Today, details of an important new way of determining proof of natural selection at the single gene level were published by the Public Library of Science (PLoS). The new statistical method will replace what is known as the standard neutral model, which many scientists say is less than ideal. According to them, the commonly used […]
Without doubt, the most intriguing evolutionary pressure of all is sexual selection. The how and why behind our choice of mates, and how evolution hasshaped our reproductive organs to achieve reproductive success, provide some fascinating insights into nature at work. An elegant demonstration of the contribution of sexual selection to brain evolution can be seen […]
