Summary:
Using CT (Computed Tomography) scans of vertebrate forelimbs, both as 3D models and as shapefiles, to enhance and illustrate the concepts of homologous structures, and the evolution of anatomical structures as a function of their use.
Description
This lesson plan uses the products of the oVERT project, at the University of Florida, in order to make the Evidence of Evolution section of the Middle School Scope and Sequence both more hands on, and more attractive to students of the technological age. Specifically, it uses the CT (Computed Tomography) scans of vertebrate forelimbs, both as 3D models and as shapefiles, to enhance and illustrate the concepts of homologous structures, and the evolution of anatomical structures as a function of their use (i.e. locomotion, grasping, and burrowing).
