In the study of humans migration, genomics and genetics really mean the same thing. Genetics is applied by genomics which analyses the structure of genomes. As well as migration much light has been shed on the origin of certain diseases. Alcoholism has evolved in man because it was useful as a curative agent. It first occurred naturally from stored grain. Beer jugs were found with Stone Age people. Because it came from collected grains, alcohol and bread probably came into human culture at the same time, Alcoholism is a side effect of evolution. Benefits for Man outweighed this issue and anyway it could have started commerce via trade in beverages. Having a particular gene predisposes groups of humans to sickle cell disease. It was said to be a disease of black gene pools. However, white people can develop the condition if they have the gene.  There is a predisposition gene for type 2 diabetes, though this malady can be caused by diet and taking medications over a Long period

There is no way that Australia can prevent the extinction of some native animal species. Some can  be preserved with a national gene bank. Though a seed bank has already been set up to save native flora, nothing is planned for fauna. Present debate is centered on the loss of the northern and southern gastric brooding frog. If a gene bank had existed the frog would have been preserved. Australia has the worst record of native animals going extinct than anywhere else, not something to be proud of. Over 40 birds and mammals have disappeared since European settlement. Because government has been slow in allocating resources, private organizations have started gene banks. Indeed Taronga Conservation society Australia has stored genes from 20 native animals. This is far from adequate. Over 2,000 species need preservation. With the Taronga Conservation Society Australia, the Animal Gene Storage and Resource Centre of Australia at Monash University has a total of 100 endangered sp

It was thought that once the human genome was known "interpreting" how things work would be easy. However, this is not the case. The hereditary sequencing in our genes is not the only factor determining what we are and what we do. Only 3 per cent of human genes are actually involved in the "code". Little is known about what the rest do. It has been discovered recently that these "dumb" genes turn the letter genes on and off. They determine whether a cell becomes a brain or kidney cell, for example. There are 3 billion base gene structures, so there is a long way to go in understanding basic functions. At any one time 80 per cent of genes are active. Some are triggered by proteins. Others change into RNA that regulate letter genes. In regard to understanding human health, many bases just keep chromosomes quiet. A complicating factor is that genes overlap and have many end points - not singular. Over 4 million gene triggers have be found and they

Elephants aren't so different from woolly mammoths. DNA samples taken from mammoth hair shows they are much alike. Furthermore, there are indications that the mammoth population was so low toward the end that inbreeding took place. If the unique mammoth genome can be isolated it can be inserted into elephant DNA to produce a woolly mammoth. It has also been found that differentiation between mammoth was only minor, so that a disease could have easily wiped them out. Mammoth are more closely related to elephants than chimpanzees are to humans, which is about 99 percent. Evidence shows that there were two groups of mammoth. One group died out 45,000 years ago, the other 10,000 years ago. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http://www.technorati.com/blogs/ http://adventure--australia.blogspot.com . . . . . . . . . . . . . . . . . .
