Color vision is a remarkable sensory adaptation that has evolved independently in various animal species. It allows organisms to perceive and differentiate between a wide range of colors in their environment. The evolution of color vision can be traced back to the ancestral vertebrates, which likely possessed only two types of photoreceptor cells sensitive to different wavelengths of light, allowing them to perceive light and dark, a condition known as dichromacy. Types of Color Vision Dichromacy Dichromatic vision is the most basic form of color vision characterized by the presence of two types of photoreceptor cells sensitive to different wavelengths of light. These two types of photoreceptors are typically tuned […]
