I was inspired to deviate form my usual posting on a specific paper, and to list some major "u-turns" in science recently:
- Group selection - at first a big no-no, now is become more widely accepted (but called multilevel selection).
- Population differences - AAPA said no biological basis for racial differences, now a rapidly growing field, in anthropology and medicine.
lesser u-turn:
- Multiregional theory. Out of Africa with complete replacement was assumed to be "more correct" for a while, now seeing more evidence of considerable admixture/continuity
Well, actually that's all I could muster up for now. There are probably many others, so I'm extending a wide open invitation to anyone who wants to propose more... just leave a comment.
