survive living in such muddy conditions, particularly with the dirty water.

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...
