Big News About Early Humans in the New World

There has been a lot of news recently about our ancestors – where they evolved and settled, and when – and these discoveries seem to imply that we are the verge of a new and exciting understanding about our origins…

 

In British Columbia, scientists have discovered a village site that is estimated to be three times as old as the Great Pyramid at Giza and among the most ancient human settlements in North America.

But even more intense is the newly found evidence that Neanderthals — or another lost species — occupied what is now California some 130,000 years ago!

Humans Lived in North America 130,000 Years Ago, Study Claims

by Carl Zimmer (4/26/17)

 

 

“Prehistoric humans — perhaps Neanderthals or another lost species — occupied what is now California some 130,000 years ago, a team of scientists reported on Wednesday.

 

The bold and fiercely disputed claim, published in the journal Nature, is based on a study of mastodon bones discovered near San Diego. If the scientists are right, they would significantly alter our understanding of how humans spread around the planet.

 

The earliest widely accepted evidence of people in the Americas is less than 15,000 years old. Genetic studies strongly support the idea that those people were the ancestors of living Native Americans, arriving in North America from Asia.

 

If humans actually were in North America over 100,000 years earlier, they may not be related to any living group of people. Modern humans probably did not expand out of Africa until 50,000 to 80,000 years ago, recent genetic studies have shown…”

Climate change is melting permafrost soils, releasing ancient viruses and bacteria

There are diseases hidden in ice, and they are waking up

By Jasmin Fox-Skelly

 

Long-dormant bacteria and viruses, trapped in ice and permafrost for centuries, are reviving as Earth’s climate warms

 

“Throughout history, humans have existed side-by-side with bacteria and viruses. From the bubonic plague to smallpox, we have evolved to resist them, and in response they have developed new ways of infecting us.

 

We have had antibiotics for almost a century, ever since Alexander Fleming discovered penicillin. In response, bacteria have responded by evolving antibiotic resistance. The battle is endless: because we spend so much time with pathogens, we sometimes develop a kind of natural stalemate.

 

However, what would happen if we were suddenly exposed to deadly bacteria and viruses that have been absent for thousands of years, or that we have never met before?

 

We may be about to find out. Climate change is melting permafrost soils that have been frozen for thousands of years, and as the soils melt they are releasing ancient viruses and bacteria that, having lain dormant, are springing back to life…”

Mysterious post-mortem delta waves found in the brain…

Is there life after death for our brains? The evidence says it depends.

Brain Activity At The Moment of Death
By Neuroskeptic

What happens in the brain when we die?

 

Canadian researchers Loretta Norton and colleagues of the University of Western Ontario examine this grave question in a new paper: Electroencephalographic Recordings During Withdrawal of Life-Sustaining Therapy Until 30 Minutes After Declaration of Death.

Norton et al. examined frontal EEG recordings from four critically ill patients at the point where their life support was withdrawn.

 

What they found were post-mortem delta waves that the authors say are very hard to explain:

 

It is difficult to posit a physiological basis for this EEG activity given that it occurs after a prolonged loss of circulation. These waveform bursts could, therefore, be artefactual in nature, although an artefactual source could not be identified.

Another interesting finding was that the actual moment at which the heart stopped was not associated with any abrupt change in the EEG. The authors found no evidence of the large “delta blip” (the so-called “death wave“), an electrical phenomena which has been observed in rats following decapitation.
