Final answer:

Neanderthals' brain size, evolution of brain size in hominins, and variability in brain sizes are discussed in this detailed answer.

Explanation:

Brain Sizes in Early Hominins

Neanderthal's brain size: Neanderthals had an average brain size of around 1,500 cc, larger than modern humans. However, it is important to note that brain organization and emphasis on different areas could impact intelligence.

Evolution of brain size: Over time, hominins evolved with brain sizes increasing significantly from earlier smaller sizes to a mean of around 1400 cc in modern humans, likely due to environmental pressures and competition.

Variability in brain sizes: Early hominin brain sizes varied greatly, with estimates ranging from 300 to 550 cc, showing a range within and between species.
