Grooming relationships reinforce social structures and cement social bonds. The Laetoli site, in Tanzania, is most famous for: Oppel's zones are named after a particular distinctive fossil species, called an index fossil.

According to Charles Darwin, natural selection operates at the level of: Although absolute ages are not necessarily critical for well correlations, they are vital in studies that rely on determinations of geologic rates.

The principle of intrusive relationships concerns crosscutting intrusions.
