Phylogenetic Systematics: Developing an Hypothesis of Amniote Relationships
Biodiversity studies begin with patterns of evolutionary diversification, made possible by phylogenetic systematics. Phylogenetics clusters species into groups depicting their common ancestry based on shared derived characters unique to that group. It is quantifiable, reproducible, and scientifically testable, and has three assumptions: evolution has occurred, there is a single phylogeny of life resulting from evolutionary diversification, and characteristics are passed from generation to genera

Using composite materials to replace bone
In this podcast, Professor Chris Rudd, Dean of the faculty of Engineering at the University of Nottingham, describes his work with composite materials in the car industry and how it can be applied to the field of medicine. Traditionally, patients who have lost bone in an accident or have had bone removed due to cancer have had to endure two very long and very painful operations. One operation to attach steel plates to the bone, and a second operation once the bone has healed, to remove them. F

What is a Profile?
Using TIG profiles as an entry point, this activity explores a broader theme of "profiling" to enable students to examine how they present themselves, as well as cultural perceptions and biases within themselves, their peers, and their community. Students will read TIG profiles and Member Stories, with the objective of better understanding others' perspectives to critically reflect and write about their own identity.

DNA Sequencing Used to Illustrate Mutations and Evolution
This workshop, which is half wet lab and half Internet lab, uses DNA sequences to examine the relatedness of different species. DNA from several insect and/or fish species are compared. This chapter includes instructions for extracting DNA from gels and making PCR products. We prepare PCR products to send to a computerized automated sequencing facility. (No radioisotopes are used in this sequencing!) We recover sequence from the facility over the Web as four-color graphics on a computer screen a

DNA Microarrays: Background, Interactive Databases, and Hands-on Data Analysis
DNA microarrays are influencing many areas of biology. DNA microarrays allow investigators to measure simultaneously the activity of every gene in a genome. This paper provides the reader with background information, a set of interactive questions, and most importantly, free software (MAGIC Tool) for use in the undergraduate curriculum. MAGIC Tool (www.bio.davidson.edu/MAGIC) resources allow the user to understand how DNA microarray data are analyzed by providing raw data, instructions, mathemat
