Amborella descends from the common ancestor that lies
directly between gymnosperms and all other
angiosperms.
Below: A finer-scale look at the phylogenetic position of
Amborella. Maximum likelihood analysis of 61 concatenated
gene sequences (ca. 42,000 bp) from complete plastid
genomes. See Moore et al. (2007).
