Figure 1. Venn diagram of orthologs genes for 8 species.
Figure 2. Maximum-likelihood tree constructed based on 1,233
one to one single copy orthologs genes of 8 species. Colored branches
indicate bat species within the macrotis group. Orange and blue
lines represent species with low and normal echolocation frequency
relative to body size respectively.
Figure 3. dN/dS values for each species calculated from
sequence of concatenated homologous genes.
Figure 4. Venn diagram of positively selected genes selected
from branches of species within the macrotis group.
Figure 5. A part of amino acid sequence alignments of the genes
related to hearing. (a)-(f) In these sequences, the first and the last
positive selected sites were labeled, and the posterior probability of
corresponding sites were represented. The species used to test the amino
acid change were indicated by a line. (g) The positive selected sites
were labeled and the posterior probability of corresponding sites were
represented. The same amino acid change occurred in R. osgoodiand R. pusillus were indicated by the line.
