Genetic Diversity Helps Fight Against Disease
The healthy existence of humanity will devolve if one thing is missed -- A team of researchers have succeeded in demonstrating experimentally that genetic diversity makes populations more resistant to disease. Why is it that animal and plant species throughout the world have different genetic variants within their particular species, even though it is supposed to be the "fittest" gene pool that survives? According to a common theory in evolutionary biology, it is to enable the species to respond more effectively to changes in the environment, such as the occurrence of disease. However, experimental evidence to support this theory is very difficult to obtain: After all, it is virtually impossible to observe how evolutionary trends develop in most animal and plant species -- their generation times are simply too long.
