So I have recently watched this YouTube Video, which basically suggests that the Neolithic Revolution (which included the rise of agriculture) in Britain, as well as in Scandinavia and parts of Northern Europe might have been caused by people fleeing from the sinking Doggerland.

The topic is really interesting to me, but I'm kinda skeptical about it since the video doesn't stated many sources. So I'm asking if any Archeologist, Historian or anybody else knows something about this topic.
