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 n...

Write this down mister Neanderthal. Well, they weren't that good but they did do rock art. The oldest avenue of recorded expression for upright man consists of patterns in red ochre on cave walls in Spain 64,000 years ago done by H. neanderthalensis. ⎳ neanderthal go years at australian be before to neanderthals in created or humans | neanderthals of created| ⎳ Oral spray painting of the hand was also found. This was a step forward in using the body itself as a tool. Humans did not teach them. It seemed to ad hoc experimentation. They did it on their own. Yes, Neanderthals did it first.   ⦿ neanderthals us created at rock of art it before oh humans | if blog for an rock he neanderthals is created to rock a art | ⦿ Significantly, they painted with a system of dots, much like Australian Aborigines. Moreover, sea shells were used as "paint" containers. The carapace were dated at 115,000 years. This theoretically pushes paintings far, far back.   ⧗ oh neanderthal u...

Vanuatu ancestors were from Taiwan and the Philippines. A discovery has sent shock waves through anthropology. The ancestors of Vanuatuans were put in the pot of Pacific Islanders. People of this island do not look like Asians. However, DNA tests on the oldest skeletons found show that the island's first arrivals came from the Philippines and Taiwan only 3,000 years ago. It seems that Australian Aboriginals and New Guineans were not keen to venture out onto the high sea, though Pacific islands were much closer to them than it was for Southeast Asians. Scientists say Papuans moved their later to produce the modern Vanuatuan gene pool. There is a problem here. Combining the facial features of say Filipinos and Papuans does not produce modern Vanuatuans.  There was earlier movement westward across the large ocean of people from South America. Pacific islanders of South American descent obviously arrived in Vanuatu at some time. ◆ Antrhopology by Ty Buchanan ...

Anthropologists say the Hobbit of Flores did exist. The naysayers have had to accept that the Hobbit discovered on the island of Flores in Indonesia did exist. They survived until about 15,000 years ago. Anthropologists should have taken notice of local folklore. Stories were handed down to the present about tiny "people" raiding food crops at night. Remains have been closely examined by scientists. It was a tiny version of Australopithecus a human predecessor which lived in Africa from 4.5 million to 2 million years ago. The creature grew to small stature because it was trapped on an island. Short legs made it hard for them to walk but they did nonetheless - large trees do not grow on Flores. Despite having a small brain Homo floresiensis  developed stone tools to a complexity equalled only by humans. Its teeth were closer to human teeth than any other ape-like pre-human. This accounts for its naming as homo rather than Australopithecus . The real mystery ...

Bush fires are natural in Australia. Far from being a curse, they benefit the environment and wildlife generally. Of course this has to be qualified by houses being destroyed and injuries to people. Aboriginals have been intentionally lighting fires for thousands of years. Actually, it has a positive impact on kangaroo evolution. A fire promotes an increase in kangaroo numbers. To get the greatest benefit the best time for a burn-off  can be identified. Human subsistence is crucial in managing this. It compliments the ecosystem. Modern farming is detrimental to the way wildlife functions. The system is thrown off-balance. Stopping the burn-off and mono cropping changes everything. Australia needs more burning, not less. Authorities are following the wrong policy. Leaving native trees to grow tall can only lead to eventual disaster as a massive fire results as time passes. Managed fires provide more food for animals as new shoots appear. Animals can also h...

Eons ago ancestors of whales made a major leap forward in evolution of their mouths. Whales living today can filter-feed in large amounts because the lower jaw is flexible in movement. Ancient fossils such as Janjucetus hunderi do not have such a mobile lower jaw. The development of this attribute probably initially evolved to consume large living prey. It began with a wide upper jaw and normal teeth - no comb filters. Erich Fitzgerald from the Museum Victoria in Melbourne has created a family tree showing whale evolution. The way whales feed is unique. It is believed that sucking when feeding still takes place, a left over from the days of the wide upper jaw. A big question is why whales went back into the sea in the first place. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http://www.technorati.com/blogs/ http://adventure--australia.blogspot.com . . . . . . . . . ...

Eye Size is not accidental. It is determined by evolutionary factors. This is not so obvious today because in the twentieth century people moved to new countries in regions quite different from their place of origin. Eye sockets were measured from 55 skulls of native people throughout the world. The skulls were in museum collections from the 1800s. Large eyes were synonymous with large craniums. The native population of Micronesia had the smallest eyes. Scandinavians had the largest. This is contrary to the belief that Africans have the largest eyes. Eyes size is affected by the length of day and sun brightness. Bigger craniums were due to more brain allocation to sight. It did not make people smarter. This finding must mean that being able to get about in low light was important for survival. Features important for survival until the age of reproduction are carried on to later generations. Some things, however, can remain in a population if they affect life after puberty, ...

Dinosaur metabolism was not only higher than reptiles, their bodies ran at a faster rate than mammals. Analysis of tiny holes in their bones shows that they pumped a lot of blood through their bodies. So scientists have been wrong for a long time claiming that dinosaurs were slow moving creatures who relied on the sun to get going each day. Tests across a wide range of dinosaurs, big and small, confirm they moved around with ease. Some scientists have accepted the hypothesis that dinosaurs were not reptiles. It makes one wonder how many other things we are taught at schools are totally wrong. New evidence for upright walking of apes goes back more than four million years to an animal with feet designed to climb trees. Their hips are clearly designed for walking upright. And for decades we had been told a special foot design was necessary for bipedal walking. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/Adventu...
