The scientists say the monkeys represent an important step in how researchers study human disease.

"To mention an example, we have found that about eighty percent of all genes that are known to be associated with human disease have a counterpart in frogs.

Warren says now that researchers have a map of the zebra finch genome, they can carry out experiments to identify which genes in the finch's brain are most critical to hearing and producing song - and by extension, which genes may play a role in human speech disorders, like those related to stuttering, autism,and Parkinson's disease.

It seemed to me also that every living African, whether in good or ill health, is prey to many enemies of health that would interact one upon the other in many ways within one human body, Critics feared if President Mbeki appeared to doubt the link between HIV and the disease, people would not practice safe sex and use condoms.
