Early in his career as a geologist, Dougal Dixon developed an interest in fossils and paleontology. But he took that curiosity in a unique direction. Dixon has published several books on speculative evolution -- imagining animals that may have evolved if conditions were different. Pictured above is an illustration from one of his books depicting a future version of humanity:
In Man After Man, genetically superior humans abandon a polluted Earth to colonize space. The remaining Homo sapiens tinker with their gene codes for a thousand years to achieve immortality. One such species is the Tic, who graft back-up organs and limbs onto their bodies like Mr. Potato-Head made flesh.
