The propagation of admixture-derived evolutionary potential

Adaptive radiation—the rapid evolution of many new species from a single ancestor—is a major focus in evolutionary biology. Adaptive radiations often show remarkable repeatability where lineages have undergone multiple ...

New study rebuts 75-year-old belief in reptile evolution

Challenging a 75-year-old notion about how and when reptiles evolved during the past 300 million-plus years involves a lot of camerawork, loads of CT scanning, and, most of all, thousands of miles of travel. Just check the ...

Did adaptive radiations shape reptile evolution?

Some of the most fundamental questions in evolution remain unanswered, such as when and how extremely diverse groups of animals—for example reptiles—first evolved. For seventy-five years, adaptive radiations—the relatively ...

Larger than life: Augmented ants

An ant the size of a lion isn't as far-fetched as you would think. From as small as a sesame seed to the size of a big cat, ants come in all sizes—in augmented reality, at least.

Hybridization boosts evolution

Animals that have either migrated to or been introduced in Central Europe, such as the Asian bush mosquito or the Asian ladybeetle, have adapted well to their new homes due to changing climatic conditions. If these newcomers ...

'First arrival' hypothesis in Darwin's finches gets some caveats

Being first in a new ecosystem provides major advantages for pioneering species, but the benefits may depend on just how competitive later-arriving species are. That is among the conclusions in a new study testing the importance ...
