Some tales have it that black swans were first white, and due to eagles, lost their feathers in battle and were left naked...but crows come along and to spite eagles, gave their feathers to the naked swans and that is how they became black. I guess there is a little lesson in there about 'donning the features of another' in order to behave like another...but in this instance, there would have to be some kind of similarity between crows and black swans in order for the connection to be made other than colour. I don't know the lifestyles nor habits of either, so can't offer an observation unless I dig real deep into Aboriginal myth and specifics of both birds...and what people do as natural behaviour that mimics both or either.
I did find something interesting aside from this though...spears found in Germany that are about 400,000 years old. I had pondered how any creatures may have been caught other than stoned to injury or death, or found injured and caught. Spears...the ability to not only make a spear but professionally use one goes a long way in how early man developed and became a powerful species, not only against creatures for food or survival, but also as being a dominant force against other tribes of early man. If one can competently and confidently protect one's self, then one can explore far outside their domain, and certainly learn about the habits etc of other tribes of early folk.
I guess following natural resources for foods and general curiosity of the surrounds wasn't the only thing that spurred folk to go where they could...they could protect themselves quite well. As spears so old were in use, I wonder if the simple sling was also in use, firing projectiles further than an arm could do...or atlatls in their way for both rock and spear.
Anyways...being able to be proficient in bringing down a certain creature would certainly make one associated with that creature amongst fellow tribes-folk, and I guess that may be the early beginnings of totems. But that doesn't really help with Denisovans now, does it. Or does it? They had different DNA compared to others...and thought differently...but they did evolve from their ancestors. I wonder...what does Germany offer in the way of genetic similarities to Denisovans? Or anyone from near Germany...hmm...I might have a look into that.
