Description
English:
  • The smallest animals have young that are proportionately enormous relative to the adults. The figure shows that hatchlings of the smallest snakes are one-half the length of an adult, whereas the hatchlings of the largest snakes are only one-tenth the length of an adult. Tiny snakes produce only one massive egg -- relative to the size of the mother -- which suggests that natural selection is trying to keep the size of hatchlings above a critical limit in order for them to survive.
