Fig. 10From: Fossil Horses, Orthogenesis, and Communicating Evolution in MuseumsDistribution of fossil horse displays in natural history museums communicating orthogenesis versus branching patterns of evolution. a Orthogenesis versus branching in the 37 individual components analyzed. b Overall pattern of evolution depicted in multi-component exhibits from 20 museums (see Table 1). Abbrev: O, orthogenetic; PO, primarily orthogenetic; M, mixed O and B; PB, primarily branching; B, branching. Numbers at the top of each bin represent sample size (N)Back to article page
