Has anyone ever looked these 2 items up and found a bevy of convoluted answers? It seems that no one can clearly define the difference, or what is more disturbing is that perhaps, they don’t think there is a difference. It seems to me that what Darwin discovered was adaptations and that somehow was extrapolated into believing that we all evolved from single cell organism with a lose explanation of where these single cell organisms came from. So I’m asking someone to please explain evolution. Does anyone really think that humans are a result of billions of years of changes from single cell creatures? Why would humans be considered an evolutionary step in this world of hostile environments?

Here is what seems to make it implausible to me simply on the level of adaptation and differentiation and I’d like to know if there is anyone who can answer these specific questions. I’ve read that we probably share a common ancestor with the chimpanzee and I’m guessing that no one knows what that common ancestor is or more precisely, we have not found ancient remains of this creature. Does this make sense when we think about what we say has happened? What would drive the divergence? What would make a species that is comparably hairless, with poorly developed senses (no eagle eye, dog like hearing or sense of smell) and physically weaker an adaptation or evolutionary selection? 

From what I have read, we have lots of “early human” remains but almost no ancient forms of chimpanzees or other primates. I guess this is because we are somewhat self obsessed? What makes an “early human” an assumed ancestor? My understanding is that Neanderthals were once thought to be an ancestor and then they were found to have gone extinct however, later they decided that Neanderthals probably mated with other humanoid creatures and their DNA is in fact preserved in humans. Why would a creature like a human evolve from creatures that are clearly better equipped to handle nature and more likely to maintain the ecological balance on this planet. Why are we here?
