Fig. 4. The tree that requires the minimal number of amino acid changes at the five critical
sites under the constraint of the species phylogeny in Fig. 3. Substitutions along branches
are indicated as the ancestral amino-acid followed by its position on the complete coding
sequence and then followed by the new amino-acid. Two equally parsimonious pathways are
shown, one above branches (italic) and one below branches. A shorter tree (12 instead of 13
steps) is obtained if the marmoset-tamarin P556 allele has a recent origin and was derived
from the P562 allele, as indicated by the dashed line and arrow. From Boissinot et al. (1998)
