Hunting in savanna-like landscapes may have poured jet fuel on brain evolution – Study

Ever wonder how land animals like humans evolved to become smarter than their aquatic ancestors? You can thank the ground you walk on.

Northwestern University researchers recently discovered that complex landscapes — dotted with trees, bushes, boulders and knolls — might have helped land-dwelling animals evolve higher intelligence than their aquatic ancestors.

Compared to the vast emptiness of open water, land is rife with obstacles and occlusions. By providing prey with spaces to hide and predators with cover for sneak attacks, the habitats possible on land may have helped give rise to planning strategies — rather than those based on habit — for many of those animals.
