Evolution of human colour vision opsins was increasing from 400 to 430. During this time, Ancestral Boreotherian had two long wave length opsins created by gene duplication, with one retaining the absolute max value of 560, equal to the ancestral value. This led to the creation of the modern human long wavelength sensitive, or red opsin. The other short wavelength sensitive opsin decreased its absolute max value to 530 and became the middle wavelength sensitive, or green-sensitive opsin. This occurred through mutations involving S180A, Y277F and T285A. The order that these mutations took place in the ancestral Boreotheria is currently not fully known. It is
Listen to What the Man Said and music are wedded together. Authors Roy Carr and Tony Tyler note about the song that "artful and sensitive production elevate what was originally a piece of inconsequential whimsy into what can only be described as High Pop", also describing the song as "likeable" and "hummable". Author Chris Ingham described the song as "superior pop". The song was also included on the numerous greatest hits compilations, including 1987's "All the Best!" and 2001's "". However, it was not included on the 1978 Wings compilation, "Wings Greatest". Listen to What the Man Said "Listen to What the Man Said" is a
