Brood parasitic black-headed ducks caught in their host's interspecific arms race

Courtesy of CDCUS researchers are looking to otherwise unwanted guests to piece together humans' evolutionary past: lice. They suggest that modern Homo sapiens may have had direct physical contact with Homo erectus in Asia before crossing over to the New World.Florida Museum of Natural History's David Reed and colleagues present evidence that the New World lineage of head and body lice coevolved with H. erectus, but switched hosts to H. sapiens around 25,000 years ago.1 The effective isolation o

Two studies appear to confirm DNA barcoding as a powerful taxonomic tool. Paul Hebert and colleagues at the University of Guelph, Ontario, analyzed the single gene for cytochrome c oxidase I to distinguish 260 known North American bird species. The so-called DNA barcodes identified four new cryptic species as well.1The group also used the technique to demonstrate that the neotropical skipper butterfly, Astraptes fulgerator, comprises at least 10 species.2 Felix Sperling of the University of Albe
