Were Celts once 30-40% of Europe's population?

[Aren]

By "Celticized" do you mean that they were autosomally 0% Proto-Celtic? Or something between 1% and 99%?

Are Mestizo populations in Latin America "Hispanized" Native Americans? Well, not exactly.

Most likely very little input. How much non R1b-L21(not counting U106 ofc) do Irish have for an example? Proto-Celts were most likely U152.

[Peterski]

Proto-Celts were most likely U152.

Why do you think that all of them belonged to just one haplogroup (or rather to one clade of one haplogroup)? IMO that's very unlikely.

BTW, some part of U152 is surely Proto-Italic rather than Proto-Celtic.

I don't rule out certain other non L21 subclades of P312, but U152 seems to be quite common in most of the "La Tene" area.

[Peterski]

Why do you rule out L21 as Celtic? And what about certain subclades of U106, could some of them be Celtic too?:

Maybe Proto-Celts expanded already in the Bronze Age, and old theories about Iron Age Proto-Celts are wrong.

Haplogroups aside, Centum speaking Celts/Tocharians were probably the original Indo-Europeans with Slavic being influenced by Scytho-Sarmatians, southern Europeans by native Etruscans for example and Germanic by indigenous Nordic speakers(possibly Finno-Ugric)

Also interesting that the Centum 'th' sound in Europe only exists in Britain, Iberia and Greece today.

Just a stupid theory of mine

From what I understand U152 is associated with the classical and archaeological Celts of Hallstatt and La Tene of the continent, particularly around the Alps and on the Rhine. The early Italics were an offshoot of this same group of people (prior to Hallstatt times there was a theorized Italo-Celtic language.)

That said L21 and DF27 represent other branches of Celts who went to Britain and Iberia respectively...they both spoke Celtic languages, shared Celtic gods with the Hallstatt/La Tene/Gaulish Celts, etc, and all would later adopt elements of the core Celtic Hallstatt/La Tene culture. They were all certainly Celts, genetically (with varying mixtures), linguistically, culturally, and religiously.

L21 arrived to the British Isles already with the Bell Beakers, way before Proto-Celts even existed.

Actually I think it arrived with the Food Vessel Culture (those were not Bell Beakers proper):

And the oldest R1b-DF27 in Iberia (from Valdiosera et al. 2018) is from the Cogotas culture:

Doesn't the oldest R1b-M269 in Britain predate that culture?
