Abstract The physiological demands of flight exert strong selection pressure on avian morphology and so it is to be expected that the evolutionary loss of flight capacity would involve profound changes in traits. Here, we investigate morphological co

Little Spotted Kiwi (LSK; Apteryx owenii) have the lowest genetic diversity of five currently recognised kiwi species apparently due to a bottleneck when at most five individuals were translocated to Kapiti Island in 1912. Ancient DNA analyses show t

Recent evolution of extreme sexual dimorphism in the huia (Heteralocha acutirostris; Callaeidae)

The New Zealand wattlebirds (Callaeidae) are an endemic New Zealand passerine family whose species show extreme variation in bill morphology. In particular, the extinct huia (Heteralocha acutirostris) has attracted considerable attention because it e

Publikováno v: PLoS Genetics, Vol 4, Iss 10, p e1000209 (2008)

Precise estimations of molecular rates are fundamental to our understanding of the processes of evolution. In principle, mutation and evolutionary rates for neutral regions of the same species are expected to be equal. However, a number of recent stu

Xenarthra (armadillos, sloths, and anteaters) constitutes one of the four major clades of placental mammals. Despite their phylogenetic distinctiveness in mammals, a reference phylogeny is still lacking for the 31 described species. Here we used Illu
