Beware of parsimony

Allan Krill

Beware of parsimony: it can kill a wonderful adventure story — reducing it to a single sentence. 

For example: Some chimps got isolated in an aquatic habitat on a barren volcanic island, and a few descendants escaped to leave early fossils, while others evolved further into humans, before spreading out around the world.

That simple model can explain all the evidence: human anatomy, physiology, paleontology, genetics, psychology (self-domestication), history. No one likes it, because it would kill many good adventure stories and many good careers.
