Did you know that newborn babies can see only BLACK (darkness) and WHITE (illumi- na4ons by all sunlight's wave lengths) un4l the infant brain can grow to interpret what wavelength their cones are picking up. A%er about 5 weeks of life, babies can dis4nguish first, the color RED, and in about 5 months, a baby can dis4nguish all the colors of the rainbow that an adult can. Similarly, other creatures have developed sensi4vity to what wavelengths enabled them to func4on. For example, today we know that your pet dogs and cats are not color blind. Whereas humans have 3 types of cone cells in their eyes ac4vated by all colors of the rainbow, your pets have only 2 types.
