Evolution and Cladogram

Cladograms are diagrams that can be used to show evolutionary relationships between different species. The diagram below is a cladogram of four plant groups. According to the diagram, which pair of groups diverged most recently?

• conifers and ferns

• conifers and mosses

• flowering plants and ferns

• flowering plants and conifers

Which of these statements is most likely true of two species that share a recent common ancestor?

• The two species have different developmental patterns.

• The two species share DNA sequences.

• The two species have similar arms and legs.

• The ancestors of each species looked very different.

Animals with segmented bodies include organisms like worms, beetles, and butterflies. Scientists study the morphological variation among these organisms to determine their evolutionary relationships. A cladogram shows the relationships among groups of animals with segmented bodies.

Use the Add Point button to place a dot on the Relationships Among Segmented Animals cladogram to show where each common ancestor diverged into a different species.
