Female Birds Have Evolved Not to Sing?

Do you like to go outdoors in the morning, stretch your arms and listen to the birds singing?  Chances are the bird sounds come from male birds.  The "new" theory is that females evolved not to sing to protect their eggs and young from predators.  Is is only a theory of course.  There is no substantial proof.fairy-wrenIt is supported by one case say scientists.  The fairywren's clutch is considered the most likely to fall prey to a predator during breeding time because she sings constantly.  This is weak proof.  Birds like humans can choose to remain silent.  Why hasn't she evolved to remain silent when breeding?  There is a reason why fairy wren females sing while sitting on eggs.  They do so to "talk" to their mates, who answers back with a similar but slightly different song.
Quail eggs were planted in the field and a recording of fairywren chatter was played back.  We have a correlation folks: predators ate the eggs.  The more song played the more eggs were eaten.  Coincidence?  Perhaps!  If you bang on a can of pet food the dog comes running

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 stolen f

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/ . . . . . . . . . . . . . . . . . . . .
