Dolphin Brain vs. Human Brain: A Comparative Analysis
Dolphins and humans, two of the most intelligent species on Earth, have intrigued scientists for decades due to their complex behaviors and sophisticated cognitive abilities. While the human brain is often considered the pinnacle of evolutionary development, the dolphin brain presents fascinating parallels and differences that provide insights into the nature of intelligence. Size and Structure At first glance, the dolphin brain is notably large relative to its body size, a trait it shares with humans. This high encephalization quotient (EQ) suggests advanced cognitive processing capabilities. However, the structure of the dolphin brain differs significantly from that of humans. Dolphins possess a highly convoluted cerebral cortex, with more folds than the human brain. This intricate folding increases the surface area, allowing for more neurons and, potentially, more complex processing. The human brain, on the other hand, is characterized by its highly developed frontal lobes, which...
