What This Document Is
This is a laboratory introduction to the field of geometric morphometrics, a powerful set of techniques used in biological studies to quantify and analyze shape. Specifically designed for students in the Principles of Phylogenetics: Systematics course (INTEGBI 200A) at UC Berkeley, this lab guide provides a foundational understanding of the theory and practical application of these methods. It focuses on setting up the necessary software environment and initiating the process of shape analysis.
Why This Document Matters
This resource is ideal for students seeking to expand their analytical toolkit beyond traditional phylogenetic methods. It’s particularly valuable for those interested in incorporating shape-based data into their research projects, especially when investigating biological phenomena like allometry or heterochrony. If you’re looking to understand how to mathematically define and compare shapes for statistical analysis, this lab will provide a crucial starting point. Accessing the full content will equip you with the knowledge to begin applying these techniques to your own biological questions.
