What if the jews were black back in the days as slaves of the Egyptians? After escaping they mixed with middle easterners and later on with Europeans. The curly hair, the lips and their smell is very suspicious.

My own thoughts:
I do think the idea that Jews "up-bred" themselves especially with European DNA is very likely a strategy. The Romans and Greeks regarded the Jews as being the "dregs", the garbage, of ancient Egyptian society. So they could originally have been some kind of mixture, maybe even with some black.

It’s not a topic I’ve explored, but I would not dismiss it out of hand either.
