Evogram

An important systematic account with illustrations of Shaw's tephigram, the emagram, Refsdal's aerogram, Schinze's thetagram, Robizach's diagram, evogram, and Rossby's diagram.

Teachers can facilitate such learning by incorporating cladistics and tree-thinking into the curriculum and using evograms to focus on important evolutionary transitions.

Providing the basics for tree reading suggests that the use of evograms (evolutionary diagrams integrating different lines of evidence) reflects more accurately and integratively how scientists know what they know about the major changes in evolution.

Remember, a cladogram or evogram is a branching, treelike diagram in which the endpoints of the branches represent specific species of organisms.
