Animal Senses
5—Evolution of Senses
In July 1858 the first papers of Charles Darwin and Alfred Russel Wallace on evolution by natural selection were read in London. In this final programme on animal senses, Professor P. B. MEDAWAR and Dr. W. E. SWINTON talk about the process of natural selection, which has given rise to such highly developed abilities as the sight of owls, hearing of bats, and the electric organs of certain tropical fish.
