 | A name by any other tree
Phylogenetics has affected almost every area of biology - even the most basic one: how we classify organisms. Find out how phylogenetic classification works and what its advantages are.

 | Adventures at Dry Creek
In this interactive web-based module students conduct a simulated field study at a fossil dig in Montana.
|
|
 | Artificially Selecting Dogs
Students learn how artificial selection can be used to develop new dog breeds with characteristics that make the dogs capable of performing a desirable task.
|
|
 | Battle of the Beaks
Students learn about adaptive advantage, based on beak function, by simulating birds competing for various foods.
|
|
 | Big Beans, Little Beans
Students measure and note the variation in the lengths of lima beans. Students then compare the growth rate of different sized beans.
|
|
 | Climate Analysis Using Planktonic Foraminifera
Students manipulate, plot, and interpret data on the occurence of a particular species of foraminifera in the fossil record in order to infer changes in climate during the last 160,000 years.
|
|
 | Clipbirds
Students learn about variation, reproductive isolation, natural selection, and adaptation through this version of the bird beak activity.
|
|
 | Comic strip: Survival of the sneakiest
This comic follows the efforts of a male cricket as he tries to attract a mate, and in the process, debunks common myths about what it means to be evolutionarily "fit."

|
 | Darwin's "extreme" imperfection?
Darwin used the words "extreme imperfection" to describe the gappy nature of the fossil record - but is this really such a problem? This article delves into the topic of transitional fossils and explores what we have learned about them since Darwin's time.

 | Dino-Data
Students are presented with a set of data about dinosaurs and are asked to make hypotheses about what the data can tell us.
|
|
 | Discovering the great tree of life
This short video introduces basic concepts in phylogenetics and provides a model to help understand lineage-splitting.
This resource is available from the Peabody Museum of Natural History

|
 | Dogs and Turnips
In this lesson students attempt to assemble a meaningful sentence by successively turning over cards with words on them. The point is made that we change our ideas of what a story may be as we gather more information.
|
|
 | Getting into the Fossil Record
In this interactive module students are introduced to fossils and the fossilization process by examining how fossils are formed and the factors that promote or prevent fossilization.
|
|
 | Great Fossil Find
Students are taken on an imaginary fossil hunt and hypothesize as to the identity of the creature they discover. Students revise their hypotheses as new evidence is "found."
|
|
 | How Much is a Billion
In this activity, students get a sense of how big a billion really is, which is necessary in order to understand deep time.
|
|
 | Interpreting the Tracks
Students discover the relationships among foot length, leg length, stride length and speed in bipedal animals that provide clues about dinosaur speed.
|
|
 | Lines of evidence: The science of evolution
The theory of evolution is broadly accepted by scientists — and for good reason! Learn about the diverse and numerous lines of evidence that support the theory of evolution.
|
|
 | Nature of science
Understanding how science works allows one to easily distinguish science from non-science. Thus, to understand biological evolution, or any other science, it is essential to begin with the nature of science.
|
|
 | Sequencing Time
Students assign relative and numerical times to events in their lives to understand how scientists developed the Geologic Time Scale.
|
|
 | The Making of the Fittest: The Birth and Death of Genes
This 13-minute film describes how scientists have pieced together the evolutionary history of the Antarctic icefish by studying its genome – an excellent case study for genetic evolution as both the gain and loss of genes have led to key adaptations.
|
|
 | Understanding Geologic Time
A web-based module in which students gain a basic understanding of geologic time, the evidence for events in Earth's history, relative and absolute dating techniques, and the significance of the Geologic Time Scale.
|
|
 | What Came First?
Students sequence actual events in the history of life on Earth and place them on a large timeline.
|
|
 | What did T. Rex Taste Like?
In this web-based module students are introduced to cladistics, which organizes living things by common ancestry and evolutionary relationships.
|
|
 | Who's on First? Relative Dating
Students sequence familiar items and then do a similar sequencing activity using fossil pictures to learn how paleontologists use fossils to give relative dates to rock strata.
|
|
 | Xenosmilus
Students play the roles of paleontologists on a dig. They “unearth” a few fossils at a time and attempt to reconstruct the animal the fossils represent.
