'That' helps people evolve better

Sexual reproduction (having mating) helps people to evolve more effectively than breeding animals without mating, according to research by scientists at the University of Edinburgh (UK).

Scientists have discovered the combination of two parents' genes in sexual reproductive animals such as humans, fruit flies, rod bugs . that help faulty DNA can be replaced in a few generations. Meanwhile, asexual animals often have a higher risk of genetic diseases.

Sexual reproduction eliminates harmful DNA in future generations.

This is explained by the fact that individuals inherited healthy genes from parents tend to continue to improve and transmit DNA for the next generation. While weak individuals tend to die early and cannot reproduce.

Scientists at the University of Edinburgh conducted research in fruit flies to find out how their DNA was affected when DNA recombination did not occur. The results show that harmful DNA accumulates more and more in later generations.

The team said their findings are clear evidence to support the hypothesis that came out long ago that sexual reproduction has a long-term benefit to animal evolution rather than reproduction. asexual.

Dr. Penny Haddrill, head of research, said on the Daily Mail: 'In the animal world, individuals always try to breed. This is clear evidence that sexual reproduction helps animals adapt to eliminating harmful DNA. "
