Scientists reveal origin of mammal evolution milestone: warm-bloodedness

WASHINGTON (Reuters) – Scientists have answered a longstanding question about mammalian evolution, examining ear anatomy of living and extinct mammals and their close relatives to determine when warm-bloodedness – a trait integral to the lineage’s success – first emerged.Researchers said on Wednesday that the reduced size of inner ear structures called semicircular canals – small, fluid-filled tubes that help in keeping balance – in fossils of m…

Warm-blooded evolved in mammalian ancestors later than previously thought

A study co-led by Portuguese paleontologist Ricardo Araújo suggests that endothermy evolved in mammalian ancestors later than previously thought, about 233 million years ago.

Animal Ears Explain the Evolution of Warm-Bloodedness

A study shows that the size of ancient animals' ear canals could crack one of the 'great unsolved mysteries of paleontology.’

Mammalian ancestors became warm-blooded later than estimated

Mammalian ancestors became warm-blooded some twenty million years later than previously estimated, according to a study by researchers who analyzed inner ear fossils to solve “one of the greatest mysteries of paleontology.”

Scientists Discover That Blood Vessels Remember Their Origins

Researchers discover that blood vessels can be tailored to specific purposes. Our family history tends to influence our future in a variety of ways. The same is true for blood vessels, according to a Weizmann Institute of Science study that was recently published in Nature. The scientists found tha
