Homologous genes share a common evolutionary ancestor and can be orthologues (derived from speciation events), paralogues (derived from gene duplication events) or xenologues (derived from horizontal transfer or lineage fusion). Comparative analysis of the human genome indicates high levels of recent and ancient duplication at the level of nucleotides, genes and chromosome segments, and no unambiguous examples of recent transfer from bacteria.
