Massive Genetic Study Reveals 90 Percent Of Earth’s Animals Appeared At The Same Time

Massive Genetic Study Reveals 90 Percent Of Earth’s Animals Appeared At The Same Time

30 May 2018, 7:01 am EDT By Nicole Arce Tech Times

Landmark new research that involves analyzing millions of DNA barcodes has debunked much about what we know today about the evolution of species.

In a massive genetic study, senior research associate at the Program for the Human Environment at Rockefeller University Mark Stoeckle and University of Basel geneticist David Thaler discovered that virtually 90 percent of all animals on Earth appeared at right around the same time.

More specifically, they found out that 9 out of 10 animal species on the planet came to being at the same time as humans did some 100,000 to 200,000 years ago.

"This conclusion is very surprising," says Thaler, "and I fought against it as hard as I could."

What Is DNA Barcoding?
Over the last decade, hundreds of scientists collected around 5 million DNA barcodes from 100,000 animal species in different parts of the globe. Stoeckle and Thaler looked through these 5 million genetic imprints to find one of the most surprising discoveries about evolution to date.

There are two types of DNA. Most people know nuclear DNA. This is the DNA containing the genetic blueprint for each single individual. It is passed down from the parents to the offspring. The genome is made from kinds types of molecules arranged in pairs. There are 3 billion of these pairs, which are then used to form thousands of genes.

The other, less familiar type of DNA is one found in the mitochondria of cells. The mitochondria generate energy for the cell and contains 37 genes. One of these is the COI gene, which is used to create DNA barcodes. All species have a very similar mitochondrial DNA, but their DNA is also different enough so we can distinguish between species.

Paul Hebert, biologist and director of the Biodiversity Institute of Ontario, developed a new way to identify species by studying the COI gene.

Born Around The Same Time
In analyzing the COI of 100,000 species, Stoeckle and Thaler arrived at the conclusion that most animals appeared simultaneously. They found that the neutral mutation across species were not as varied as expected. Neutral mutation refers to the slight DNA changes that occur across generations. They can be compared to tree rings because they can tell how old a certain specie or individual is.

As to how that could have happened, it's unclear. A likely possibility is the occurrence of a sudden event that caused large-scale environmental trauma and wiped out majority of the Earth's species.

"Viruses, ice ages, successful new competitors, loss of prey — all these may cause periods when the population of an animal drops sharply," explains Jesse Ausubel, director of the Program for the Human Environment.

Such times give rise to sweeping genetic changes across the planet, causing new species to appear. However, the last time such an occurrence took place was 65 million years ago, when an asteroid hit the Earth and killed off the dinosaurs and half of all other species on the planet.

The study is published in the journal Human Evolution:

I kept saying 100,000 years ago but the story says between 200,000 and 100,000.

Did you read the actual source material? It says in the opening about 100k years ago.

From the OP it says 100,000 to 200,000(bolded part above). That would mean the event would have happened prior to that.

Edit: That might have come from the study here
"Namely that
the extant population, no matter what its current size or similarity to fossils of any age,
has expanded from mitochondrial uniformity within the past 200,000 years."

I'll read this later, but I'm 100% certain the OP is misrepresenting the actual findings.

This is why I hate pop science.

I don't feel like explaining bottle necks, extinction events, and how 99% of animal species in earth history are already extinct.

Google 'punctuated equilibrium'.

Also, look up how mitochondrial DNA is passed down.

It's passed down from mothers. All humans share a mitochondrial ancestor.

In other words... all humans on earth are descended from a single female. She's known as mitochondrial Eve... and she's probably not even human.

It's sensible other species would have something similar going on if there was a mass extinction... which there was around that time.

This is very interesting, but it fits within the framework of the mechanisms we know of.

You might already know this but I suggest others check it out as well, did you know they have actually made human babies from three sets of DNA? Very cool science really.

If a mother has some sort of disease that arises from her mitochondrial DNA it will always be passed on to offspring as the mitochondrial DNA always comes from the mother. So some really smart guys figured out how to suck the mitochondrial DNA out of the egg and replacing it with another donors DNA. The egg can then be fertilized and allowed to multiply. It has been done and there are walking talking humans on the planet that have come from three sets of DNA.

And here’s your plausible explanation. Toba catastrophe 75k years ago. Cheetahs went through a population bottleneck that they still haven’t recovered from. Humans were down to as few as 3-10k people.

But it’s biblical creation y’all

damn, didn’t even have to dust off the ol’ Genetics PhD to kill it.
This means that everything we know is wrong. Evolution, Creationistism, Pastafarianism, Rubberbandism, String Theorism, and Big Bangianism as well. The earth isn't 6000 years old. My world is now not only upside down, but inside out, and backwards too

This does not mean there was one a single female alive, which is a common math confusion.

Say, 100 generations ago there were 100 females and 100 males. Paired up they have 2 kids each, on average. The same continues for 100 generations. In the first generation, the population can trace itself back to 100 females. But of those 100 mothers who each have 2 children, 25ish will have two daughters, 50ish will have 1 of each, and 25ish will have two sons. These last 25 mothers will no longer be represented in subsequent generations in a female to female inheritance.

If those 100 founder females each had a distinct mitochondrial "barcode" that means that 25 of those distinct mitochondrial barcodes would have been lost in the first generation.

In the next generation on average 17 more of the founding 100 barcodes are lost. The rate of loss slows down but continues. Even though the population size stays the same, more of the original maternal lines go extinct.

That's the basic math for those interested.

I believe they also offer that as an explanation for the Grand Canyon. Of course, they don't realize that the time it took to carve out the Grand Canyon is relatively minimal. What took millions of years was laying down the layers of sedimentary rock in the first place.

Depends.

Humans, apes, and modern monkeys all evolved from what we call 'old world monkeys'. All of these species are now extinct.

We didn't evolve from new world /modern monkeys. We just share an ancestor.

Right. I hope my truncated blurb didn't give that impression. I'm glad you detailed the explanation, because I'm just not in the mood to explain the inheritance of mitochondrial DNA. I'm not sure I understand it will enough to explain it properly anyway. I understand it internally, but fail to explain it frequently.

Jesus Christ Lone, did we find some common ground here? I'm curious how much you know about this now.
