Canine vision influenced by skull size and shape
idiot
"Handsome Jack Morrison" wrote in message ... Interesting new paper on canine vision... http://tinyurl.com/3feo6 I haven't digested it all yet(or what it might mean for handling, training, etc. certain breeds), but I (and Bark Magazine) think it boils down to: 1. long-nosed dogs have a line of high-density vision cells running across the retina(unlike humans), i.e., more peripheral vision, thus an increased ability to detect moving game at a distance 2. short-nosed or flat-faced dogs have these same vision cells arranged in a centralized spot on the retina(much like a humans do) 3. short-nosed and flat-faced dogs have nearly three times the density of vision cells as long-nosed dogs, suggesting that they might be able to see in much higher definition than long-nosed dogs This theory should be rather easy to test, but I think I'll leave that to the "experts." -- Handsome Jack Morrison *gently remove the detonator to reply via e-mail Hidden Numbers: What the NYTimes won't tell you about its own poll! http://www.nationalreview.com/commen...0403190840.asp Professor Bainbridge Daniel Drezner http://www.professorbainbridge.com/ http://www.danieldrezner.com/blog/ Glenn Reynolds - InstaPundit Steven Den Beste http://www.instapundit.com/ http://www.denbeste.nu/ SpinSanity Dhimmi Watch http://www.spinsanity.org/ http://www.jihadwatch.org/dhimmiwatch/ Don Luskin Rightwing News http://www.poorandstupid.com/chronicle.asp http://www.rightwingnews.com/ Allah is in the house!
