Experiments explain why almost all multicellular organisms begin life as a single cell
Any multicellular animal, from a blue whale to a human being, poses a special difficulty for the theory of evolution. Most of the cells in its body will die without reproducing, and only a privileged few will ...

Life-history traits may affect DNA mutation rates in males more than in females
For the first time, scientists have used large-scale DNA sequencing data to investigate a long-standing evolutionary assumption: DNA mutation rates are influenced by a set of species-specific life-history ...
