https://www.smithsonianmag.com/science- ... 180959593/In reality, a mitochondrial Eve is not the first female of a species, but merely the most recent female historically from which all living animals of a species can trace their ancestry. Think of her like the peak of a genealogical pyramid, in which all ancestors of a species meet. While everyone below is descended from her, that doesn’t mean that there is no other female above her, or that lived at the same time as her.
No..... the author is playing with semantics.
I love exercising critical thinking skills.. (always go a little farther in your research , just don't pull the first thing that you agree with ... its called Confirmation Bias)
Joshua Rapp Learn, the author bounces around and pulls a lot of quotes from different people to put a spin on it. In fact he misquote Marak Kimmel... his published study actually points to a Homo Sapien mitochondrial Eve. ( the exact opposite of what Joshua Rapp Learn is trying to say with conjecture)
Take a second to read out loud that quote from your article above, with particular attention to the "bold" text. IF the
subject is historically "the animal" that all species can trace their ancestry from, & where all ancestors meet (as modern science has proved with homo sapiens ) the subject is indeed the Mitochondrial Eve. The author (Joshua Rapp Learn) is using conjecture (in the part I underlined after the bold ) without offering up any proof that Eve was not the first female ...
that is the actual hypothetical part. It is very important we remember that science has not found the a missing link. (where two species share the same geno) The author (Joshua Rapp Learn ) assumes there is one (and.... there might be... we don't know.) However, what we do know... is in the last 100yrs, 33 times science have stated they have found missing link, only to retract it, and the bones from all 33 discoveries combined, fit in a box in an average living room. (in all cases are to small of a sampling to be creditable.)
The author (Joshua Rapp Learn) uses Marek Kimmel a professor of statistical genetics and molecular evolution at Rice University. (Joshua Rapp Learn) quotes Kimmel
"Genes from a species will be eliminated.” Citing there must have been a female before the Homo Sapien Mitochondrial Eve. (WE DON"T KNOW THAT FOR NONE HAVE BEEM FOUND) I assume the quote is talking about Neanderthals.
? We know they existed, sure. But they died out... in it's place Homo sapiens (the only extant Hominina species on the planet) and once again
all of us have that Mitochondrial Eve gene. No one has been found without that Mitochondrial Eve gene.
Marak Kimmel published a study in 2010 that places the mitochondrial Eve of humans back to around 100,000 to 250,000 years ago (a 2013 study estimated the age as a little more recent)
https://www.sciencedaily.com/releases/2 ... 122405.htm Summary: of his study
The most robust statistical examination to date of our species' genetic links to "mitochondrial Eve" -- the maternal ancestor of all living humans --
confirms that she lived about 200,000 years ago. The study was based on a side-by-side comparison of 10 human genetic models that each aim to determine when Eve lived using a very different set of assumptions about the way humans migrated, expanded and spread across Earth.
