Answer:
humans had more developed 'social' brains than Neanderthals, which enabled us to colonize new habitats and adapt to climate fluctuations
Explanation:
A more developed brain is considered to be an adaptive advantage that enabled early humans to leave Africa and colonize new habitats. Modern humans are able to adjust to new environments, situations, and socialize with other humans because the brain is a social organ. Although Neanderthals were able to occupy an important area of Europe, H. sapiens could colonize faraway lands, migrating into tropical forests, deserts, and glacial lands (colder areas than those colonized by Neanderthals). These early humans formed social groups which enabled them to find food more easily, thus greatly increasing their chances for survival.

Explanation:
Timulus discrimination is the tendency to lack a conditioned response to a new stimulus that is similar to the original conditioned stimulus. A higher order conditioning occurs when a neutral stimulus comes to act as a conditioned stimulus when combined with another stimulus that already evokes a conditioned response.
Its brain
Like the rest of our organs, the brain undergoes its own aging process. And yet the majority of adults don't experience major cognitive decline—the kind that severely limits their ability to live independently—over time. That's because the brain is one of the most resilient organs in the body.
