Scientists study the inner ear to determine the origin of mammals
Mammals can generate their own body heat and control their body temperature. This process is known as endothermic or warm-blooded. Scientists believe that may be the reason why mammals tend to dominate almost everything ecosystem . Warm-blooded mammals are more active than cold-blooded animals. They can live in different environments, from frozen poles to boiling deserts. And they breed faster. Soft tissue that will provide information about being warm or cold blooded is rare preserved in fossil . So paleontologists, or experts in the study of fossils, don’t know exactly when mammals evolved and turned into warm-blooded creatures. A group of scientists tried to answer that question in a study recently published in Natural . Ricardo Araújo is a paleontologist at the University of Lisbon. Araújo and a group of researchers proposed that the shape and size of inner ear structures called canals could be used to study body temperature. The movement of fluid through the ear canal helps
