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

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."

IOW, the assumed timeclock in mtDNA mutation rates turned out to be wrong, or to put it another way, mtDNA stability is much greater than previously assumed. Thanks GonzoII.

More approaches have been brought to bear on the emergence and outgrowth of Homo sapiens sapiens (i.e., modern humans) than any other species including full genome sequence analysis of thousands of individuals and tens of thousands of mitochondria, paleontology, anthropology, history and linguistics [61, 142-144]. The congruence of these fields supports the view that modern human mitochondria and Y chromosome originated from conditions that imposed a single sequence on these genetic elements between 100,000 and 200,000 years ago [145-147]. Contemporary sequence data cannot tell whether mitochondrial and Y chromosomes clonality occurred at the same time, i.e., consistent with the extreme bottleneck of a founding pair, or via sorting within a founding population of thousands that was stable for tens of thousands of years [116]. As Kuhn points out unresolvable arguments tend toward rhetoric.Summary and conclusionScience greedily seizes simplicity among complexities. Speciation occurs via alternative pathways distinct in terms of the number of genes involved and the abruptness of transitions [148]. Nuclear variance in modern humans varies by loci in part due to unequal selection [149] and the linkage of neutral sites to those that undergo differential selection. Complexity is the norm when dealing with variance of the nuclear ensemble [150-154]. It is remarkable that despite the diversity of speciation mechanisms and pathways the mitochondrial sequence variance in almost all extant animal species should be constrained within narrow parameters. Mostly synonymous and apparently neutral variation in mitochondria within species shows a similar quantitative pattern across the entire animal kingdom. The pattern is that that most -- over 90% in the best characterized groups -- of the approximately five million barcode sequences cluster into groups with between 0.0% and 0.5% variance as measured by APD, with an average APD of 0.2%. Modern humans are a low-average animal species in terms of the APD. The molecular clock as a heuristic marks 1% sequence divergence per million years which is consistent with evidence for a clonal stage of human mitochondria between 100,000- 200,000 years ago and the 0.1% APD found in the modern human population [34, 155, 156]. A conjunction of factors could bring about the same result. However, one should not as a first impulse seek a complex and multifaceted explanation for one of the clearest, most data rich and general facts in all of evolution. The simple hypothesis is that the same explanation offered for the sequence variation found among modern humans applies equally to the modern populations of essentially all other animal species. 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.Mark Stoeckle and David S Thaler, Why should mitochondria define species?

Just as the Bible states. Uh-oh.

[SunkenCiv]

Just as the Bible says nothing about DNA, mitochondria, or mitachondrial DNA. Uh-oh.

The GPS system represents an enormous long running experiment in relativistic time dilation. At this point the effects are well understood and the GPS system has built in mechanisms to correct clocks automatically.

This as opposed to evolutionary theory, which there is no practical way to test at all.

[pabianice]

Hmmm. Turtles go back 200 million years. Why are they still here?

[metmom]

And that happens naturally in the course of evolution just when?

Man induced genetic changes do nothing to prove evolution.

OTOH, they do go very far in supporting intelligent design.

And besides, what i was asking for was examples of genetic mutations that have ever not been deleterious, that means the ones that happen spontaneously in nature, not the result of planned intentional genetic manipulation.

[Moonman62]

And that happens naturally in the course of evolution just when?

All the time.

Man induced genetic changes do nothing to prove evolution.

I think you should read the article again. Scientists are attempting to replicate natural beneficial mutations for therapeutic purposes.

[metmom]

Give me specific examples of genetic mutations that are not detrimental.

It happens *all the time* is NOT an example.

Every genetic mutation I know of in humans either does nothing, or causes serious birth defects and often results in sterility.

Show me any spontaneous change in genetic mutations that has cause a beneficial change in humans.

bray: "Yes a chimp ancestor.

Your opinion, not science.

bray: "Please give us one fossil piece of evidence of a transitory species."

Every fossil without exception is "transitory" between its ancestors and descendants, if any.

Always delighted to see posts from someone who does this for a living.

srmorton: "...you would be surprised at how many of my students pick it in a multiple choice question as the best summary of the theory of evolution."

Amazing, ever try the Americans with European ancestors analogy?

[bray]

That is the worst lie I have heard about transitory species. Try another excuse why they have not discovered a single transitory fossil.

You atheists will say and do whatever it takes to maintain your fraud.

“Where did the 3 million year old Lucy and other hominids come from?”

I’ve always believed in an old universe, but I suspect there have been multiple creation events.

If you don’t want to read the article I can’t help you.

metmom: "Variation within species is one thing.
Evolution is another entirely."

No, variation within species is exactly the same thing as evolution.
Only the time period examined varies.

Over periods of thousands of years we see new sub-species.
Over, say, a hundred thousand years we see new species.
Over a million years we see new genera, etc., etc.
Always the processes are the same, only the period of accumulated changes changes.

metmom: "Taking observed variation within species and extrapolating evolution out of it is presumptuous at best and not supported by actual evidence."

What's presumptuous is ignoring clear evidence from fossils, morphological studies and DNA that variation within species over time becomes evolution of new species.

metmom: "Show me any evidence anywhere that a change in the normal number of chromosomes in a human being has ever had either a positive or neutral effect instead of being deleterious."

Nobody pretends that science has all the answers now, or ever will, but one clear advantage for us to the fusion of chromosomes in our ancient ancestors was it absolutely prevented any further cross-breeding between them and other great-apes.

I suspect that Metmom meant “Variation within a ‘kind.’”

That is the term used biblically.

“Species” is an imaginary human construct that may have no validity whatsoever in Yehova’s realm.

Man lacks the authority to make the rules.

[BroJoeK]

bray: "That is the worst lie I have heard about transitory species"

Sorry if you hate the truth, but it's still true.

bray: "Try another excuse why they have not discovered a single transitory fossil."

But they have found, since every fossil without exception is transitory between its ancestors and descendants, if any.
Of course, you are free to close your eyes and pretend not to see, but truth remains true regardless.

bray: "You atheists will say and do whatever it takes to maintain your fraud."

No, only the truth.

[editor-surveyor]

The “evidence from fossils” so completely demolished “evolution” that Darwin disavowed it himself.

[BroJoeK]

editor-surveyor: "I suspect that Metmom meant “Variation within a ‘kind.’”
That is the term used biblically."

I got that, but "kind" has no known scientific equivalent.

editor-surveyor: " 'Species' is an imaginary human construct that may have no validity whatsoever in Yehova’s realm."

Just as other biological classifications: genus, family, order, etc.
All just scientific constructs which make it a bit easier for us to understand the natural realm.

editor-surveyor: "Man lacks the authority to make the rules."

The Bible gives us authority to name things, and that's what biological classifications are, names for categories.
I'm not troubled by it.

“Scientific” is a term that defies reason when used to describe the arbitrary constructs of arbitrary ‘biology.’
