Commentaries to “The Curse of a Big Head” |

jueves, abril 9, 2009, 11:58 PM Following is a transcription of one of a very interesting list of articles by G.R. Morton found in Internet, this one in http://home.entouch.net/dmd/sweat.htm in parenthesis you will find my Commentaries to “The Curse of a Big Head” Copyright 1996 G.R. Morton. This can be freely copied and distributed if unaltered and no monetary charge is made. [I include this on the web page because of the fascinating reaction it received when I posted it on a listserver. One friend thought it was bad theology but couldn't really explain why. One biologist said there were eccrine glands on camels and that they sweated a lot, yet he could not provide a book or article which supported his position. An MD provided evidence that on a per gram basis the heart uses more oxygen than any organ. The brain uses half as much oxygen as the heart on a per gram basis. If oxygen consumption is proportional to heat production, then since the heart weighs 1/5 what the brain does then the brain will produce about 2.5 times the heat of the heart. If anyone wants to provide contrary evidence to the thesis below, I am interested, but only in documented evidence.--grm] (I include it in my site because I am one of those fascinated by it.)

The first one was written by the people of Marine Census of Life of the University of Alaska, at Fairbanks.Swimming snail species February 15, 2009--Spinning a "mucus net" off its paddle-like foot-wings to trap algae and other foods, the swimming snail species Limacina helicinia is no bigger than a bean. But the discovery that it and at least 234 other species inhabit both Arctic and Antarctic waters is big news to biologists. Leer más... [ añadir comentario ] | enlace permanente | ( 3.1 / 81 ) |

Entre paréntesis encontrarán mis comentarios.El caracol nadador 15 de febrero de 2009.- La especie de caracol nadador teje una red de mucuosa proveniente de sus pies-alas para atrapar algas y otros alimentos. Este caracol nadador es del tamaño escaso de un frijol y lleva por nombre científico Limacina helicinia. Pero el descubrimiento de este animal y de cuando menos otras 234 especies que habitan en las aguas tanto en el Polo Norte como en el Polo Sur es una gran noticia para los biólogos. Leer más...
