Could myths about "trolls" be referring to Neanderthals?

Could myths about "trolls" be referring to Neanderthals?

We'll never know, will we?

It appears that, over much of prehsitory, in many parts of the world, different species of Homo coexisted. Who knows what our ancestors thought about those 'others'? Encounters with them may lie at the root of a thousand myths and legends.

But unless some genius invents a time machine one day, we shall never know.

You Racist! According to a DNA test I have some neanderthal DNA, and that you would call me a troll is offensive. I am more outraged than a feminist in trump's locker room!
