Evolution is the first of two albums released in 1967 by British pop rock band the Hollies. It is their sixth UK album and peaked at number 13 on the UK Albums Chart.

The Hollies are an English rock and pop band formed in 1962. One of the leading British groups of the 1960s and into the mid-1970s, they are known for their distinctive three-part vocal harmony style. Allan Clarke and Graham Nash founded the band as a Merseybeat-type group in Manchester, although some of the band members came from towns further north, in east Lancashire. Nash left the group in 1968 to form Crosby, Stills & Nash, though he has reunited with the Hollies on occasion.
