When a warmer climate spread across the globe, the woolly beasts were in deep trouble. Melting snow together with predation by humans made the animals extinct. Their numbers dwindled to zero in 6,000 years. A strange thing happened during this time. The species tried to adapt and threw up countless mutations. Most were destructive. | ▶ optimum not news. | mutations killed animals ◀ |
These changes are now known from two specimens in Siberia. One on the mainland and another on a rock in the ocean. It was the slightly later Wrangel Island specimen that had an over representation of genetic mutations. Those who want to save threatened species must now be careful. Inbreeding could bring about the mass genetic alterations and that kills off endangered animals. | ▶ | not. | ◀ | ▶ | not | ◀ |
