What does a cladogram show us? • A cladogram shows evolutionary relationships between groups of living things. It is like a family tree for species.

How do you read a cladogram? • The closer two species are on the cladogram, the more closely they are related. This means they evolved apart more recently. • Sometimes a cladogram will list the characteristics that make two groups or organisms different. Everything past this point has four walking legs!

How do you make a cladogram? Let’s make a cladogram that includes slugs, catfish, frogs, tigers, and humans. A. Make a table of some adaptations that the organisms share, and some that are unique. For example: Cells Slug Catfish Frog Tiger Human Backbone Legs Hair Thumbs

How do you make a cladogram? B. Draw your cladogram. It is assumed that organisms with more of the traits evolved later, so they go at the top or on the right. Less evolved organisms go at the bottom or left side of the cladogram.
