A Step in Speciation: The Analysis of Field Observations
http://www.indiana.edu/~ensiweb/lessons/step.sp.html
From DLESE Community Collection (DCC)
Comment on this resource
In this lesson about speciation and its role in evolution, different subspecies of a California salamander are placed on a grid map of California according to where samples were collected. Discussion focuses on patterns of their distribution, their likely evolutionary relationships, and probable sequence of formation from the original form (speciation).
