Textbook Question
Chapter 43.1, Problem 1CC
Scientists have determined that the brain mass of Homo neanderthalensis (Neanderthals) was greater than that of our own. Does this mean that Neanderthals were more intelligent and capable of more complex behaviours than we are?

Some scientists suggest that the Neanderthals and possibly Denisovans, never went extinct, but instead where assimilated into Homo Sapiens. What evidence would you look for to support this hypothesis?
Research shows that Neandertals coexisted with at least three other species, including Homo sapiens. There are some humans today that have Neandertal and Denisovan genes.
Generate a hypothesis about how their genes are also a part of our genes.
Taphonomic analysis of Neanderthal remains has found that they have a pattern of trauma similar to that seen in modern-day rodeo riders. This was interpreted to mean that Neanderthals:
A. Had projectile weapons and could hunt large game from a distance.
B. Were riding large animals like horses and reindeer.
C. Had hostile interactions with modern humans migrating into the area.
D. Were a war-like species that fought amongst themselves a lot.
E. Had to hunt large game at close range.
