Reevaluating cases of trait-dependent diversification in primates.

Published in: American journal of physical anthropology (2018)
These results indicate that ecological traits have had a more limited influence on primate diversification than suggested by previous studies. The false positives detected here can be linked with heterogeneity in diversification caused by sources other than the focal traits. One of these sources is the very high rate of diversification in Cercopithecoidea found in previous investigations. Another is the correlation between activity patterns and diversification. The underlying causal mechanism for the contrast in diversification dynamics between diurnal and nocturnal primates is unclear, but this correlation highlights the important role of activity pattern in shaping primate evolutionary history.
