Final answer:
Neanderthals had physical characteristics such as a stocky build, rounded skulls, pronounced brow ridges, and large brains. They were adapted to cold climates with features like a large nasal cavity, occipital bun, and large front teeth for chewing on leather. Neanderthals had well-developed muscles and were able to throw projectiles and use spears.
Step-by-step explanation:
Neanderthals were a distinctive form of humanity with physical characteristics such as stocky build, flattish and rounded skulls with pronounced brow ridges, and larger brains than modern humans. They were adapted to their environment, particularly in cold climates, through features like a large nasal cavity, occipital bun, and large front teeth for chewing on leather. Neanderthals had well-developed muscles, which allowed them to throw projectiles and use spears. Their ability to survive in cold conditions was a key asset during the ice age that occurred around 100,000 years ago.
