The winner of the Theos competition for the best 'tweet' of On the Origin of Species was announced last week.

Charles Foster's entry was: "He who dies, loses. He who reproduces, plays the game. He who produces game-playing offspring who won't submerge parental genes, wins."

The originality and accuracy of Mr Foster's entry impressed judges. In the competition, the public were invited to encapsulate the over 600-page seminal work into 140-character tweets on the popular Twitter website.

Theos received a wide range of entries (not all within the rules), including:

Velizou: thinks that #darwin would have had a much larger impact if he'd discovered #evolution 150 years later... with or without #twitter.  

shanu8:If man evolved from monkeys and apes. . . why do we still have monkeys and apes?

There was an old man from Kent

Whose thoughts, evolutionarily bent.

Some species live,

Some species die,

But none to heaven are sent. (John, on Times blog)
