Question

What are some discoveries or relative scientific findings by neanderthals?

Answer 1

Not necessarily scientific, but what I always found fascinating about the Neanderthals was that they were the first known group to bury their dead with grave goods and flowers.  This may have meant they believed in an afterlife, even that far back in time.

Answer 2

Amazingly intelligent:

Please try not to be racist against other branches of humanity.

Answer 3

Science means the use of the scientific method.  The neanderthals did not have the scientific method.
