Evolution of Temperature Regulation and of Constancy of Function (Homeokinesis) at Different Tempergeneral. Subsequently, some of the ways in which the general adaptations to temperature may apply to Agnatha and Chondrichthyes will be considered. All organisms, both prokaryotes and eukaryotes, have mechanisms for lessening the kinetic effects of cooling and warming.

On Urea Formation in Primitive Fishes,y man. A century passed before Krebs and Henseleit (1932) demonstrated the biosynthesis of urea by mammalian liver through a process they termed the “ornithine cycle”. It is fitting and historically instructive to note that between these two scientific achievements Salkowski (1877–78) provided the l

Some Aspects of Hormonal Regulation of Metabolism in Agnathans,od sugar, appeared in 1942. For about twenty years this pioneer effort was not followed by additional research on the metabolic effects of the hormones in cyclostomes. In the early sixties, almost simultaneously and independently of each other, zoologists from Austria, the USSR, Sweden and Great Bri

Hagfish Insulin: Evolution of Insulin,arbohydrates and amino acids, stimulates biosynthesis of lipids and proteins. Thus, insulin has major effects upon nutrition, both at the cellular level and at the level of integrating the anabolic needs of an organism. The evolution of the insulin molecule and its receptors-effectors is an interest
