"A 4,500-year-old Y chromosome molecular clock

Our results demonstrate that a Y chromosome molecular clock exists, and that it specifies about 4,500 years in total for human paternal history (figs. 1, 3). Rather than being an anomaly, these results fall in line with the expectations derived from comparisons of low coverage and high coverage Y chromosome sequences (Poznik et al. 2016). Since high coverage sequencing is known to increase the tree tip length over the lengths derived from low coverage sequencing, and since father-son relationships among the living represent the most terminal aspect of any tree, our empirical results match precisely what previous results had predicted.

Conversely, our results also strongly challenge the evolutionary timescale (fig. 2). Rather than confirm a history for humanity that stretches back hundreds of thousands of years, these results reject this hypothesis. If men have been around for hundreds of thousands of years, they should have accumulated mutations 8- to 59-times the amount currently observed. Instead, we observe only a few thousand years’ worth of mutation accumulation.

Furthermore, the combined results from mtDNA (i.e., Jeanson 2013, 2015, 2016) and Y chromosome (i.e., this paper) analyses represent two independent lines of evidence—maternal ancestry and paternal ancestry—that reject the evolutionary timescale for the origin of humans. Together, these two datasets falsify the current evolutionary model for humanity."

    Hello guest!

Interesting exploration which ties in genetic clocks to the Bible. This area is something not many JW's dig into as they aren't young earth creationists, however that being the case, the case still needs be made with regard to Noah, his sons and their wives as the sources for all who are currently alive. One would expect that there would be a way to corroborate these expectations, and this paper (there are others) along with the video series (I pulled out the two foundational episodes) for reference (I haven't finished them all or read the supporting literature) are an effort at this. So this post is stub for me to go back to for reference as I go through the material.

Thank you.  I referred to this kind of study when speaking to AlanF on this forum and he continuously called me an idiot. There have been other studies as well which prove that the number of mutations at the steady level of degeneration of DNA - the math of it - implies that if mankind were as old as they say we are (billion years)....... the number of DNA mutations (because they are overwhelmingly negative and not positive) would have seen the extinction of humankind a long time ago.

There are some good videos online that deal with this.  I answered Dawkins on his video with the long neck of the giraffe many years ago. Gave a long spiel. The artery that goes up the long neck and the nerves indicate the opposite of what he was saying. He is a nasty piece - as are most militant atheists I have come across.

    Hello guest!

I just watched this documentary on amazon. It's a good overview of the material. The manner of presentation is perhaps more evocative than simply reading some papers.

Exactly. I think one paper scrambling to deal w/this is this one:

Thanks for that xero, but I've always thought that if evolution were a real thing, we should have the X-men for real by now:)

It's my own fascination to be certain. I like to take as many things out of the realms of the philosophical and theoretical as I can.

I have the same type of mindset.  I also listened to a few podcasts featuring the high priest of Evolution (dawkins) and some other debates.  One learns a lot.

Dawkins is such a jerk. If you read "Climbing Mount Improbable" you'll realize he didn't. Instead he wastes your time trying to distract you from the fact that nothing he's provided has even begun to scale that mountain.

I have an old book that deals w/the math. It's "Darwin Was Wrong - A Study in Probabilities". Very hard to come by, but really quite clear in its explanation of the mathematics and biochemistry involved in any attempt to create life in all its varied forms.
