In the course of evolution, sex has become one of the tools for combating ailments, as scientists have established. This kind of reproduction technique arose from bacteria that transmit dangerous diseases.
Human sexual reproduction has evolved under the influence of disease-causing microbes. Researchers have tried to answer the question of why, in the case of sexual reproduction, we observe noticeable evolution, while in asexual reproduction, which does not require a partner, the technology has hardly undergone any evolution. The theory is that the technique of sexual reproduction has improved due to the presence of various diseases. She needed constant evolution in order to respond in a timely manner to various pathogens, also undergoing evolutionary development.
Scientists at the University of Adelaide developed computer stimulation that supported their theory. The model helped answer the question of why most complex living organisms reproduce sexually. This question has plagued geneticists for over 100 years. Asexual reproduction, such as laying unfertilized eggs or pieces of oneself, is a much simpler method. It does not require searching for partners, spending a lot of time and energy.
Sex has fostered genetic recombination that has provided evolutionary benefits to many living things and humans. It makes it possible to recombine DNA between partners, creating many beneficial gene mutations. And they protect the offspring from diseases, which killed their distant ancestors.
