Genomes, Evolution, and Mathematics

The emerging field of phylogenomics integrates two major disciplines: genomics (the study of the structure and function of genes and genomes) and phylogenetics (the study of the hierarchical evolutionary relationships among organisms and their genomes). The goal of phylogenomics is to identify the common ancestry of organisms and understand their evolution through analysis of genomes. Identifying specific sequences in the genome that appears across a range of organisms points to the likelihood that they share a common evolutionary ancestor. Read the rest of this entry »
