Framed tortoise shells are seen hanging on the walls of Turing's home. This is an allusion to his later work showing that the patterns on tortoise shells, despite their apparent complexity (and beauty), can come about from a rather simple set of rules or instructions, i.e. the underlying genetic code. This convinced Turing that exceedingly complex biological entities can stem from simple programs, i.e. from simple changes in the DNA. This insight has profound implications for evolution, especially to those arguments asserting that the complexity of life could not have arisen by chance alone.
