Brain Evolution

Brain evolution refers to the gradual development and complexity increase of the brain over millions of years, driven by natural selection. Early ancestors had simpler brains suited for basic survival, but as species faced new challenges, brains grew larger and more capable of advanced functions like problem-solving, language, and social behaviors. Major milestones include the development of the limbic system for emotion, the neocortex for reasoning, and specialized regions for language and memory. This evolutionary process has resulted in the human brain being one of the most complex structures known, enabling advanced cognition, abstract thinking, and cultural innovations.
