Understanding the material basis of adaptive evolution has been a central goal in biology dating back to at least the time of Darwin. One focus of current debates is whether adaptive evolution relies ...

A study published in Nature Ecology & Evolution reveals a surprising evolutionary insight: sometimes, losing genes rather than gaining them can help bacterial pathogens survive and thrive. The study ...

A new review argues that conserving medicinal plants under climate change requires protecting adaptive genomic variation, not ...

A new Lancet series says men lose more healthy years than women worldwide and urges governments to address poverty, social pressures, prevention and access to care through men's health policies. The ...
