also evoution is a vague term, not a clear cut definition.
its like a monopoly to claim everything mutates and changes to adapt.wihtout explaining how and why it happens.
also, doesnt explain how the species who died out, did they adapt wrong?
also what happened to the homo sapiens come from monkeys or neanderthals?
if creationist say humas eveolved from 2 homo sapiens, they arent wrong, even by evolution standards 
evolution can be a vague term. its more of survival of the fittest. like for examples, white moths vs black months in dark wooded area. black months would have better chance of survival so that moth will 'evolve' more into darker moth in that area.
species who died out is due to many different reasons. such as other predator species moving into a new area and killing off certain species. or change in climate/dietary change or like i explained before. different body color in certain environment.
scientifically there is no saying that humans evolved from monkeys. monkeys are CLOSE living relatives to human. and again lot of different causes of extinction such as lack of food, climate change, etc etc.
they recently found new human related species i forget the name but currently its not 100% complete. there are new species getting discovered and the ocean isnt still fully explored. many things are still in mystery.
