Program Overview

In 1992, on a paleontological dig in the Gobi Desert, a team of
American scientists unearthed a fossil that added an interesting
perspective to the evolutionary relationship between birds and
dinosaurs. To interpret this fossil's significance, the scientists
used a systematic process called cladistics.
Cladistics is the study of the differences and similarities of
different organisms over time. The more characteristics shared
between two organisms, the more closely related they are assumed to
be. The paleontologists on the Gobi expedition found many
similarities between their dinosaur fossil and the anatomy of
present-day birds. Their findings led them to change their theories
about the evolutionary chain of dinosaurs.
