This is a deep dive into the details of how Neanderthal ancestry is patterned across ancient genomes of modern people. A wave of mixture starting in the Near East kept mixing as long as the expanding group kept meeting Neanderthals, from France to Central Asia.

Tracing the wave of Neanderthal-modern interactions
A rapid expansion of modern people ran into Neanderthals and mixed with them nearly to the ends of their range.

My ask of any science enthusiasts who tell the story of Rosalind Franklin:
Don't make her life be about the DNA debacle. She died far too young, but she was a promising scientist in her own right, a mentor and scientific author.
Not for Watson or Crick, but for her legacy.

Franklin was no victim in how the DNA double helix was solved. An overlooked letter and an unpublished news article, both written in 1953, reveal that she was an equal player.
