Scientists have proved one of Charles Darwin's theories of evolution – survival of the fittest – for the first time. A researcher at St John's College, University of Cambridge, found that mammal subspecies play a more important role in evolution than previously thought.
Evolution is not the survival of the fittest. It's survival of those most capable of adaptation to change.
Science can DISprove things, but (apart from math), science doesn't prove anything. There is always doubt/error-bars/probabilities.
To be fair, @Charliesey didn't make the claim, the article does: [sciencedaily.com]
@p-nullifidian . . .he didn't link to an article, and just because an article gets it wrong should not excuse anyone who cares about science and critical thinking.
