Pathways of lifestyles in carabid beetles, according to the taxon pulse
model identified by Erwin (1981).
Brooks (2005) stated that the taxon pulse model was more appropriate
for cladistic biogeography than the vicariance model. According to him, tax-
on pulse-driven biotic diversification differs from vicariance-driven biotic di-
versification in three ways. First, as diversification is driven by biotic expan-
sions, one expects to find general patterns associated with dispersal, not
just with vicariance. Second, episodes of biotic expansion, even those in-
volving large areas, will lead to reticulated historical relationships between
