Anthropologists Puzzle Over the Hobbit of Flores Island

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.
A Human compared to the Hobbit of Flores island in Indonesia
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 about the Hobbit is how did it get so close to Australia?
There must have been an exodus out of Africa much like the one that occurred to humans. We obviously were not the first upright ape to spread out widely from its source. Anthropologists have recently accepted the hypothesis that Man lived alongside other bipedal apes. The chain-like evolution of the ape family is now in the waste paper bin.

Platypus Ancestor Found

When a platypus specimen was first viewed in England it was a sensation, Many people including scientists said that it was a fake: it was a combination of parts from other animals. However, it did exist in the Australian niche where it evolved.

I should be noted that this was in an era when the English were still struggling with Darwin's theory of survival of the fittest. The majority of the population still believed that God created Man. The Garden of Eden was foremost in their minds.

Today, the platypus' existence is accepted without question. There has not been a lot of fossil evidence about how it came to be. Recently, this gap has been filled by a fossil of an ancient duck-billed marine reptile. Like most fossils which illuminate family trees it was found in China.

Eohupehsuchus brevicollis lived 248 million years ago. Only two other examples of this creature have been brought to light, both in other parts of China. Like the platypus it was small for its time. It lived in an inland sea.

While its body proportions were different from the platypus, clear parallels can be seen: a broad body, no teeth and paddle arms for swimming. Eohupehsuchus brevicollis had a very short neck like the platypus. The fossil is an excellent specimen for research being nearly complete. It has evidence of being attacked, though it did survive this and lived for some time afterwards. The animal was a survivor of the mass extinction of the Permian era 252 million years ago.

Dinosaurs Found in Australia - What is Fact?

Australia is a very old continent. It seems the ancestors of Tyrannosaurus rex lived here. A hip bone has been found that dates to 110 million years ago which is 40 million years before T.rex roamed elsewhere on earth. Until now it was believed that T.rex only lived on northern continents.

Many of the things stated as fact by scientists are indeed just matters of faith until they are "proven" otherwise. Scientists argue about when dinosaurs developed feathers and why. They claim that birds today are direct descendants from dinosaurs. This is like saying humans are descended from dinosaurs. Much evidence points to birds having a line of descent completely separate from dinosaurs.

The same rings true with the Hobbit people of Flores Island. Some scientists will not accept that people different from humans survived until 18,000 years ago alongside humans. Neanderthals lived until 50,000 years ago, so why not another type of human? Science is much like religion. What is just theory is put forth as fact. Ah, the dangers of religion - and science!

Humans Did Not Kill Off Megafauna

During the Middle-Late Pleistocene, one million to 10,000 years ago, more than 50 species of animal disappeared, the last to do so 46.4 thousand years from the present. The reason for the demise of the giant creatures is hotly debated. Some scientists claim that the spread of Man across the globe was the cause. This is suspect, however, because there were so few of them. Killing the odd animal would not have made a significant impact.

Many believe that the end date for megafauna is incorrect. As stated above, the theory that humans killed them off by definition means that people and animals lived side-by-side for a considerable time. Evidence in Australia certainly points to this - 13 species of large animals were here on human arrival. Moreover, the people mainly relied on subsistence strategies for food. Their weapons were not very efficient. A boomerang is highly inaccurate and the range of a spear is limited.

Megafauna died out over a long period of time, not all at a specific date. Species lingered on in many regions. Just assuming that humans killed them is a mistake and diverts from the discovery of why the large animals became extinct. This was a time of extremes in climate. Perhaps a series of wild swings in climate gradually reduced their number to the tipping point where reproduction did not take place.

Gamburtsev Subglacial Mountains' Mystery Solved

The mystery of how the Gamburtsev Subglacial Mountains in the Antarctic was formed has been solved. The range is at a high elevation and was only discovered in 1958. It is buried under 3,000 meters of ice.

A group of scientists used aircraft with magnetometers, gravity meters and ice penetrating radar. They found that the mountains had been there for a billion years. The range spreads out in a 1,800 long earth fracture reaching from the eastern Antarctic to India.

This region of the Earth has been relatively free of tectonic activity. A billion years is short in tectonic terms, so the mountains have sharp edges not greatly worn away by water, wind and snow.

The rift system also contains the largest subglacial lakes on the Antarctic continent. Before animals roamed the Earth micro-continents collided to form the thick crustal root on which the mountain range stands. As the mountains eroded the root was preserved, frozen by the bitter cold. When dinosaurs existed 250,000 years ago supercontinent Gondwana broke away, the crustal root warmed which pushed the mountains even higher. Less than 50 million years ago the Antarctic ice formed over the range protecting it again.
