The Neanderthal traits are no longer found in humans, the last known being 24,000 years ago in Portugal. However, extensive research has shown the similarities between Neanderthal and human.
The Neanderthal cranial capacity was much bigger than modern humans, judging by the size skulls found from the Neanderthal era. This indicates that the Neanderthal had a possible larger brain size. The Neanderthal is known to be smaller than modern humans and only got to around 40 years old at most.
