By NZ Herald. All modern humans descended from a solitary pair who lived 100,000 to 200,000 years ago, scientists say.

Scientists surveyed the genetic “bar codes” of five million animals – including humans – from 100,000 different species and deduced that we sprang from a single pair of adults after a catastrophic event almost wiped out the human race.

These bar codes, or snippets of DNA that reside outside the nuclei of living cells, suggest that it’s not just people who came from a single pair of beings, but nine out of every 10 animal species as well, Daily Mail reports. . .

Stoeckle and Thaler concluded that 90 per cent of all animal species alive today come from parents that all began giving birth at roughly the same time, less than 250,000 years ago – throwing into doubt the patterns of human evolution.

“This conclusion is very surprising and I fought against it as hard as I could, ” Thaler admitted. (Read more from “Scientists Prove All Humans Descended From Two People” HERE)

All Humans Are Descended From Just Two People and a Catastrophic Event Almost Wiped out All Species 100,000 Years Ago, Scientists Claim

By Daily Mail. . .They mined ‘big data’ insights from the world’s fast-growing genetic databases and reviewed a large literature in evolutionary theory, including Darwin.

Dr Stoeckle said: ‘At a time when humans place so much emphasis on individual and group differences, maybe we should spend more time on the ways in which we resemble one another and the rest of the animal kingdom.’

The conclusions throw up considerable mystery as to why the need for human life to start again was needed such a relatively short time ago, especially since the last known extinction we know of was during the time of the dinosaurs 65 million years ago.

This opens up the possibility of an inbuilt human evolutionary process wherein we break down and die out, leaving the need to start from scratch. . .

The ‘mitochondrial DNA’ examined in the research is that which mothers pass down from generation to generation and it showed the ‘absence of human exceptionalism.’ (Read more from “All Humans Are Descended From Just Two People and a Catastrophic Event Almost Wiped out All Species 100,000 Years Ago, Scientists Claim” HERE)

As remarkable as those advances have been, however, they have only occurred on one dimension—the linear sequence of DNA.

Now scientists report in the Proceedings of the National Academy of Sciences their success in manipulating the genome in 3D. The human genome that’s squeezed into every microscopic cell in the body measures more than two meters long. To stuff it into a space just a few microns wide (the human hair, by comparison, is 40 to 50 microns in diameter) requires some masterful origami-like transformation.

In the study, Erez Lieberman Aiden, director of the center for genome architecture at Baylor College of Medicine and Rice University, and his colleagues describe how DNA performs this shrinking act. It turns out that there is a sequence in the genome—a DNA “word”—that signals when a long string of DNA should turn and form a loop. The end of that loop is signaled by the same word but in reverse, a mirror image of the original. Where these matched-up words appear on the genome determines which genes are exposed in a relatively accessible place and therefore which genes are more active. Loops formed in cells in the heart, for example, will be different from ones generated in skin cells or bone cells. (Read more from “Researchers Perform First Surgery on the Human Genome” HERE)
