dont have time to find it. he basically says the 2% thing is an antiquated understanding that conflicts with recent ancient dna studies. Go watch the podcast [this video]

The current "Out of Africa" is really not the same as what you might have learned 2-3 decades ago, despite the branding. David Reich is probably the leading researcher in this field and his description of our best guesses is highly nuanced and open to new data. [this video] [LINK]
