Cladogram

A scientific diagram showing the evolutionary relationships between different living things. If you start at the bottom of a cladogram and work your way to an animal at the top, you can trace its major adaptations over time.

Animals are closely related if their branches meet up close to the top. The closer to the bottom their branches meet up, the less closely related they are.

How is this cladogram different from the cladogram in our book?
