Amgen senior scientist Kevin Corbit, writing in the New York Times:
Millions of years of evolutionary experimentation have produced genetic adaptations that enabled bears to cope with obesity, converting it to a benign state in which weight gain has much-reduced health threats. If nature has figured this stuff out for grizzlies, maybe we can for humans.
I salute Kevin’s optimism. My understanding is that there is a long path from knowing how a mechanism works in other animals to making use of it in humans.
But every path has a first step!
