Relationship patterns among flightless stick insects suggest that birds disperse the eggs after eating gravid females. Lab experiments previously suggested the possibility, but a new genetic analysis ... Stick insects that reproduce asexually cannot adapt as quickly in the course of evolution as sexually reproducing species, leading to a decrease in biological diversity, according to new ...
Stick and leaf insects are a strikingly bizarre group of insects with a worldwide distribution. They are famous for their impressively large body size and their remarkable ability to camouflage ...

On repeat: Biologists observe recurring evolutionary changes, over time, in stick insectsA long-standing debate among evolutionary scientists goes something like this: Does evolution happen in a predictable pattern or does it depend on chance events and contingency? That is, if you could turn back the clock, as celebrated scientist Stephen Jay Gould (1941–2002) described in his famous metaphor, 'Replaying the Tape of Life,' would life...

Biologists study trade-offs of microscopic predatorsThe drama of predators vs. prey—hunting, stalking, fleeing—isn't limited to the animal kingdom. Underneath our feet, hungry amoebae in the soil pursue and eat bacteria in a microscopic wild kingdom. But being a predator has its own costs, and that's as true for amoebae as it is for lions or wolves.

Geologists, biologists unearth the atomic fingerprints of cancerEarth scientists have long turned to minute differences in hydrogen atoms to explore the ancient history of our planet. A new study suggests that these same tiny atoms might also lead to new ways to track the growth of cancer.
