How does this discovery fit with so called Eve the Earth Mother traced through her Mitochondrial DNA?

There seems to be 140,000 years difference. Could this Y-Adam be linked to Neanderthals or as Genesis describes, the Giants of old, men of renown.

I think it has to do with Y chromosome DNA, since that’s what’s passed on from father to son.

Mitochondrial Eve is through the DNA in the Mitochondria.

We only have a minuscule percentage of the puzzle pieces on the table.

There are a lot of pieces between this guy and any of the known founding Eves.

We know roughly where the pieces need to be to put the puzzle together, but we also know there are a lot of blank places on the table, we know the missing pieces are scattered in various boxes in the attic, the basement, next door and that well over half of them got lost in various moves from here to there.

We know it’s a family portrait, we have a vague idea of the background, we don’t know exactly which family members sat for the portrait, and there are enough puzzle pieces in the boxes to make a couple dozen portraits, landscapes, pictures of trains and Parisian cafés.

Other than that, it’s a simple matter of putting the puzzle together...

Men who have no children or only daughters don't pass on their Y chromosome.
Women who have no children or only sons don't pass their mitochondrial DNA to their grandchildren. (Theirs sons have it but they can't pass it on.)
This man is one who happens to have unbroken lines of male offspring until present time. There must be somebody like that. If you go back in time far enough, there is presumably only one, a great-to-the-n'th-grandfather of all presently living men.
All other Y chromosomes from his contemporaries have been lost.
There can of course be many generations before him.
Similar for women. These "Adam" and "Eve" characters may never have met, could be separated by thousands of years and miles.
This is true for every other chromosome as well, even though they jump between the genders.
Eventually they'll try to estimate an age of an original ancestor for each of them too.

or as Genesis describes, the Giants of old, men of renown.

First thing I thought of when I read this.
