New investigation of tissues and signaling pathways in finches' beaks reveals surprising flexibility in the birds' evolutionary toolkit It has long been known that diversity of form and function in birds' specialized beaks is abundant. Charles Darwin famously studied the finches on the Galapagos Islands, tying the morphology (shape) of various species' beaks to the types of seeds they ate. In 2010, a team of Harvard biologists and applied mathematicians showed that Darwin's finches all...

Lee Rannals for redOrbit.com — Your Universe Online The genome of Galapagos finches have been sequenced for the first time in an international collaboration between the Genome 10K project and BGI. The finch, which was first described by Charles Darwin, is the first of the BGI-Genome 10K collaboration to be made available through the UCSC Genome Browser. "The scientific advancement," Erich Jarvis said in a press release, "is that it will allow us to investigate the genomes of a...

Scaling and shear link morphology, genotype and developmental genetics From how massive humpbacks glide through the sea with ease to the efficient way fungal spores fly, applied mathematicians at Harvard have excavated the equations behind a variety of complex phenomena. The latest numerical feat by Otger Campàs and Michael Brenner, working closely with a team of Harvard evolutionary biologists led by Arhat Abzhanov, zeroes in on perhaps the most famous icon of evolution:...

Darwin's finches develop antibodies to flies, pox virus Unlike Hawaii and other island groups, no native bird has gone extinct in the Galapagos Islands, although some are in danger. But University of Utah biologists found that finches "“ the birds Darwin studied "“ develop antibodies against two parasites that moved to the Galapagos, suggesting the birds can fight the alien invaders. With the discovery that the medium ground finches produce antibodies aimed specifically at the...

Scientists at Scripps Research make molecules that evolve and compete, mimicking behavior of Darwin's finches As described in an article published this week in an advance, online edition of the journal Proceedings of the National Academy of Sciences (PNAS), the work demonstrates some of the classic principles of evolution. For instance, research shows that when different species directly compete for the same finite resource, only the fittest will survive. The work also demonstrates how, when...

WASHINGTON -- Finches on the Galapagos Islands that inspired Charles Darwin to develop the concept of evolution are now helping confirm it - by evolving. A medium sized species of Darwin's finch has evolved a smaller beak to take advantage of different seeds just two decades after the arrival of a larger rival for its original food source. The altered beak size shows that species competing for food can undergo evolutionary change, said Peter Grant of Princeton University, lead author of the...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
