Answer :
Final answer:
Homo Neanderthalensis, or Neanderthals, were characterized by their large brain size, pronounced brow ridges, and robust physique. They had unique skull features such as an occipital bun and a large nasal cavity. Their large front teeth showed significant wear, suggestive of their diet or usage as tools.
Explanation:
The defining features of Homo Neanderthalensis, commonly known as Neanderthals, are characterized by several distinct anatomical attributes. Notably, they possessed a large brain size, which averaged between 1,200 to 1,400 cubic centimeters, comparable to the range of modern humans. They had a robust physique, indicated by features such as a broad scapula and a robust humerus, suggesting a well-developed upper body musculature.
Another notable feature of Neanderthals was their pronounced brow ridges, hinting at distinctive skull characteristics. These included an occipital bun at the back of the skull, and a large nasal cavity. Their large front teeth showed excessive wear, possibly due to their diet or usage of teeth as tools.
Overall, the key defining features of Homo Neanderthalensis centered around their large brain size, pronounced brow ridges, and robust physique. These distinctive anatomical traits set them apart, making them an intriguing subject of research in understanding human evolution.
