12 lut 2008 · For example, the tree in Fig. 11 shows only a single fish, a frog, a lizard, a bird, a cat, and a human, but in actuality, these six terminal nodes together represent more than 50,000 species of living vertebrates and an untold number of ancestors. The important point is that any given node, whether internal or at the tips, represents a diverse ...
Taxonomy of ray-finned fishes (Actinopterygii) based on a comprehensive fish phylogeny, the Phylogenetic Fish Classification.
The shape of the bony fish tree of life is currently better resolved for the early-branching lineages than for the more apical acanthomorph groups, in particular the percomorphs, a large and diverse group of spiny-finned fishes with uncertain affinities that came to be known as “bush at the top”44. Few basal branching events

Rhacophorids are small to large frogs (15 - 120 mm snout-vent length) bearing several arboreal adaptations, including cartilaginous intercalary elements between the terminal and penultimate phalanges, and toe discs. They have flattened bodies, with broad, flat skulls.
