Non-Human Primates had Brain Language Pathway

Until recently the earliest language pathway was believed to have originated 5 million years ago. However, it seems that the auditory system was evolving toward language in nonhuman primates 25 million years ago. This conclusion was reached after brain scans of humans, apes and monkeys.

The auditory system found in other primates is an evolutionary forerunner of the human language pathway. Therefore, there is a clear evolutionary path toward auditory cognition and vocal communication. Language capability is nascent in nonhuman primates.

Proof of early language development was there all the time but was never understood before. Analysis of the human brain shows a strong structure on the left side of the language pathway. The right side has changed from what it was in other primates: it has diverged into non-auditory parts of the brain.

It is now believed that the path to language capability began more than 25 million years, probably in preprimate animals. Brain scans of neurology patient is now underway to learn more about the evolved communication capacity in humans.

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...
