Neanderthals

Even though you probably won't read this:*Ceolocanth, which most scientists use to think went extinct several million year ago, are still living in the Indian Ocean, off the coast of Africa and Madagascar. Finding a livining plesiosaur wouldn't really disprove evolution. You'd have to find 4 billion year old turkey and people fossils, to disprove evolution.*Neandertals (probably) couldn't survive in warm weather well, because of their nasal cavity. Here's a hypothetical extinction scenario:
Neadertals begin to run out of food, so they move to a new area. Because warm weather is bad for them they go North. They chase their prey further North until their food supply is exhausted. During the ice ages the weather becomes colder, so they can look for food in more Southern regions. After the ice ages the weather becomes warmer and they die of various diseases.*Another extinction possibility: Our ancestors begin trying to farm, and the Neadertals, who are nomadic wander through their fields and eat their food. So whenever they see a Neandertal they kill it, just like farmers nowadays do to insects.*In response to the original post: Neandertals are more like people than monkeys. Them having a "soul" and being creative isn't really surprising. Some people used to think of Africans and aboriginals as animals.
