The evolution of sex remains one of biology's greatest puzzles. While sexual reproduction dominates across the animal kingdom ...

Drosophila is one of the most thoroughly studied lab animals -- with the exception of the female reproductive tract. Now a team of biologists has taken the first deep look at the Drosophila uterus and ...

The phenomenon of aphids born pregnant is one of nature’s most unusual reproductive strategies. In these tiny insects, reproduction happens at such a fast pace that newborn aphids may already carry ...
