Classifying the Plants
Scientists use a type of diagram called a cladogram to help describe evolutionary relationships among organisms. A cladogram looks somewhat like a tree, with each branch marking the evolution of a new feature. These features, called derived characters, help untangle the pattern of relationships between different groups of organisms.
Use the data in the table below to fill in the cladogram below. A "0" means the trait is not present in the organism, and a 1 means that it is present. In addition, place the characteristics in the chart in the correct location on the cladogram. (12 points)
