Genetic variation study reveals Darwinian evolution may be four times quicker than expected.
More genetic variations in a species speed up evolution as weaker features die off and stronger ones take over.
The study's authors called it the "fuel of evolution" and looked at 19 wild animal groupings throughout the globe.
This data analysis found this raw material for evolution is more plentiful than prior predictions
we may have to revise our expectations for how rapidly creatures develop - an important subject in our era of climate change.
"The technique measures the potential pace of current evolution in response to natural selection across all features in a population,"
