Names are extremely important in our lives. Giving something a name allows us to collect knowledge about that something. The something becomes part of our world. Something to interact with now and later. In biology names are just as important. We wouldn't get far if we had to talk about the smallest, flappy thing that swims around in the big, blue wobbly thing. Or adorable, fluffy thing often found in urban structures with big-brained bipeds. Calling then Little Penguins or kittens respectively saves a lot of time and is so much more precise. In biology we are most interested in species names, and because humans are so good at giving names to living things, science has agreed on a system that gives each species a scientific name, the genus and species names. Little penguins are also known as blue penguins and fairy penguins but to science the species is known as Eudyptula minor. And it is known by this name everywhere regardless of what the locals call it. This means that scientists know exactly what species is being talked about when we read about a piece of biological work.
