Snake uses its split jaws as a knife and fork

Many animals use their limbs to handle their food and obtain edible pieces from it. To take a relatable example, we humans peel fruits, fillet fish, and break crabs with our hands and tools. In contrast, most animals that lack limbs (like snakes) would be... click to read more

The puzzling history of South American mammals

When the Isthmus of Panama formed, it connected North and South America, allowing the interchange of the previously separated faunas from two continents.
