New Way to Kill Cane Toads

It has recently been discovered that the way to fight the intrusive cane toad in Australia is to fence off all waterholes and dams. Without water they die. Another method has also been identified. A chemical that is in the toad itself is used against it. Tadpoles contain this chemical that kills toad eggs on contact. Those that survive grow at a slower rate than normal, so they are more vulnerable to predators.

The chemical is harmless to native species. Ways of implementing this strategy nationwide need to be developed, but this is only a matter of time. The pest has just reached the far west coast of Australia, leaping its way across the whole country.

West Australians are on search and destroy missions into the night. Queenslanders gave up on this years ago at it had no impact on their numbers. The fight continues.

Anthropology Has New Theory on Australian Aboriginals

New theory on Australian Aboriginals - Anthropology. Australian Aboriginals split from Eurasians and moved south into the dry continent. 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 stol...

Natural History Museum Human Evolution Gallery

 The Human Evolution gallery at Natural History explores the origins of Homo sapiens by tracing our lineage back to when it separated from that of our closest living relatives, the bonobos and chimpanzees. Around 200,000 years ago, Africa was where modern humans developed. They have smaller faces and brow ridges, a chin that is more prominent than that of other ancient humans, and a brain case that is higher and more rounded. Modern human fossils from Israel (around 100,000 years old), Africa (around 195,000 years old), and Australia (around 12,000 years old) are among the casts on display. These fossils demonstrate that typical characteristics of modern humans evolved over time rather than emerging fully formed from Africa. They also suggest that at least two waves of people leaving Africa may have occurred, one about 100,000 years ago and the other about 60,000 years ago. We are all descendants of those who left during that second migration wave outside of Africa. Source: Natural...
