A Step in Speciation Students compare different subspecies of a California salamander on a grid map of California to focus on patterns of their distribution, their likely evolutionary relationships, and probable sequence of formation from the ancestral salamander.
|
|
Classification and Evolution Students construct an evolutionary tree of imaginary animals (Caminalcules) to illustrate how modern classification schemes attempt to reflect evolutionary history.
|
|
Determining Age of Rocks and Fossils In this series of lessons students learn the basic principles used to determine the age of rocks and fossils by using half-life in radioactive decay and stratigraphy.
|
|
How are humans related to other primates? In this two-part laboratory lesson students analyze skull morphology and DNA sequences among primate species to answer one of the most meaningful questions in biology: How are humans related to other animals?
|
|
Inducing Evolution in Bean Beetles In this lab, students design and conduct experiments to evaluate whether evolution by natural selection (or alternatively, genetic drift) may be induced in laboratory populations.
|
|
Ornamentation in birds In this investigation students explore the connection between competition for mates and the evolution of elaborate traits in birds. Using the online database Birds of North America , students develop and test a set of hypotheses to explain the variation in sexual dimorphism among bird species.

|
Species Concepts in Birds This investigation uses multimedia such as bird songs and their associated visualizations to initiate a discussion of traits that can be used to define a species and the resulting conservation implications of that definition.

A Step in Speciation Students compare different subspecies of a California salamander on a grid map of California to focus on patterns of their distribution, their likely evolutionary relationships, and probable sequence of formation from the ancestral salamander.

|
Anolis Lizards Students "take a trip" to the Greater Antilles to figure out how the Anolis lizards on the islands might have evolved.

Classification and Evolution Students construct an evolutionary tree of imaginary animals (Caminalcules) to illustrate how modern classification schemes attempt to reflect evolutionary history.

Determining Age of Rocks and Fossils In this series of lessons students learn the basic principles used to determine the age of rocks and fossils by using half-life in radioactive decay and stratigraphy.

Investigating a Deep Sea Mystery In this lab activity, students examine authentic morphological and phylogenetic data of three fish families and then pose and test alternative hypotheses about the fishes' classification.
