When ice sheets marched across North America 20,000 years ago during the Last Glacial Maximum, they devoured liveable areas for caribou and isolated them from their Eurasian relatives for thousands of years. Now researchers have evidence that such…

Lyme bacteria show that evolvability is evolvable
Nature Natural selection favours those with a greater capacity to generate genetic variation. Some gamblers succeed by spiriting cards up their sleeves, giving them a wider range of hands to play. So do some bacteria, whose great capacity for genetic variability helps them evolve and adapt to rapidly changing environments. Now research on Borrelia burgdorferi, the…
