Descripción
Octodontoidea is the most species-rich clade
among hystricomorph rodents. Based on a combined parsimony
analysis of morphological and molecular data of extinct
and extant species, we analyze the history of South
American octodontoids and propose ages of divergence older
than interpreted so far. Early Abrocomidae are recognized for
the first time, and a new definition of the family is provided.
Traditionally accepted fossil-based times of origin for the
southern clades are reinterpreted as later stages of differentiation
markedly uncoupled from the origin, differentiation implying
specializations for open environments as shown in a
morphospace of skull variation. Origin of crown groups is also
strongly uncoupled from origin of clades as a consequence of
extinction of deep lineages. In the resulting diversity pattern of
modern southern clades of octodontoids, the combination of
greater disparity, less content of evolutionary history, and lower
taxonomic diversity, compared to their northern counterparts,
appears at first counterintuitive.We propose that primary
components of diversity derived from evolutionary transformation
or anagenesis, on the one hand, and from cladogenesis
and extinction, on the other, should not be considered
associated, or at least not necessarily. Certain patterns of
relationships between these distinct components could be
driven by environmental dynamics. Like environments,
octodontoid diversity would have been more stable in northern
South America, whereas in the south, both strong adaptive
change and extinction would have been triggered by emerging
derived environments.
