What is evolutionary genomics?
Genomes differ among individuals and change over time. Evolutionary genomics studies genome variability and genome changes based on evolutionary principles. Typical applications include identification of human genome variations associated with diseases and identification of pathogen virulence genes.
Genome changes are studied at two levels: (1) within-species/within-population variations (e.g., human genetic variation), and (2) between-species divergence (e.g., human-mouse comparisons).
The key for analyzing genome variations within species is "population-thinking", the idea that there is no one individual genome that is standard, normal, or disease-free.
The key for comparing genomes across species is "tree-thinking", the idea that evolution happens by diversification (like a branching tree) not by climbing a ladder. There is no such thing as "advanced" or "primitive" species. All living species have the exact same evolutionary distances/time of divergence since the origin of life.
