Brett Smith for redOrbit.com - Your Universe Online While birds’ three fingers appear analogous to our own thumb, index and middle fingers, embryonic evidence has shown that the “pinky” side of a bird’s claw develops first, which some theories have said is evidence of the three bird fingers being an index, middle and ring finger. According to a new study published in the Journal of Experimental Zoology, as dinosaurs evolved into birds, they actually lost their pinky and thumb,...

Evolution adds and subtracts, and nowhere is this math more evident than in vertebrates, which are programmed to have five digits on each limb. But many species do not. Snakes, of course, have no digits, and birds have three. Yale scientists now have a good handle on how these developmental changes are orchestrated in the embryo, but there is still one outstanding debate on birds: Which digits are they: a thumb with index and middle fingers, or the index, middle and ring fingers? In...

Women find men whose ring fingers are longer than their index fingers more attractive, according to findings in a study published by the British Royal Society's journal Biological Sciences. Previous studies which were conducted under the banner of evolutionary psychology, suggests that the drivers of human behavior are found in "nature" rather than "nurture," reports AFP. Led by Camille Ferdenzi of the University of Geneva, the new study was designed to find out if women are drawn to the...

Dogs and 2-year-olds limited in ability to understand unfamiliar pointing Dogs and small children who share similar social environments appear to understand human gestures in comparable ways, according to Gabriella Lakatos from Eötvös University in Budapest, Hungary, and her team. Looking at how dogs and young children respond to adult pointing actions, Lakatos shows that 3-year-olds rely on the direction of the index finger to locate a hidden object, whereas 2-year-olds and dogs...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
