Marsupials. What a cool evolutionary track! From the Marsupials Wikipedia page: "Marsupials have an extremely short gestation period (about 4–5 weeks), and the joey is 'born' basically in a fetal state. The blind, furless, miniature newborn, the size of a jelly bean, crawls across its mother's fur to make its way into the pouch, where it latches onto a teat for food." The whole article is interesting. Here are some pics I took of the kangaroos at the zoo in Munich, Germany.
