Just a jump-off point for anyone not acquainted. It's a sprawling topic, as the 20k results of your search show! I'd also recommend Sweatman's research review: https://www.youtube.com/playlist?list=PLftb0lOpSe9PvJhFKSueZV9Wrz4g1qRkr https://www.youtube.com/playlist?list=PLftb0lOpSe9PvJhFKSueZ... 24 videos, 30-60m each, stepping thru over 120 papers. It's the most comprehensive synthesis I've found that actually deals with the debate. Sweatman is an advocate for the hypothesis, but he does an admirable job of focusing on the ideas and there's a lot to learn from him.
