Dear MEL School’s
Topic Readers,
Dinosaurs 'neither
warm nor cold blooded'
Highly metabolized
creatures such as mammals and birds need to eat a lot and often to move faster and
think more intelligently. They also burn the food to keep their body and blood temperatures
higher and more stable than those that don’t metabolize as much as they do such
as reptiles and fish.
Which category is
more economical or ecologically advantageous thus sustainable? Are there any creatures
now or in the past that don’t fit to either high or low metabolic categories?
Some researchers
seem to have an answer. Dinosaurs. They analyzed fossil bones of dinos and
found that their growth speed fits between warm and cold blooded categories.
Enjoy reading and
learning about metabolic system of beings.
