Whales Sing a Different Song

It was believed that all whales spoke the same language like a bird species, for example, where all the birds have the same song. New observations show that whales sing different songs depending on where they live in the world.

Humpbacks on either side of the Indian Ocean do not sing the same song. Western Australian whales would not be able to "understand" whales in Madagascar. The two groups have been isolated from each other for a long time.

It would be expected that whales in the Northern Hemisphere and the Southern Hemisphere would differ, but the Indian Ocean whales are quite close to each other. The southern whales only have one similar song theme. A song is a series of themes.

Consuming More Tea and Coffee Prevents Diabetes - Doubtful

Claims about consuming certain things to improve health are way off beam. Every now and then supposed new research shows that if you eat this or don't eat that your health will improve.

Surely millions of regular drinkers who have diabetes are thinking, "Why me? Why have I got the disease&qu

Anthropology Has New Theory on Australian Aboriginals

Twenty thousand years later the world warmed up and Australia was cut off from its northern neighbors. This is the latest theory.  But when Europeans initially came to Queensland there were two types of native people. Each was a distinct genetic pool. One was like Papua New Guineans. The other was very slight and shorter. It is the latter that predominates today. Papua New Guineans Australian Aboriginals Some scientists still hold that there was only one move out of Africa. This is an unsustainable supposition. The doors for movement were always open. Australian Aboriginals were quite unique. It seems that they were the first to leave Africa. There is also the question of Tasmanian Aboriginals who were wiped out by arriving Europeans. There is no evidence of them now. They could not light fires. The flames had to be stolen f
