Banded Stilts Water Bird Always Finds the Water

As soon as inland rain arrives at Australian lakes, the banded stilt water bird makes its presence felt as well. It somehow knows that the rains have started from several hundred miles away.  This useful ability determines their way of life.

They don't hang about long. Rainfall will be limited so they move on to the next fresh rains spot. Birds were tagged with satellite transmitters. One bird flew directly to a saline wetland 1,000 miles away in two days. Another bird got there four days later, but the destination for both was the same.

Banded stilts do not have to migrate for improved feeding conditions. Their inbuilt system allows them to always find water. Why don't other birds do this? Obviously, evolution is "hit-and-miss". Animals develop abilities purely by chance. This is why evolution is successful. Animals move into niches that line up with their attributes.

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...

Beatboxing - Percussion Sounds of the Mouth

There must be a dearth of things to study. Scientists are now researching the odd sounds that people make. It may seem weird but its true. Those who can make odd sounds are called beatboxers. Scientists are interested in percussion sounds. These are expressed in Celtic, Chinese, North American and Indian cultures. Hip-hop is an area of great interest. A young "practitioner" had MRI scans done on his mouth while he created percussion sounds. The conclusion reached is that a lot of brainpower is involved in imitating percussion. It "is a small part of the larger puzzle," experts say. In my view it takes little mental concentration. Just put your tongue behind you top teeth a "tap" away. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://adventure--australia.blogspot.com/atom.xml http://www.technorati.com/blogs/ . . . . . . . . . . . . . . . . . . . .
