‘Risk of a mass extinction’ is rising

By now you’ve probably heard the headlines about the extinction of the dinosaurs and the potential for an ecological and human-induced catastrophe.

But, for those of us who are not aware of the threat, the threat of a global ecological crisis looms large.

It’s a real, existential threat that threatens to threaten the existence of the species we call Homo sapiens.

It is a threat that could be the difference between life and death.

The key problem is that the threat is so complex and multifaceted that it can’t be fully understood in the short-term or even the medium term.

And yet, the science and the predictions are clear.

It has been known for some time that there is a potential for the extinction and/or extinction of Homo sapien species, even if we never actually reach that point.

But it’s important to understand that it is not just the extinction, but the emergence of a new species that is the real risk, according to new research published in the Proceedings of the National Academy of Sciences.

It is not only the potential extinction of a large part of our species that could make it so difficult to survive.

What’s more, there is evidence that the current extinction could become the first such event in human history, according the authors of the paper.

The researchers at the University of Bristol, led by professor Michael Pouw, have done extensive research on the evolution of the human lineage.

Their results, published in PLOS Biology, show that, over the past 200,000 years, the human species has undergone a dramatic shift in its genetic composition.

The human lineage has undergone four major stages, or phyla, and, as we have learned, humans are descended from a single group of ancestors who split from the group that is currently known as the Australopithecus, which is believed to be the oldest of the apes.

In the new study, Pouwin and his colleagues looked at the DNA of around 5,000 human fossils from the last 40,000 to the present.

The scientists found that, as the humans evolved, there was an evolutionary bottleneck, and they found that a single gene from the human gene coding for the enzyme called the “protease kinase 2B” had disappeared.

“In other words, the gene that we all know as the human protein is gone, and the rest of the genome has evolved, with an extra gene to help it,” said Pouwit.

“This gene, which we call the ‘proteasome’ gene, was important in the development of our skin and our eyes, as well as other adaptations we use for movement and social interaction.

It helped our ancestors move about, foraging for food, and even foraging in caves.

And the new discovery suggests that the loss of this gene was a crucial step in this evolution.

The new gene was important because it made it possible for the body to produce new proteins that were needed to build the skin of our body, our eyes and the skin and the bones of our bones.

The researchers speculate that this process of the body building proteins from old DNA, in turn, resulted in the emergence and spread of our complex human genome.

In a nutshell, the researchers found that when the human genome was first sequenced, the protease gene went extinct about 20,000 or so years ago.

In fact, it disappeared entirely by about 200,00 years ago, a time when we were at the beginning of the third mass extinction event known as Cretaceous mass extinction.

Pouw said that the researchers also found evidence that, in some cases, the evolution or mutation of the new genes might be linked to the loss or disappearance of the old ones.”

For example, if you have a gene that is highly mutated in the human population and it’s very common to see mutations in the gene, it could be that the mutation was the result of the population that went extinct, or if it was the mutation of a different gene,” he said.”

We see this in the fact that mutations have been observed in genes that were important in different parts of the evolutionary tree of life, and this is a new finding in our study.

“The researchers also looked at how the evolution happened, using DNA sequences from the genomes of various species and examining the relationships between the genes that are known to be important for different parts or functions of the genes.”

It’s really quite fascinating that in this study, we see that a major component of the DNA sequence is related to the gene of the proton pump, which was also a major factor in the evolution in humans,” said lead author Michael B. Stearns, also from the University.”

The new results provide some interesting insights into the evolution and evolution of our genomes and how this happened,” said co-author and Ph.

D. candidate James D. Sibley, from the Department of Earth and Planetary Sciences at the California Institute of Technology.”

One of the things we find fascinating is that we
