Who were the first modern humans to settle in Europe?

Before modern humans settled definitively in Europe, other human populations left Africa for Europe beginning approximately 60,000 years ago, albeit without settling for the long term. This was due to a major climatic crisis 40,000 years ago, combined with a super-eruption originating from the Phlegraean Fields volcanic area near current-day Naples, subsequently precipitating a decline in ancient European populations.
