How elephants evolved to become big and cancer-resistant

All things being equal, large, long-lived animals should have the highest risk of cancer. The calculation is simple: Tumors grow when genetic mutations cause individual cells to reproduce too quickly. A long life creates more opportunities for those cancerous mutations to arise. So, too, does a massive body: Big creatures […]
