New human species found in Siberian cave

The researchers found that the individual was female and came from a group of hominins that shared an ancient origin with Neanderthals, but subsequently diverged. They call this group of hominins Denisovans. Unlike Neanderthal, Denisovans did not contribute genes to all present-day Eurasians. However, Denisovans share an elevated number of genetic variants with modern-day Papua New Guinean populations, suggesting that there was interbreeding between Denisovans and the ancestors of Melanesians. Very interesting. Thank you for sharing this.

The shoulder joint evolution in humans allowed overarm throwing of spears which gave such a tactical advantage that they dominated the other human species. That's evolution for you.

another evolutionary dead-end like Neandertals?
