Final answer:
Homo Neanderthalensis were well adapted to cold climates with their large brain size, wide nasal openings, and short and stock post-cranial physique.
Step-by-step explanation:
True
Homo Neanderthalensis were indeed well adapted to cold climates. They had a large brain size compared to modern humans, which allowed for complex cognitive skills. Additionally, they had wide nasal openings to help warm and humidify the cold, dry air. Their short and stock post-cranial physique helped to conserve heat.
