Caveman poo suggests they may have eaten vegetables

Scientists studying Neanderthal poo say that our prehistoric ancestors ate far more vegetables than had been thought.


Who were the Neanderthals?

  • Their ancestors left Africa 400,000 years ago
  • They travelled to Europe and Asia where they evolved into Neanderthals
  • They went extinct 30,000 years ago

Researchers examined ancient specimens of poo, from people who lived in part of southern Spain 50,000 years ago.
They found that while all the samples contained traces of meat, but two showed signs of plant matter, suggesting they ate their veg too.
The study's authors say the results will help us understand how humans have come to dominate the planet.
By doing detailed tests on the ancient poo, the team found that while meat was the main part of Neanderthals' diet, they may have also consumed a fairly regular portion of plants, such as tubers, berries, and nuts.
"We believe Neanderthals probably ate what was available in different situations, seasons, and climates," says Ainara Sistiaga, from the University of La Laguna in Spain, who worked on the study with colleagues from MIT in America.
Traces in the teeth
This latest finding comes after the recent discovery of plant microfossils trapped in Neanderthal teeth - which some thought might suggest fruit and veg in their diet.
But Ainara's more cautious about the teeth evidence: "Sometimes in prehistoric societies, they used their teeth as tools, biting plants, among other things.

"We can't assume they were actually eating the plants based on finding microfossils in their teeth."
The traces this study found in the poo, suggest the first direct evidence for a more varied diet for our cavemen ancestors.


The results of the study were published in the journal PLoS One.

Google Glass goes on sale in UK

Google have released their wearable technology device, Glass, in the UK.


The device, which is still a prototype at the moment, costs £1,000 and you have to be over 18 to buy it.
Glass lets you film stuff and check the internet on the move, with a built-in camera and microphone to record photos, video and sounds.
Google says Glass is a hands-free, quick alternative to smartphones - but some people are concerned about privacy and that using Glass while driving would be unsafe.

Being allowed to play computer games in school lessons - sounds too good to be true.

Being allowed to play computer games in school lessons - sounds too good to be true!

Pupil playing Minecraft


But more than 200 UK schools are using a specially adapted version of the popular game Minecraft to help pupils to learn.
Minecraft is set in a virtual world where players build with blocks of different materials.
At one school, children play the game and then write stories inspired by their experience.
Teachers using the game say it can help get kids who don't like books to do more reading and writing.

Computer games have been blamed in the past for causing violence and addiction, but now some schools are encouraging children to play them in lessons to help with more traditional subjects.
So could "Angry Birds" help with trigonometry, or "The Sims" with social science?
Tim Muffett has been to a school in Barnsley which is using Minecraft in its English lessons.
