A Phylogenomic Study of Birds Reveals Their Evolutionary History
This study examined ∼32 kilobases of aligned nuclear DNA sequences from 19 independent loci for 169 species, representing all major extant groups, and recovered a robust phylogeny from a genome-wide signal supported by multiple analytical methods.
Prehistoric Extinctions of Pacific Island Birds: Biodiversity Meets Zooarchaeology

On tropical Pacific islands, a human-caused "biodiversity crisis" began thousands of years ago and has nearly run its course and the current global extinction crisis therefore has historic precedent.
Prehistoric Extinctions on Islands and Continents
Geological extinction of a continental megafauna of Holarctic mammoths, American ground sloths, and Australian diprotodonts, to name a few mammalian examples, rivals pulsing ice sheets and…

This asynchronous situation is not compatible with glacial-interglacial climate change forcing these extinctions, especially given the great elevational, latitudinal, and longitudinal variation of the sloth-bearing continental sites.
Phylogenomic evidence for multiple losses of flight in ratite birds

- 9 September 2008
A phylogenetic analyses of 20 unlinked nuclear genes reveal a genome-wide signal that unequivocally places tinamous within ratites, making ratites polyphyletic and suggesting multiple losses of flight.

Nine taxa of lizards, snakes, birds, bats, and rodents are either completely extinct or have never been recorded historically from Antigua, so rendering unreliable the data traditionally used in ecological and biogeographic studies that consider only the historically known fauna.
Prehistory and human ecology in Eastern Polynesia: Excavations at Tangatatau Rockshelter, Mangaia, Cook Islands
The Tangatatau Rockshelter (site MAN-44, Mangaia, Cook Islands) has produced one of Eastern Polynesia's most comprehensive chrono-stratigraphic sequences of artifacts, vertebrate and invertebrate…
