Nearly 2 decades ago, DNA inside a pinkie finger bone found in a Siberian cave revealed the existence of what are now known as the Denisovans, an extinct close evolutionary cousin of Neanderthals and our own species.

But in the years since, only a skull and a few more teeth and bone fragments have been definitively linked to these mysterious humans, making it difficult to determine what the rest of their bodies looked like.

Now, researchers report that a pair of ancient leg bones, a femur and partial tibia, scooped up from the bottom of the Strait of Taiwan, may hold valuable clues.

Koalas face numerous challenges, but chlamydia is one of the gravest. In many populations, around 50 percent of the marsupials are infected, leading to issues such as infertility, blindness, and starvation. As the disease spreads through wild populations, Australia has approved a vaccine that could become an important new tool for protecting the vulnerable species.

An analysis of fossil mammals suggests that Mexico served as a long-term evolutionary “holding pen” where North American species adapted and diversified for millions of years before sweeping into South America 2.8 million years ago.

The findings in Science clarify the timing of one of Earth's most consequential migrations and may help explain why North American mammals were more successful migrants than those from South America.

A new analysis in Science of more than 116,000 bird songs has revealed that the astonishing variety of passerine birdsong is built from just eight basic acoustic motifs, like trills, whistles, and harmonic notes.

The findings also reveal that local environments greatly shape how birds communicate around the world.
