Once in a while a strange skull, skeleton or body is found that seem to be from a humanoid being, sufficiently different from a normal human being that we can say that it might belong to a different human-like being. Are they from other intelligent beings living on this planet (past or present), or are they from true extraterrestrial beings who died here because they couldn't breathe our air? Is it possible that a more advanced civilization in the past experimented with genetic engineering that led to the existence of small groups of very different human, or humanoid, beings?
