Duarte, I'm late, as always. ah ah ahDo not worry Salento. My male descandants will remember fondly the T's. LOL. It seems that the R's are more fertile and had more success than the T’s in propagated their lineage. :grin: But I've heard, I don't know where, that the "Y" chromosome is in extinction. I believe we will all become archelogical relics.:sad-2:

Fertility? Come on! I'm sure you're kidding, but here we go. There are people who think it's about that. As you likely know, I'm affraid it hasn't necessarily to do with physiological fertility. As you likely know, too, the frequencies we see in Europe nowadays largely result from ancient movements/replacements and correlations (see articles below), some of them at times of lower population (which in even earlier times certainly favored extinctions, especially when it comes to Y hgs - haplogroups), so I'd say the timeframe/context may be relevant to understand proportions. The population in Europe was low in Neolithic, and started to grow "exponentially" after ~2000 BCE, afaik. The decrease of frequency in Europe as a whole of haplogroups such T (and G) started even before, and it seems it was firstly associated to the relative increase of hg I, for some reasons not clear yet: wars/killing (see for instance what happened with hgs such Q in Americas), RH factor, climate change or diseases that possibly weakened first farmer societies, slavery and/or elite dominance etc. Later, perhaps similarly, they (now also hg I) were impacted additionally by the increase of R1 and probably J2 and E1b in Bronze Age, which are also "successful" lineages generally speaking. I1 itself expanded greatly in Bronze Age though, mainly in Scandinavia. Did I1 men suddenly become more fertile than I2? Hmm... Let's go further. What about R1b-A8039 vs. R1b-P312 (both under R1b-L151)? Or R1b-BY15512 vs. R1b-U152 (both below R1b-P312)? Sorry, not really. Fertility or akin don't explain phenomena like these:
"The forefathers of Europe: Two thirds of modern European men descend from just three Bronze Age leaders"
https://www.dailymail.co.uk/sciencet...e-leaders.html
"Half of Western European men descended from one Bronze Age 'king'"
https://www.telegraph.co.uk/science/...onze-age-king/
(They could have reinforced male line, since everybody in Europe must have granddaddies belonging to whatever "European" old haplogroup, but ok. We got it.)

So, continuing... already affected, those I mentioned at first were completely "absorbed" at some point, soon or later (it doesn't mean a perfect dilution over time; modern concentrations would be still related to ancient movements, geographical peculiarities etc., sure), and the substantial decrease in each case naturally must have ceased at some point, given the successive changes of context.
Due to the "demographic explosian" in the last thousand years and the huge population we have now, I'd say that the extinction of these older branches are unlikely. Very young branches naturally have more chances to be extincted soon enough. But I'm sure Salento will work hard to guarantee the survival of his more recent lineages. Ha!
Just kidding...
You're right in do not share. A love and a son in each port, like a sailor. You may not have met Adele in a London Pub. But there are many Adeles in London, Rome, Salento, and throughout the United States. Your matches on AncesryDNA may be a little more than just unknown cousins. LOL :grin:@Duarte That's why I don't share access with my DNA relatives on AncestryDNA :grin:
Who needs that ... LOL
@Duarte
Just thinking... Given this critical "nature" of Y-DNA, I guess in some sense all surviving hgs in each time have a portion of "success".
Also, how many lineages were collaterally saved by this huge population growth?
We're used to talk on factors that led to retractions, but at the end, in another perspective, the changes that culminated in Bronze Age may have indirectly caused the survival of many lineages, that otherwise would have been extinct. Some grew more, some less. Still, it's kind of an irony.
Amyways, we all own our existence to human past, the exactly way it happened.
Cheers

I now get Latin Tribe Ardea as a new sample, and it is right before Anatolian Copper age. I think these are the two most important samples I get, as I speculate it I am roughly a merger of these two groups, ultimately.
I used to get Copper Age Anatolian as my 4th sample by these settings, now it has been bumped down to 5, by Latin Tribe Ardea that took it's place.

"no matter the relative number of individuals in relation to the whole"Hello Regio.
You're right. All lineages that have survived to the present are victorious, no matter the relative number of individuals in relation to the whole. From a certain time in the humanitie history onwards, the growth of population density made the surviving lineages contribute to each other's mutual success. Hugs dear friend
