What This Document Is
These are lecture records from Principles of Phylogenetics: Ecology and Evolution (INTEGBI 200B) at the University of California, Berkeley. The material focuses on the theoretical underpinnings and practical applications of understanding evolutionary relationships, specifically as they relate to measurable characteristics of organisms. It delves into methods for reconstructing ancestral traits and modeling how these traits change over time, bridging the gap between ecological observation and evolutionary history. This resource represents a detailed record of course lectures, offering a comprehensive look at advanced phylogenetic concepts.
Why This Document Matters
This lecture record will be particularly valuable for students enrolled in or preparing for upper-division undergraduate and graduate-level courses in phylogenetics, evolutionary biology, and related fields. It’s ideal for reinforcing concepts presented in lectures, preparing for exams, or gaining a deeper understanding of the mathematical and statistical foundations of phylogenetic analysis. Researchers interested in quantitative approaches to studying evolutionary processes will also find this a useful reference. Accessing these records can significantly enhance your comprehension of complex topics and provide a solid foundation for further study.
