What makes a bird a bird or a mammal a mammal? Grouping creatures together can show what links different creatures together.

Scientists group animals and plants together to show how related they are to one another. However, appearance alone can’t always be used to classify a living thing – DNA sequencing can also be used to identify species and work out how closely they are related to others.

Through this sorting activity you will use a simple classification key to sort and identify animals (vertebrates and invertebrates) based on their features.
