When I was a kid, I was taught that animals knew everything the moment they were born. Today, it’s known that many animals learn important skills from their parents (usually their mothers).
Like humans, the first “food” other baby mammals(哺乳动物) get is their mothers’ milk. After a period of weeks or months, it’s time to eat meat. At first, adult animals like wolves bring back killed animals, so babies can eat easily. As babies grow older, their mothers bring back wounded animals, so the young can improve their killing skills. At last, the young go out with their mothers to watch and take part in the hunt.
Sea lions catch fish and let them go in front of their young. They repeat this many times until the young learn how to catch fish by themselves.
Baby orangutans(猩猩) stay with their mothers for eight years. Mothers teach their young what foods to eat and where to find them depending on the season of the year. There’s a lot to learn because orangutans eat leaves, flowers, different kinds of insects and lots of fruits.
Baby elephants don’t know how to use their trunks(象鼻子) right after birth. At first, they just swing them around and sometimes they even step on them. By watching their mothers, they gradually learn how to use their trunks to feed, bathe and cool themselves.
