![An unrooted maximum-likelihood phylogenetic tree of the catalytic subunit (HydA) of [FeFe] hydrogenases and the hybrid hydrogenases. The tree was constructed based on 3,677 amino acid sequences using the LG + C20 + R + F model. The numbers at the branches indicate the aLRT (approximate likelihood ratio test) and ultrafast bootstrap (within bracket) support values, each with 1,000 replicates. The scale bar corresponds to the expected number of substitutions per site. Colored circles at the tip indicate sequences from eukaryotes and major archaeal groups. All other sequences are from bacteria. -- Cell](https://i0.wp.com/astrobiology.com/wp-content/uploads/2024/06/How-Archaea-The-Third.png?resize=1200%2C720&ssl=1)
