About this reel
This video delves into a hypothetical scenario where human blood changes color, revealing profound impacts on our biology and cognitive function. The narration begins by questioning why blood is red and then explains how hemoglobin's iron content makes it reflect red wavelengths when carrying oxygen. It contrasts this with hemocyanin, found in horseshoe crabs and octopuses, which turns blue due to copper-based molecules. The video further explores the inefficiency of hemocyanin at human body temperatures, suggesting a need for significant physiological changes like reduced metabolism and brain size if humans relied on it. This content is perfect for science enthusiasts who enjoy thought experiments about biology and evolution.
