Why do males and females so often age and die at different rates?
We argue that sex-specific mutation accumulation may be the most parsimonious evolutionary explanation for sex-biased ageing:

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/...
