Experts insist there is no scientific reason for allowing these fossils to travel to space.
Research shows that sleep deprivation impairs communication between brain regions and brain blood flow, damages brain wiring and makes a young brain look like an aged brain.

Ancient humans chose to sleep less, which had evolutionary benefits. For modern humans, sleeping less is futile and detrimental, but fitness may be a powerful ally in today’s epidemic of sleep loss.
There are areas of biology that may be considered optional at younger year levels, such as botany, entomology and marine ecosystems. Evolution is not one of these.

Scientists had figured a fossil found in Spain more than a century ago was from a Neandertal. But a new analysis suggests it could be from a lost lineage of our species, Homo sapiens.
An ape that lived 21 million years ago was used to a habitat that was both grassy and wooded.

Contrary to the idea that apes evolved their upright posture to reach for fruit in the forest canopy, the earliest known ape with this stature, Morotopithecus, lived in more open grassy environments.
The findings suggest we weren’t the first advanced carnivore among the hominins, as has been previously assumed.
Any hominid fossil find with molar teeth can be plugged into a new equation that reveals its species’ prenatal growth rate.

Using a new equation based on today’s primates, scientists can take a few molar teeth from an extinct fossil species and reconstruct exactly how fast their offspring grew during gestation.
The evolutionary loss of body hair made it easier for human ancestors to hunt in the heat.

The human Y chromosome could disappear over time, putting our species in jeopardy. But some rodents have managed just fine without it – and we now know how.
Ajnabia odysseus lived 66 million years ago, making it one of the last dinosaurs on Earth.

New genetic research shows humans’ famed ability to adapt our behaviour and develop new tools and techniques has not always been enough to survive when times have grown tough.
