What This Document Is
This document explores the fascinating intersection of evolutionary biology and developmental processes – often referred to as “evo-devo.” It delves into how changes in development contribute to the evolution of biological forms, examining the complex interplay between genes, environment, and phenotype. The material is geared towards an upper-level undergraduate course in phylogenetics, ecology, and evolution, offering a detailed look at the mechanisms driving morphological change over time.
Why This Document Matters
Students enrolled in advanced evolutionary biology, developmental biology, or phylogenetics courses will find this resource particularly valuable. It’s ideal for those seeking a deeper understanding of how developmental processes shape evolutionary trajectories and how to interpret evolutionary relationships in light of developmental data. This material will be most helpful when studying the genetic and developmental basis of phenotypic diversity, or when preparing to analyze character evolution within a phylogenetic context.
Topics Covered
* The relationship between ontogeny (development of an individual) and phylogeny (evolutionary history)
* Evolutionary changes in the timing of developmental events (heterochrony)
* Evolutionary changes in the location of developmental events (heterotopy)
* Differences in developmental strategies between plants and animals
* The role of gene expression and genetics in developmental evolution
* The evolution of gene families, with a specific focus on Hox genes
* Methods for studying the genetic basis of developmental change
What This Document Provides
* A comparative framework for understanding developmental evolution.
* Terminology related to heterochronic processes and their impact on evolutionary change.
* An overview of different genetic approaches to studying development, including forward and reverse genetics.
* Discussion of the unique developmental characteristics of plants compared to animals.
* Exploration of the role of gene duplication in the evolution of developmental systems.
