The Darwin Tree of Life Project
- Genomic sequence data is available for less than 1% of Earth’s species.
- The Darwin Tree of Life project, a collaborative project including the Wellcome Sanger Institute, aims to produce high-quality reference genomes for the estimated 70,000 eukaryotic species in Britain and Ireland.
- Many other international projects are aiming to sequencing the genomic diversity of other countries and regions across the world.
