the intersection --- An issue that comes up in my field of paleontology which is relevant here is that in some point in earth history an ape starts walking upright and eventually some of the descendants of those apes become known as Homo sapiens, so when do we as paleontologists hand those fossils over to anthropologists? When do anthropologists start deferring to archaeologists? As disciplines we have developed ways to navigated these issues, but when discussing things more philosophically it's less clear. There's a moment where your two distinct definitions would in fact overlap, and I also think it's important to remember that humans are a part of the natural world, no matter how much we might try to remove ourselves from it. Food for thought.
