The present study was a comparative analysis of narratives in natural history museums in order to identify and quantify the use of information on animal behavior in evolutionary context. An initial step was to gather character to prepare a data matrix where they were coded. The textual information was obtained through images (photos and videos) of the panels and other narrative elements or text files transferred by the researched institutions. The photos were assembled according to the order

... gested in the exhibition and organized in word file. The texts were transcribed and organized into word file to be analyzed. The current study contributes to a new area of research providing new set of characters (ethological, expographic and thematic) to establish standards of approach for the characters in their different forms. Phylogenetic cladistic methodology was used to establish relations between the narratives of exhibition using behavioral characters. The methodology was chosen to present relevant results for non-organismic systems. In order to become applicable, the system only needs to be subject to the Darwinian algorithm where an information system (genetic or symbolic) which shows hereditary variability (transmitted), given enough time, will be subject to the selection process that results in the adaptation of the system (narratives) to new environmental pressures (cultural). The results from the phylogenetic analysis showed low frequency of information in the approach to the subject of behavior in exhibitions in the natural history museums. On the other hand, an increase in the complexity of the resourses used in the approach to behavioral issues was observed along the branches of the tree found. This complexity is due both to the scope and theme of the exhibition about the resources applied in their executions. Thus, not surprisingly, the AMNH Darwin exhibition (with its wealth of resources) and Ethology of SDM (with its wealth of behavioral information) appear in this study as sister group within the more derived branch of the tree.
