Sifu, you are right about calling for experts to come and look, and not just use such a wonderful find as a money-making exhibition.
Nor would I try to kill one if I did find it, unless it was life-threatening; but I would be taking pictures if I could. The problem that I see with that, is that there are already a lot of pictures, some of which DO look very real; but no one can have positive proof of a living neanderthal just from a picture.
It will take an actual body, either of a dead one found, or by someone who does actually shoot one; so it can be studied.
I am pretty sure that this is just a hoax, and the person that is promoting the supposed Bigfoot, is also known for an earlier Bigfoot hoax.
However, I think it would be amazing if one were actually discovered and could be proven to be real. The stories of Neanderthal developing along side of Homo Sapiens are very intriguing, and the possibility of more agressive early humans driving the Neanderthal into seclusion, could well have become the result, leaving us with not one, but two humanoid species here on earth.
A discovery of this nature could completely re-write our world history.
