<2> The Evolution of Brain and Intelligence: A Complex Story of Adaptation and Development
<3> Introduction to Brain Evolution
The human brain is a complex and intricate organ that has evolved over millions of years to enable us to adapt to our environment, find food, and form social connections. Understanding the evolution of brain and intelligence is crucial to grasping the intricacies of human behavior and cognition.
Healthline suggests that the human brain is made up of billions of neurons that communicate with each other through electrical and chemical signals. This complex network of neurons allows us to process information, learn, and remember.
<3> The Emergence of Brain Structure
The earliest human-like species, such as Homo habilis, had a brain size of around 600-700 cubic centimeters. This was significantly smaller than the modern human brain, which has a size of around 1300-1500 cubic centimeters. However, even with a smaller brain size, Homo habilis was able to use tools and exhibit basic problem-solving skills.
Mayo Clinic notes that the brain’s structure and function have evolved over
