Phys.org / Social mammals live longer—but bigger groups don't add that many extra years

A new study, published in Ecology and Evolution, shows that social living is associated with longer lifespan, but also that the benefits of sociality level off once animals move beyond living in pairs.

Phys.org / Asexual lizards, virgin births and clones—the all‑female species of the animal kingdom

It may sound too bizarre to be true, but the Amazon molly (Poecilia formosa), a fish that inhabits rivers, lakes, and swamps in Mexico and Texas, exists over much of its range in populations that are 100% female. In 1932, ...
