Beautiful plumage: Feather color and sex start the species revolution
August 06, 2009Faculty of 1000, the leading scientific evaluation service, has highlighted research providing evidence for the evolution of a new species.
Birds use plumage colour to recognize and select potential mates. A mutation of a single DNA base can lead to a striking colour change, as demonstrated by two closely related flycatcher populations in the Solomon Islands. According to a report in the American Naturalist -- selected and reviewed by Faculty of 1000 member Rebecca Kilner (University of Cambridge) along with Associate Rose Thorogood -- this tiny genetic difference can potentially lead to the evolution of new species.
Two Monarcha castaneiventris sub-species have the same body shape, but different colored bellies and distinct songs. Birds from these sub-species could mate, but these differences stop them recognizing each other as potential sexual partners. This is evidence of incipient speciation: the beginning of the evolution of new species. Other flycatchers in the Solomon Islands also vary their plumage colour, but the genetic basis is not always as clear as this single mutation.
Dr Kilner highlighted this intriguing paper because it shows how a single gene can cause colour change in birds, affecting the selection of potential sexual partners. This leads to reproductive isolation and eventually speciation, but, she says, "in ways that are more complex than previously appreciated".

New Species Current Events and New Species News RSSScientists Unravel Evolution of Highly Toxic Box Jellyfish
With thousands of stinging cells that can emit deadly venom from tentacles that can reach ten feet in length, the 50 or so species of box jellyfish have long been of interest to scientists and to the public. Yet little has been known about the evolution of this early branch in the animal tree of life.
Funny, you don't look related
When Charles Darwin visited the Falkland Islands during the voyage of the Beagle in 1835, he saw a wolf-like species, wrote about it in his diaries and correctly commented that it was being hunted in such large numbers that it would soon become extinct.
The bizarre lives of bone-eating worms
The females of the recently discovered Osedax marine worms feast on submerged bones via a complex relationship with symbiotic bacteria, and they are turning out to be far more diverse and widespread than scientists expected.
DNA barcodes: Creative new uses span health, fraud, smuggling, history, more
The scientific ability to quickly and accurately identify species through DNA "barcoding" is being embraced and applied by a growing legion of global authorities - from medical and agricultural researchers to police and customs authorities to palaeontologists and others.
New dinosaur species from Montana
A husband and wife team of American paleontologists has discovered a new species of dinosaur that lived 112 million years ago during the early Cretaceous of central Montana.
Inconspicuous leaf beetles reveal environment's role in formation of new species
Unnoticed by the nearby residents of St. Johnsbury, Vermont, tiny leaf beetles that flit among the maple and willow trees in the area have just provided some of the clearest evidence yet that environmental factors play a major role in the formation of new species.
New analyses of dinosaur growth may wipe out one-third of species
Paleontologists from the University of California, Berkeley, and the Museum of the Rockies have wiped out two species of dome-headed dinosaur, one of them named three years ago - with great fanfare - after Hogwarts, the school attended by Harry Potter.
Scientists discover largest orb-weaving spider
Researchers from the United States and Slovenia have discovered a new, giant Nephila species (golden orb weaver spider) from Africa and Madagascar and have published their findings in the Oct. 21 issue of the journal PLoS ONE.
Chinese and American paleontologists discover a new Mesozoic mammal
An international team of paleontologists has discovered a new species of mammal that lived 123 million years ago in what is now the Liaoning Province in northeastern China.
Tropical regions to be hardest hit by fisheries shifts caused by climate change: UBC research
Major shifts in fisheries distribution due to climate change will affect food security in tropical regions most adversely, according to a study led by the Sea Around Us Project at The University of British Columbia.

Bots: The Origin of a New Species by Andrew Leonard (Author) Bots is the story of cyberspace's first indigenous species. Strings of code, bots are a software version of a mechanical robot. Originally meant to do our bidding, when unleashed by computer hackers bots can disable computing systems and engage in personal attacks, and are capable of causing nuisance and chaos all over the Internet. Bots have great potential for either organizing our lives or sabotaging them. In telling the tale of the development of software robots, Andrew Leonard constructs a playful, fascinating, anecdote-rich history of the Internet, tracking it from the free-form ASCII-text playground of chipheads, researchers, and scientists to the sprawling, advertising-laden, cultural entity it has become. In an expert and entertaining book, Leonard makes a sophisticated... |
