The wolves are exposed to cancer-causing radiation as they roam the wastelands of the abandoned city - with researchers finding part of their genetic information seems resilient to increased risk of the disease.
Alternatively put, the wolves that don’t have cancer resistance do not survive Chernobyl. I feel like this should be closer to the default way we talk about evolution.
That’s what natural selection is. We focus on those that survived because they developed resistance to something, but it has always meant that everybody else died and the species as a whole has moved forward.
Sure but the headline doesn’t say ‘natural selection caused . . .’ it straight up say ‘Mutant wolves developed resistance to cancer’ did they though? Or was that mutation already present and sudden environment changes cause the other ones to die off?
Cancer-causing radiations don’t cause wolves to develop cancer resistance, they cause wolves to develop cancer. Those that were more resistant survived, those that weren’t didn’t, now we have wolves that are different from those that we had before. They are mutant wolves, but the radiations didn’t make them mutants. The mutation happened before in some wolves, and their descendants survived better than those that didn’t have it. Evolution has always been like that.
