Sea Change

((Under Construction))

Sea Change is a profound or notable transformation. This timeline will be looking at a plausibility where a splinter branch of the genus "homo" adapted to life in the ocean, creating an arguably sentient race of merpeople.

Note by Author
This timeline will focus heavily on evolutionary biology at first then will be looking into accounts made by humans of the timeline. While I want this timeline to be based in real world science I will be making three slight adjustments in order to have a compelling series of articles, Other than that, scientific plausibility is the name of the game.
 * 1) The Merfolk have upper-bodies morphologically similar to humans.
 * 2) The Merfolk were able to evolve Cetacean-like lower bodies much quicker than in OTL.
 * 3) The Merfolk of this timeline never go extinct as a species.
