The Attenborough series of the evolution of life from pre-Cambrian to modern is called Life on Earth. Unfortunately it was made in 1979, so it is a bit dated in places (e.g. the old reconstruction of Hallucigenia). Even more unfortunately modern telly will not support a series that has several episodes before you lay eyes on a vertebrate (Sir David excepted).
