DARWIN’S LIZARDS



Text  



Via the Times:

There’s nothing like the threat of being eaten to make an animal evolve in double-quick time, a study of lizards has shown. Twice within a year the brown arole lizard has evolved changes in its body and behaviour to outwit a predator — confirming Charles Darwin’s theory on natural selection…They said that the findings counter the “widespread view of evolution as a process played out over the course of eons”. The evolutionary changes had been predicted by scientists after observing lizards on other small Bahamian islands, known as cays. The researchers introduced the predator lizard on to six islands in the hope of observing changes and establishing how quickly they occurred. Six more islands were kept free of the predator as a control for the experiment.
Or maybe that famous Intelligent Designer is a speedy, yet predictable, operator.
