1/ A new article in
@Ecology_Letters by a group of evolutionary biologists—pioneers and leading experts on the evolution of sex. (The article is open access, short, and clear.)
"Biological sex is best defined as a binary classification of male and female reproductive strategies rooted in anisogamy, characterised by the production of two discrete gamete types of different sizes."
"We call for a more differentiated discourse on sex, one that separates the scientific conception of biological sex from societal discussions regarding the diversity of gender expressions and identities in humans."
