Evolution of human colour vision with limited colour vision. This is believed to have also been influenced by life styles, including being predominantly nocturnal. There is little data indicating the advantages of UV vision in early human ancestors. Early human ultraviolet vision, or ultraviolet sensitivity, included sensitivity in the wavelength ranges between 400 and 10. These wavelengths are shorter than visible light but longer than X-rays. In some rare cases, some modern day humans can see within the UV spectrum at wavelengths close to 310. In other animals that possess UV vision such as birds, ultraviolet sensitivity can be advantageous for courtship and reproductive success.
