The facts of evolution used to be disputed because of the 'missing links' in man's descent. This programme shows how recent discoveries have now largely filled in these gaps in the family history of man.
Scientific advice has been given by Professor W. E. Le Gros Clark, y.R.s., who speaks at the end of the programme.
