These are timelines dealing with various alternate developments of evolution of life on Earth. Most of the timelines of this sort are rather short and conceptual here on AH.com, some are longer though. Some also overlap with timelines about alternate agriculture, in cases when they deal with slight changes in the OTL evolution of viable crops or domesticable animals, offering potential ATL outcomes.
