I found the discussions on genetics particularly interesting.
DNA studies continue to overturn a lot of long-held beliefs, and there were a couple of points discussed in the show which I would say might be on a bit of shaky ground given what we now know about genetic history.
This study of UK genetics by Oxford University, for example (
Genetic study reveals 30% of white British DNA has German ancestry), found that there is no Celtic DNA group, notwithstanding that there are of course cultural similarities between (say) the Welsh and the Scots. According to the article, "Surprisingly, the study showed no genetic basis for a single “Celtic” group, with people living in Scotland, Northern Ireland, Wales and Cornwall being among the most different from each other genetically." That I would proffer supports an argument that, if folk with Celtic ancestry are more likely to be experiencers, then the vector for this is actually cultural rather than genetic.
Another study I found interesting was this one,
Americas’ natives have European roots, which found that Native American DNA has a significant Native European content, up to 38% in some cases. That's not DNA as a result of interbreeding that's taken place post-Columbus, but rather of much older origins. In a nutshell, the folk that crossed the Bering Strait and populated the Americas were already a European, West Asian and East Asian genetic mix. If you take (say) one third base European DNA, then boost it further with the mixing that's taken place in more recent generations, you start to arrive at levels of European DNA in modern Native Americans comparable to what you find in large chunks of European countries' populations. Again, where there is a higher likelihood of experiencing paranormal phenomena, my argument would be that cultural rather than genetic factors play a much greater role.
Just a bit of light food for thought for a Monday morning.
