The second quote suggests mating between different forms of humans led eventually to sapiens, and rainforests were only one type of habitat where they mixed. I don’t know how this solves the problem of sapiens’ origin. Or why it should disqualify the savannah theory. Maybe sapiens originated in the savannah and spread his seed in other environments, including back in the trees from which he descended. But I’m only asking for clarification of the statements made in this article. Did sapiens evolve from different homos mating, or did “readymade” sapiens mate with different homos?
