On Nov. 11, 2020, An international team of researchers with an effort called the Zoonomia Project announced that they had analyzed and compared the whole genomes of more than 80 percent of all mammalian families, spanning almost 110 million years of evolution. The genomic dataset, published in Nature, included genomes from more than 120 species that were not previously sequenced, and captures mammalian diversity at an unprecedented scale.

The Zoonomia Project, formerly called the 200 Mammals Project, builds on a previous project, the 29 Mammals Project, which began sequencing mammalian genomes in 2006.
