Evolution holds that we all came from a single animal. But what was this animal like?

“This work illustrates that members of complex communities can evolve together, laying the groundwork for future research on how these organisms evolve in response to reliable partnerships.”

Blood is not only teeming with bacterial and viral disease, it is also very poor in nutrients — too few carbs and vitamins, way too much salt.

It’s a miracle Dracula lived as long as he did.

An extraordinary new species of arachnid, resembling a spider with a tail, has been discovered in amber from Myanmar (formerly Burma), of mid-Cretaceous age, around 100 million years ago.

 

“Evolutionary Geneticists Spot Natural Selection Happening Now In People”

Human evolution can seem like a phenomenon of the distant past which applies only to our ancestors living millions of years ago. But human evolution is ongoing. To evolve simply means that mutations – the accidental changes to genes that happen normally in the process of copying DNA – are becoming more or less common in the population over time.

“Evolution delayed during Earth’s middle ages by low oxygen levels: Study”

“It is clear that life has had a profound role in creating the world we are used to, and the planet has similarly affected the trajectory of life. I think it’s important people acknowledge the miracle of their own existence and recognise what an amazing planet this is.”

“World’s oldest fossils found in discovery with ‘staggering’ implications for the search for extra-terrestrial life”

The oldest known fossils – dating back 3.7 billion years to a time when the Earth was still being bombarded by asteroids – have been found in Greenland, scientists announced in a discovery that could have “staggering” implications.

Commenting on the discovery, a Nasa expert on the early Earth said if the fossils were evidence of living creatures then the discovery showed “life is not a fussy, reluctant and unlikely thing” – increasing the chances that it will have developed on Mars and elsewhere in the Universe.

Scientists believe they have an uncovered an evolutionary throwback in a rare deep ocean whale that washed ashore on a South Australian beach.

“Gradual environmental change delays evolution, adaptation”

http://www.upi.com/Science_News/2016/01/07/Gradual-environmental-change-delays-evolution-adaptation/8311452175681/?nll=1

Previous research has suggested rapid or sudden environmental change often precipitate accelerated evolutionary adaptation and speciation. Now, scientists say the opposite is also true.

According to new research out of the Netherlands, slow or subtle environmental change slows evolution, leading to fewer adaptations.

With growing concerns about climate change and the ability of plants and animals to adapt, some scientists have questioned whether slowing down global warming would be beneficial.

“Fish which walks out of water and breathes on land for six days ‘could spell major disaster’ for wildlife in Australia”

A bizarre and seemingly super-powered fish which can walk out of water and breathe on land for up to six days could spell a ‘major disaster’ for wildlife, scientists have warned.

The aggressive climbing perch, which has lungs as well as gills, has been discovered in northern Australia.
