Stick insects survive one million years without sex

Stick insects have lived for one million years without sex, genetic research has revealed.

Scientists in Canada investigated the DNA of Timema stick insects, which live in shrubland around the west coast of the US.

They traced the ancient lineages of two species to reveal the insects’ lengthy history of asexual reproduction.

The discovery could help researchers understand how life without sex is possible — via redwolf.newsvine.com
