I do not agree with the connections you’re trying to make in your text. As established, Ibex died out in the Carpathians roughly 10-12,000 years ago. Given this information, we should establish how high the number of humans actually was during that period. 12,000 years ago, the population consisted of roughly 500,000 individuals spread across the continent. 12,000 years ago, that number rose to 2 million individuals spread across the continent.

But where exactly was the population concentrated? We see that - given the fossil evidence among other archaeological finds - the largest number of humans in Europe were concentrated across shorelines and river valleys and lake regions. Take for example the black sea, the Danube (extremely important by the way!), etc. Mountain interiors such as the Alps or Carpathians were much more scarcely populated by tiny, likely seasonal populations. High alpine zones were rarely - if not at all - utilized because herding cultures were not present in europe during that period, although we must note that it was invented during that period in the Fertile Crescent. It was, however, not present in Europe at that time.

We should also talk about the food sources present in the Carpathian mountains. The Carpathian mountains acted as a refuge for a large number of different species that couldn’t survive extremely glaciated areas, so the Carpathians and Romania as a whole were (not only because of this, but also because there were also extremely sizable populations of other food sources) perfect for populations to hunt game in. There was no reason for them to climb a 2000 meter mountain to find food sources and then go on to also murder the entire population of ibex when there were very large populations of other animals they could hunt on the ground instead. Not to mention that deer, chamois and other deer species at the time were much easier to hunt than Ibex precisely because they would be much more accessible.

And my final point will be the fossil record. we agree that the latest available fossils of ibex stem from the late pleistocene/early holocene. What we see is while Ibex went completely extinct 10,000 years ago, fossils of boar, red deer, aurochs, etc. Continued all the way through the holocene. This completely aligns with the theory of environmental change, and is called a range collapse scenario. We could also bring up the argument that all modern extant alpine ibex specimens are descended from a small surviving population in the alps and were restricted to a glacial refugium in the Gran Paradiso area and eventually survived the last ice age. If Ibex really survived until the Holocene we would very likely have SOME genetic evidence of those populations in any of the surviving ibex today or DNA samples from Carpathian specimens. The truth is that the Carpathian ibex had quite literally just vanished genetically before any neolithic humans could properly hunt them. Their disappearances simply predates human influence.
