Genetic Analysis of Lice Supports Direct Contact between Modern and Archaic Humans
Parasites can be used as unique markers to investigate host evolutionary history, independent of host data. Here we show that modern human head lice, Pediculus humanus, are composed of two ancientExpand

The population genetics of host specificity: genetic differentiation in dove lice (Insecta: Phthiraptera)
Some species of parasites occur on a wide range of hosts while others are restricted to one or a few host species. The host specificity of a parasite species is determined, in part, by its ability toExpand

When do parasites fail to speciate in response to host speciation?
Cospeciation generally increases the similarity between host and parasite phylogenies. Incongruence between host and parasite phylogenies has previously been explained in terms of host switching,Expand

Comparative ecology of Neotropical bird lice (Insecta: Phthiraptera)
Data are presented comprising the first quantitative survey of lice from Neotropical birds. The data were collected in the Andean foothills of south-eastern Peru using a novel scheme for quantitativeExpand

The influence of parasites on host sexual selection.
In 1982 Hamilton and Zuk(1) proposed a provocative solution for the unexplained fact that the males of many species exhibit 'showy' traits such as brightly coloured plumage or vigorous courtshipExpand

How Birds Combat Ectoparasites
Birds are plagued by an impressive diversity of ectoparasites, ranging from feather-feeding lice, to feather- degrading bacteria. Many of these ectoparasites have severe negative effects on hostExpand

Ecology of congruence: past meets present.
Phylogenetic congruence is governed by various macroevolutionary events, including cospeciation, host switching, sorting, duplication, and failure to speciate. The relative frequency of these eventsExpand
