The paired, lopsided maple seeds, with their odd propeller shape, are adapted for dispersal. That means that their shape helps them to helicopter away from the shade of their parent tree to find a sunny spot to take root. Without this advantage, when they fell to the ground under their parent tree, they might never have the sun they need to develop.
