While it is already well known that women are more likely to conceive twins during the middle of their reproductive life, the research findings, published today in Nature Ecology and Evolution, explain the evolutionary history behind this phenomenon. Associate Professor Joseph Tomkins from our School of Biological Sciences said the frequency of double ovulation, which is the release of two eggs during the same month of a menstrual cycle, had evolved to maintain female fertility. ΓÇ£Our work suggests that the probability of releasing two eggs increases as women age due to an evolved response to the age-related decline in embryo viability,ΓÇ¥ he said. ΓÇ£Using simulated tests, we were able to show that in ance
