Comparative Classification
Below is a table comparing the classification of four animals and one plant. As you can see, the further down the page that two critters are identical, the more similar they are. For example, it's pretty obvious that humans are more like lions than ladybugs. Classification is a way of showing just how alike two organisms are. By the way, there are several places online where you can find the classification of any organism. It's pretty cool to figure out exactly how everything is related to each other.
