Society and High Intelligence Go Together

We have large brains due to social interaction.  In early societies culture meant things had to be remembered.  Another important function leading to large brains was tools use, though chimpanzees use tools.  The most intelligent people would inevitably become leaders and have the choice of mates, thus passing on their genes.

Intelligence and brain size are of course interdependent.  Animals such as dolphins and elephants have social structures.  They are also very intelligent.  Higher intelligence appears to be naturally selected for in any species.

Apparently, when society develops intelligence must increase otherwise an individual will be "put upon" by the smarter ones.  There is some evidence that really clever individuals tend to be disruptive to a society.  The naive are certainly at a disadvantage.

A thorn in the side of the above theory is that some highly structured societies are composed of small creatures with tiny brains.  Ants, bees and wasps are in this category.

New Species Found in Australia

An endangered animal, Antechinus, has two new members. Well, they have been there all along. A team from Queensland University of Technology discovered the Tasman Peninsula Dusky Antechinus (Antechinus vandycki) in south east Tasmania, and nominated the Mainland Dusky Antechinus   (Antechinus mimetes) . The latter was known to be in New South Wales and Victoria but it is now a species in its own right. The Tasman Antechinus is about 13 cm long with a short tail weighing roughly 90g. It is located in Port Arther, Tasmania. Under threat from clearing of trees it resides in state forest in fragmented groups.  Survival is precarious in the isolated stands. While uncovering new species is rare in developed countries, new ones are being found in Australia all the time. This is due to the low population density of people in inland Australia. Unfortunately, new species when found are usually in small numbers and under threat. Antechinus are not helping themselves...

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...
