Lemurs first arrived on the island of Madagascar 53.2 million years ago, probably hitching a ride on a vegetation raft from mainland Africa. The island was predator free, and the lemurs evolved into ...

Humans can genetically modify plants and animals to be more resilient to climate change and disease. But the scientific community is divided about whether the tool should be put to use in nature.

When species interact with each other, they do not evolve separately, but do so together. This process is called coevolution. Natural selection favors predators that are better at capturing prey, and ...
