Endotherm, so-called warm-blooded animals; that is, those that maintain a constant body temperature independent of the environment. The endotherms primarily include the birds and mammals; however, some fish are also endothermic. If heat loss exceeds heat generation, metabolism increases to make up.

The evolution of ‘warm bloodedness’ allowed mammals to live in a more diverse range of habitats, but working out when this occurred has been difficult. To try to pin down a date, researchers have studied the fossilized remains of ancient mammals’ inner ears, which suggest that this key evolutionary leap appeared around 230 million years ago.

Hydrogen dependent CO2 reductase is an enzyme that can convert CO2from the air into formic acid that can be used as fuel. It also does this extremely efficiently, but nobody has been quite sure how. Now researchers have an idea based on a detailed structural analysis. Research Article: Dietrich et al.

Birds, like mammals, are warm-blooded animals. This means that they can maintain a constant internal body temperature regardless of the external temperature. Unlike cold-blooded animals, such as reptiles, which rely on external heat sources to warm their bodies, birds generate their own body heat through metabolic processes.
Warm-blooded is an informal term referring to animal species whose bodies maintain a temperature higher than that of their environment. In particular, homeothermic species (including birds and mammals ) maintain a stable body temperature by regulating metabolic processes.
Apr 15, 2024 · Birds and mammals have in common a physiological feature that distinguishes them from all other animals: They are warm-blooded. That’s to say, they maintain a constant body temperature higher than the surroundings, typically 37 degrees Celsius (98.6 degrees Fahrenheit) for mammals and 40 degrees Celsius (104 degrees Fahrenheit) for birds.
The group that includes mammals and birds, both "warm-blooded" homeothermic animals (in red) is polyphyletic. Homeothermy, homothermy or homoiothermy is thermoregulation that maintains a stable internal body temperature regardless of external influence.
May 16, 2024 · warm-bloodedness, in animals, the ability to maintain a relatively constant internal temperature (about 37° C [99° F] for mammals, about 40° C [104° F] for birds), regardless of the environmental temperature. The ability to maintain an internal temperature distinguishes these animals from cold-blooded, or poikilothermic, animals, which ...
