Fossils

Analyzing fossils can be difficult -- especially when they're so small that they can only be seen with a microscope. Researchers have now come up with a solution.

In most vertebrates, a pattern of chemical marks on the genome is a reliable indicator of age, but in axolotls this clock seems to stop after the first four years of life

An octopus will work with several different species of fish to find and catch prey - and punch those that aren't helping

A new, wide-ranging exploration of human remains casts doubt on a long-standing theory in archaeology known as the Kurgan hypothesis -- which, among other claims, suggests that humans first domesticated horses as early as the fourth millennium B.C.

A new study offers the most detailed glimpse yet into how Earth's surface temperature has changed over the past 485 million years. The data show that Earth has been and can be warmer than today -- but humans and animals cannot adapt fast enough to keep up with human-caused climate change.

Ancient DNA has provided spectacular insights into human history, particularly in Europe and Asia, where researchers have reconstructed the genomes of thousands of people. However, fewer than two dozen ancient genomes have been recovered from southern Africa -- specifically Botswana, South Africa and Zambia -- which has some of the world's earliest evidence of modern humans, with the oldest genomes dating back around 2,000 years.

African giant pouched rats proved adept at detecting four commonly trafficked products derived from endangered species including rhino horn and elephant ivory

We are finally untangling the ancient history of the cactus family, revealing some surprising forces that shaped these plants – ­­­­­­and prompting concern for their future

A researcher has found evidence that the treeless, rugged, grassland landscape of the Falkland Islands was home to a lush, diverse rainforest up to 30 million years ago.

Some of the most dramatic climatic events in our planet's history are 'Snowball Earth' events that happened hundreds of millions of years ago, when almost the entire planet was encased in ice up to 0.6 miles thick. New research provides a more complete picture for how the last Snowball Earth event ended, and suggests why it preceded a dramatic expansion of life on Earth, including the emergence of the first animals.

A mysterious tusked animal depicted in South African rock art might portray an ancient species preserved as fossils in the same region, according to a new study.

Some lizards dive into streams to escape predators, and a specialised bubble-breathing technique enables them to stay submerged for up to 18 minutes

Echolocating bats can more easily find and pollinate long-stemmed flowers that stand out from the surrounding foliage, which may be why this floral trait evolved

New research examines thousands of years of Arctic sled dog ancestry and reveals when and how Siberian and Alaskan sled dogs' DNA mixed.

A species of leaf chameleon newly named Brookesia nofy was discovered in a patch of coastal rainforest, a highly threatened habitat in Madagascar
