Summary

DescriptionUnnatural selection, 2 heads, one species.jpg	English: Canis lupus. Each skull was photographed from the——same focal distance with a fixed zoom; the images were then combined while preserving scale. The larger skull is from a wild grey wolf. The smaller is from a chihuahua. They are in fact considered the "same species." The domestic dog is the product of artificial selection over many generations. Suitable example for evolution. Or general biology.
