Reading the book "Kindred: Neanderthal Life, Love, Death and Art". I've some reservations about the level of detail and the rather literary preludes to each chapter, but the gist is eye-opening. Science has learned so much more about Neanderthals than I realized. Modern technology has enabled very detailed reconstructions.
The bottom line is the species knew what they were doing.
That doesn't mean that Gov. Abbott knows what he's doing.
