I want to know the answer to the following question:
When did people first start arriving in the European continent?
All the background I'm provided with is that "The most important demographic influence in the modern Portuguese seems to be the oldest one; current interpretation of Y-chromosome and mtDNA data suggests that the Portuguese have their origin in Paleolithic peoples that began arriving to the European continent around 45,000 years ago.". Is that enough to answer the question?
Answer: yes
