Cladistics is a powerful modern tool for studying and understanding evolution. Cladistics attempts to do for the entire history of life what genealogy does for the history of human families: to disentangle the relationships between all living beings.ut while genealogy focuses on detailed lineages of ancestry and descent, cladograms focus on identifying the common ancestry of related groups. This cladogram represents the archosaurs, the common ancestors of crocodilians, birds, and all their descendants.
Seismograms give information about the path of seismic waves and the speed of seismic waves. The speed of seismic waves depends on the density of the material the seismic wave is traveling in. We know, for example, that the core of Earth is liquid, because S waves do not travel through the center of Earth.
