Why do avocados have such big seeds? Sometimes they're all seed, no guac.

The pit's designed to reproduce the parent tree, not to please you. The wild avocado grows in subtropical jungles, so the new sprout has to get several feet tall before it can share sunlight (to make food) with its neighbors. Until it grows out of their shadows, it relies on nutrients in the seed, so it'd better be big.
