Does it really matter if we know how old animals are? To many scientists, it does.
When studying animal populations, it is very important for scientists to know how many animals there are and how old they are. This information can help scientists learn which animals are thriving (兴旺) and which ones need more care and help. Scientists usually use the following ways to tell animals’ age.
For many animals, their teeth can help scientists know their age. In some animals, some teeth don’t come in until a certain age. Take cows for example. Like humans, cows have two sets of teeth, milk teeth and permanent teeth (恒牙). They normally get their first pair of permanent teeth when they’re two years old. Then they have the next pair at age three, the third pair at age four...
Hair and skin (皮肤) can also provide information about age. Some animals will possibly get bad skin and gray hair as they get older. If you have an older dog, you may have noticed that its nose and mouth get grayer as it gets older.
Scientists are continuing to discover new and more ways of telling the age of animals. Recently, scientists learned that they could tell the age of humpback whales (座头鲸) by examining their DNA. That’s really good news!

Some animals can easily find their way home after a long journey. How do they make it? Scientific research shows that they are born with certain unusual abilities for direction.
A certain kind of ants, for example, can count their steps to avoid getting lost. They can go as far as 110 meters and bring food home. These ants live in the open desert, so they have nothing to guide them along the way. It’s like someone walking six kilometers through a dark forest.
Some fish have an unbelievable sense of smell. They can smell even a single drop of their home water in a large sea area. Some sea birds have a similar ability. They are able to make a smell map of their flying area.
Some animals can sense the earth’s magnetic field (磁场), while humans can’t. This magnetic field guides a certain kind of fish when they swim a long way to a place and then back, How can this kind of fish do that? It is still a mystery. Scientists have no good answers yet.
However, animals with such unusual abilities still have difficulty dealing with environmental changes caused by human activities.
