Why do you think that over time there are changes in how living things are classified

In my opinion, there are two main reasons why the way we classify living things changes over time:

- The new discoveries of new species: As we started to explore more and more about the world, we also found a lot of new species like new plants or animals, even fossils can help! Let me take an example: at first, people didn't think that dinosaurs and birds are the same species, but thanks to the discovery of Archaeopteryx, we had started to think that there might be some link between these two very different species. As archeologists compare the skeleton of Archaeopteryx and the skeletons of modern bird and dinosaur, they noticed that Archaeopteryx share  some similarites with bothe species. With futher reserch, they finally disvocered that dinosaurs are actually birds ancestors, and they are pratically the same species.

- The way we look at living organism also changed over time: for example, whales were once be mistaken and classified as a fish. But when scientists have genetic information as well as more insight in to their anatomy and behaviours, scientists started to realize that whales and many fish species have a lot of differents despite the fact that they look pretty much alike. For example, pretty much all kinds of fish lay eggs, but whales (and dolphins as well) do something very different, whales give birth to calves, and the newborn animals are capable of swimming right after birth, instead of laying eggs. Base on many more traits, whales were finally classfied as mammal - the same family with gorilla, hippopotamus, etc - instead of fish.
