Mutation Killed off the Woolly Mammoth

When a warmer climate spread across the world, mammoths were in deep trouble.  Melting snow together with predation by humans made the animals extinct.  There numbers dwindled to zero in 6,000 years.  A strange thing happened during this time.  The species tried to adapt and threw up countless mutations.  Most were destructive. | ▶ optimum not stories news. | mutations mammoths killed ◀ |
Extinction of woolly mammoth
The long dark coat, so good as insulation from the cold, became like satin and light could shine through it.  They got severe irritable bowel syndrome due to their loss of smell.    It stopped them from mating due to protein changes in the creature's urine.  | ▶ | australian| mutations ◀ |    

These changes are now known from two specimens in Siberia.  One on the mainland and another on a rock island.  It was the slightly later Wrangel Island specimen that had an over representation of genetic mutations. Those who want to save threatened species must now be careful. Inbreeding could bring about the mass genetic alterations and that kills off endangered animals. | ▶ | not. | mutations ◀        | ▶ | not | ◀ |

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...

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...
