See: The Signals Great Apes Use to Communicate

Humans are naturally able to understand many of the signs, or gestures, that wild chimpanzees and bonobos use to communicate with one another, new research finds.

University of St Andrews scientists studying communication in chimpanzees and bonobos tested humans' ability to translate the animals' gestures into a video playback experience.

They say the results suggest the last common ancestor we share with chimpanzees also used signals and gestures. And that these provided an origin for our own language.

Niamh Topping, 23, is in her first year at the University of Leicester studying the reactions of water and rocks in the early solar system.

The Winchcombe meteorite crashed into the Gloucestershire town of Winchcombe in 2021 .

Studies suggest it contains water that almost perfectly matches Earth's.

Ms Topping said: "If we look at something like Winchcombe, we are effectively looking back about 4.6 billion years at the formation of the planets and solar system.

"So that tells us more about how they came about and, in a way, where we came from."
