Hibernation Genes Means Pandas are Born Premature

One evolved feature in an animal can affect another feature. Of course, the environment is the main factor in determining which feature wins out. Some animals have developed hibernation to survive harsh winters, but this can affect foetal development.

Bears in particular are born very small because of a short pregnancy due to hibernation. Pandas have this trait even though they do not hibernate. They carry the genes for hibernation, though it is not expressed.

Oddly, panda cubs are born weaker than other bears. Adult pandas are 900 time larger than their newborns. This ratio is higher than other bears, though polar bear have a ration of 400:1. Mammals generally have a ratio of 26:1 overall.

It seems that baby pandas are born prematurely as the norm. Their bones are underdeveloped. This is making survival of the species difficult. Without help from humans the species would have become extinct.

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...
