The researchers' latest findings support the "Red Queen Hypothesis."

-- Researcher Ma Zhanshan, in collaboration with Robin Taylor, a professor at Ohio State University in the United States, has found significant differences between the human intestine and reproductive tract bacteria in terms of "bacterial heterogeneity" and no significant differences within the reproductive tract system. The discovery supports the famous "Red Queen Hypothesis" in evolutionary biology.
said that male and female reproduction may seem to be very expensive compared to solitary female reproduction, but why the vast majority of higher organisms, including humans, have chosen the reforest strategy has been one of the important issues in evolutionary biology. The famous "Red Queen Hypothesis" in evolutionary biology and the "gender conflict" theory in sociology try to explore the evolutionary advantages of gender reproduction from the perspective of both competition and cooperation between the sexes. For example, the "Red Queen Hypothesis" states that sexual reproduction is beneficial for combating the attacks of highly pathogenic parasites (parasites, pathogens, viruses, etc.). However, "what is the relationship between non-parasitic organisms, especially host-friendly symblomic organisms such as intestinal bacteri, reproductive virlobis, etc., and reproductive reproduction?" "It's been a long time since.
Through the analysis of more than 2000 samples of human gut and reproductive tract virloids, researchers found that there are significant differences between human gut and reproductive tract virloids in terms of "bacterial heterogeneity", but within the reproductive tract system, the exact vaginal and semen virulent virloids are not significantly different.
, the researchers concluded that maintaining a relatively homogeneic bacterial environment within the human reproductive system should be conducive to conception (sperm-egg binding). There should be a co-evolutionary relationship between the human reproductive system bacteria and the host. The intestinal bacteria present in the digestive system did not choose to maintain homogeneity with the reproductive tract.
results were published online online in Oikos, an internationally renowned journal of ecology.
