Sea urchins belong to a group of animals that diverged from the lineage leading to humans very early. In that capacity their genomes reflect basic qualities of this lineage and inform to a deep reach of time the evolutionary changes leading to in the human genome. Surprisingly, the invention of new genes in this evolutionary path is subordinate to the diverse changes in the abundance of genes in existing families.
