One other reasonably northern query, however why don’t geese’ toes – with their skinny webs – freeze to the ice? Clearly, like the whole lot else nowadays: due to world warming!
The actual reply lies within the design of the blood circulation system within the legs of geese (and lots of different creatures). The arteries and veins are in shut proximity to one another. Geese do get chilly toes, however not ice-cold. There’s a counter-current warmth change between the nice and cozy arterial blood flowing to the foot and chilly venous blood getting back from the foot. This technique maintains as a lot warmth within the physique core of the duck as attainable with out letting the foot freeze. People, not being birds, are imperfect. As primates we would not have these chilly climate variations, nor did our toes contact the bottom till Lucy dropped out of her tree. We stand on the ice lengthy sufficient and our toes freeze to the ice, our blood continues being chilled down and eventually our core temperature drops under the mandatory minimal. And that’s not the one factor that may drop down…
In fact, this was a really boring query with a reasonably grotesque ending. There are numerous extra enjoyable information about waterfowl that don’t finish with frozen people.
