Kryocene Human

Kryocene humans are a group of former fictional species of human that are smarter than common humans and are friendlier to the environment than humans as they have cleaner futuristic technologies to protect environments and wildlife. Lesser Kryocene Human (Homo Sapiens Allos on the top middle) is a species that is 0.2% smarter than common humans. Mongman (Homo Rectrocarvatis on the top right) is about 0.5% smarter than common humans and has a short tail (unlike most other apes, which usually don't have tails). Common Kryocene Human (Prohomo Quadrobipedas on the bottom left) is about 0.6% smarter than common humans, while it walks in a similar fasion to theropod dinosaurs (hence its scientific name), it has a longer tail than a Mongman. Greater Kryocene Human (Prohomo Eogigas on the bottom middle) is about 0.9% smarter than common humans and is a fully quadropedal species, so it resembles a dog more so than its ancestors. Giant Kryocene Human (Prohomo Gigas on the bottom right) is about 2.3% smarter than common humans and it has large saber teeth as well as short mane on its neck and a carnivoran-like locomotion, giving at a gorgonopsian-like appearance. Fortunately for common humans, they are omnivores and feed only on the same food as humans, as well as eating insects, fish, frogs, small reptiles (even lizards and turtles because are immune to trichinosis, pentastomiasis, gnathostomiasis and sparganosis which common humans aren't immune to), eggs, small birds, small mammals, and carrion. They are currently found in the fictional future world and in real life North America.
