"In the past two decades, studies of anatomy, behavior, and, most recently,
DNA sequences have clarified the phylogeny of the ants at the subfamily and
generic levels. In addition, a rich new harvest of Cretaceous and Paleogene
fossils has helped to date the major evolutionary radiations. We collate
information and then add data from the natural history of the modern fauna
sketch a history of major ecological adaptations at the subfamily level. The
key events appear to have been, first, a mid-Cretaceous initial radiation in
forest ground litter and soil coincident with the rise of the angiosperms
(flowering plants), then a Paleogene advance to ecological dominance in
concert with that of the angiosperms in tropical forests, and, finally, an
expansion of some of the lineages, aided by changes in diet away from
dependence on predation, upward into the canopy, and outward into more xeric
This paper has been around in presses already, so I am noting it only that it
is now officially in print, so the pagination and issue numbers are final:
(Note the very long URL). The DOI number is DOI: 10.1007/s00114-005-0623-3,
and the official online publication date for this is April 16, 2005, but print
publication is dated for May, 2005.

(Carnivora, Herpestidae) from Africa (late Miocene of Chad).

"We report on the earliest modern mongooses of Africa, from the late Miocene
(ca. 7 Ma) of the hominid locality TM 266, Toros-Menalla, Chad. The material
is based on fragmentary dentitions of three individuals. The main diagnostic
feature of the Chadian species is the great development of the shear in the
carnassials, which distinguishes the Chadian specimens from all extant
herpestids except *Herpestes* and *Galerella*. In comparison with most
extinct and extant *Herpestes*, the species from Toros-Menalla differs by a
markedly smaller size and, depending on the species, relatively more
elongated carnassials, more transversely elongated M1 and more reduced p4.
the basis of a great morphological similarity and the absence of significant
differences, we assign our material to *Galerella sanguinea*; the Chadian
finding therefore represents the earliest appearance of an extant species of
Herpestidae. This record ties the first appearance of the genus to a minimum
age of ca. 7 Ma, which is consistent with the estimated divergence date of
11.4 Ma known from the literature for the species of *Galerella*.

Little steps are often the hardest to take. We are too used to making leaps
in the face of adversity, that a simple skip is so hard to do. We should all
learn to walk soft, walk small, see the world around us rather than zoom by it.
