DNA from soil could soon reveal who lived in ice age caves
The recovery of ancient DNA is no longer limited to bones.

Why ice sheets will keep melting for centuries to come
Ice sheets respond slowly to changes in climate, because they are so massive that they themselves dominate the climate conditions over and around them. But once they start flowing faster towards the shore…
Brazil’s Atlantic Forest will change more in the next 50 years than at any time since the last ice age
For one of Earth’s most biodiverse forests, 21,000 years of natural change pale in comparison to modern, man-made climate breakdown.
Rising methane could be a sign that Earth’s climate is part‑way through a ‘termination‑level transition’
The last time methane in the air rose so fast, Greenland warmed by 10°C within decades.
First Americans lived on land bridge for thousands of years, genetics study suggests
The theory that the Americas were populated by humans crossing from Siberia to Alaska across a land bridge was first proposed as far back as 1590, and has been generally accepted since the 1930s. But genetic…
Fossil footprints prove humans populated the Americas thousands of years earlier than we thought
The New Mexico findings could rewrite the history of human migration to the Americas.
Fossil footprints: the fascinating story behind the longest known prehistoric journey
Some 13,000 years ago, an adult carrying in a child walked 1.5km in mud at great speed in the presence of hungry predators.
How mapping the weather 12,000 years ago can help predict future climate change
Ice Age glaciers can help us track the jet stream 12,000 ago, and by comparing its path today we can see how it’s moving northwards, changing weather patterns and indicating climate change.
Ancient DNA in lake mud sheds light on the mystery of how humans first reached America
A new study suggests the first humans probably got to America from Siberia via the Pacific coast rather than through a corridor between two giant ice sheets, as previously thought.
How we discovered that an asteroid collision in space 466m years ago boosted life on Earth
Dust from the breakup of an asteroid changed the Earth’s climate and led to an increase in marine biodiversity, study shows.
