Gene origin in human evolution. Distribution of the genes in the preimplantation pathway according to their origin in clades of the human lineage, based on the determination of the Last Common Ancestor for the ortholog clusters generated by SeedServer. The y-axis represents the number of genes and the x-axis represents the taxonomical groups in which the genes originated.
