Several studies have upended what we thought we knew about mummification using scientific dating techniques to reveal some fascinating – and surprising – insights.
Human remains dating back more than 30,000 years were found at Paviland cave in Gower.

A more precise timeline now shows Polynesian ancestors of Māori first settled in the North Island before expanding south and then retreating again when the climate changed.
Did people settle these islands by traveling north from South America, or in the other direction? Reanalyzing data from artifacts discovered decades ago provides a definitive answer.
The updated methods are providing a clearer picture of how Earth and its inhabitants evolved over the past 60,000 years - and thus, providing new insight into its future.
Modern dating techniques are providing new time frames for indigenous settlements in Northeast North America, free from the Eurocentric bias that previously led to incorrect assumptions.
Old-growth forests prevailed in New England for thousands of years.

Evidence shows Native Americans in New England lived lightly on the land for thousands of years. It wasn’t until Europeans arrived that the landscape experienced major human impacts.
Lake Taupo, in the North Island of New Zealand, is a globally significant caldera of a supervolcano that formed following a massive eruption more than 20,000 years ago.

New research shows that carbon dioxide in groundwater can affect the aging of volcanic eruptions. The findings could help predict future eruptions.
In July 2017, new research was published that pushed the opening chapters of Australian history back to 65,000 years ago.

Today's episode of Essays On Air, the audio version of our Friday essay series, seeks to move beyond the view of ancient Australia as a timeless and traditional foundation story.
It turns out that the world is about 4,600,000,000 years old. That’s 4.6 billion years. That’s pretty old!

The world is made of tiny building blocks called ‘elements’. Scientists have worked out how fast some elements change into other elements. That gives us a very big clue about how old the Earth is.
Our cells have a built-in genetic clock, tracking time… but how accurately?

How do scientists figure out when evolutionary events – like species splitting away from a common ancestor – happened? It turns out our DNA is a kind of molecular clock, keeping time via genetic changes.

The identification of fakes and forgeries is a basic issue that has always raised controversy. This is unsurprising, of course – the enormous sums garnered by top paintings would turn to dust as soon as…
