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."
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.
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 always loved the question: If humans evolved from monkees, how come there are still monkees?”
I don’t know why you love it. According to evolutionary theory, monkeys, apes and humans evolved from a distant ancestor. Humans did not evolve from monkeys.
Two “i”s, but I didn’t feel like fighting with auto correct.
15,000 species of birds and mammals, alone, and food for a year. Did the koalas bring therir own eucalyptus leaves?

Freudian slip. Was thinking a lot about pie...
Hmmm, now can that happen? Maybe we should ask a sneering sanctimonious Hollyweird starlet leftist. They’re very scientific, donchakno. Cher! We’ll ask Cher.
Depends how you count.

Tallying the Passengers
Using the family criterion in combination with the “breath of life” criterion, the total number of kinds on board the Ark was low. Today, the number of living mammal, amphibian, reptile, and bird families (including the aquatic ones) is just over 500.6
If we include fossils, the number increases. In relative terms, the increase is significant, but in terms of absolute numbers, the new total represents a small fraction of the diversity of life on the planet. Among mammals, amphibians, reptiles, and birds, the mammals have the most diverse fossil record. Only about 30% of all mammal families that ever existed are alive today.7 Assuming a similar percentage for amphibians, reptiles, and birds, we can estimate how many total families in these groups of creatures ever existed.
If 510 families exist in these groups today, and if this represents just 30% of all that ever lived, then a total of 1,700 mammalian, amphibian, reptilian, and avian families8 once existed on earth. This number—1,700—represents an upper estimate of the total number of kinds that Noah took on board the Ark
So, he took representatives of Families, and the rest of extant species evolved from them? Search shows “platypodes” is the correct Greek plural. and autocorrect wants it to be “platypuses. “
Even Swiss Cheese has fewer holes than this piece

I, for one, and know I speak for many ... am eager for you to educate us. I can tell how smart you are ! That swiss cheese thing and all. That cracked me up. Sorta brought it all home, to see the foolish error of my ways.
So how did evolution happen all at once. Doesn’t the atheistic theory say it takes billions and billions of years? This shows just the opposite.
For evolutionists everything proves evolution just like everything proves Global Warming.
Well, there are three monkees left - Peter, Michael, and Mickey. Davy passes away in 2012. I’m a Believer!
“...everything proves evolution just like everything proves Global Warming.”
I was a skeptic too.
Then I witnessed a common wrong-headed jackass species called Global Warming evolve into a multi-headed unicorn species called Climate Change. And, somehow, within less than one generation.
Now I believe.
Read my post #37. It didn’t happen all at once.
“So, he took representatives of Families, and the rest of extant species evolved from them?”
The correct answer is that it is not recorded beyond “kind.”
My theory is that each kind contained the entire range of DNA, that allowed the kind to adjust to be a best fit version for its environment and food supply.
Just a theory, but it fits the observable evidence and patterns of creation.
“Search shows “platypodes” is the correct Greek plural. and autocorrect wants it to be “platypuses. “
Thanks. Good to know, but platypii sounds better.
Ha, you’re the only one who caught that! The second I hit the “post” button I realized the error. Long weekend.
Looks like science just proved the theory false.
“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.”
So T-Rex lived 125,000 years ago?

No. What’s false is the article which is Fake News. It’s been posted multiple times since June and it’s garbage.
