Additional file 5: Figure S2. of Adaptive genomic evolution of opsins reveals that early mammals flourished in nocturnal environments

Phylogenetic character mapping for the ancestral reconstructions. Ancestral reconstructions of the activity pattern and sw1-sensitivity are represented in pie charts, each slice representing the probability of each state. Ancestral inferences of the orbit convergence (degrees) and visual acuity (cycles per degree) are represented by circles that change in size and shade of grey according to the character value. The opsin trees were estimated under the assumption of the branch-specific free-ratios model using the Meredith et al. (2011) tree topology. (PDF 1239Â kb)
