Discover : Perhaps the course of humanbeing evolution is in one's hands from the foot

In the course of humanbeing evolution, how both hands become dexterous and quick, begin to make and use the stone tool? Perhaps Canadian researchers have untied this secret. They find, it is a pair of products whose foot evolved that the human hand evolves through studying. This result of study is published in the scientific periodical >.
Person in charge of research, Calgary university Campbell Luo LiAn says this should trace back to Charles Darwin >. Darwin considers the scientist of the relation while walking in stone tool technology and upright at first. Darwin thinks, the mutual independence of the two, take place in succession, walk and liberate hands in upright, make it can develop other function not to profit . Hand and foot change are developed similarly, one will manifest the by product on another one when changing.
While studying, Luo LiAn and colleagues measure the trick size of mankind and chimpanzee, hope that finds how the human ancestor's trick evolves. They find, the similar positions of hand and foot are concerned with closely. If a person's big toe is relatively long, its thumb is relatively long.
Luo sets up Ann to explain, thumb and toe are concerned with a close reason perhaps because they have the same gene and development " The blueprint " ,This one " L The blueprint " R Every change last foot.
Researchers set up mathematical model according to these data. Luo LiAn says : " We use the hand of simulation of mathematical model and evolution pressure of the foot. " Found finally, the foot change caused the hand resembling to change, especially at the similar position.
Luo LiAn says, these similar changes may be an important evolution backbone, make the human ancestor's sensitivity strengthen constantly, begin to develop stone tool technology.
Certainly this result of study has been queried by some experts too.
Anatomy professor Robin and Crompton of British Liverpool University says, this research is very interesting, but there are some questions . " L I it approves brothers of chimpanzee to be ' Human ancestor's hands and the foot one) Good model, perhaps the gorilla of Scotland lowland is more suitable. " He says.
Crompton say, human foot except size, a lot of biomethanics and function factor.
Hull, Britain - York anatomy professor Paul of medical college O'Higgins says : " The result of study is quite exciting. Without doubt, this will encourage researchers to study more. " (Source: Science and Technology Daily)
