In a new paper published by Science, Alexey Kondrashov, Professor of Ecology and Evolutionary Biology at the University of Michigan, along with the co-authors of the study, have proposed that a ...
Assisted reproductive technologies (ART) can bypass female-modulated sperm selection (top of figure) that ensure that genetically compatible or competent sperm are used for fertilization. ART can also ...
Chemical signals at the most critical moment for new life in mammals -- when sperm meets egg and attempts fertilization -- evolve rapidly in a process driven by positive Darwinian selection, according ...
In natural populations, the mechanisms of evolution do not act in isolation. This is crucially important to conservation geneticists, who grapple with the implications of these evolutionary processes ...
In dense and repetitive text, Rothman (Life Beyond Molecules and Genes), a retired physiologist from the University of California, San Francisco, attempts to point out a major flaw in evolutionary ...
New evidence suggests that natural selection is leading women to have their first child at earlier ages. This is shown to be an inherited evolutionary change that is taking place despite the influence ...
