Summary

Reliable and robust pipeline

Study and compare whole genomes

Focus on particular features

Partition into areas of interest

Visualize and summarize the data

Key evolutionary questions

Intron test case has been very insightful

Page 9: Evolutionary Comparative Genomics: Understanding the Origins of Genome Architecture

Future directions

Introns

Homology, Ontology, Synteny, Gene families

Evolutionary questions

Expansion of studies

52 genomes

Phylogenetic comparisons
