For over a century, scientists have puzzled over a fundamental mystery in our evolutionary history: how did mammals go from sprawling like lizards to striding like cats and dogs? This transition—from ...

Around the world, women outlive men by an average of around 5.4 years. A distinction in life expectancy between sexes is surprisingly common among other mammals, too, though it's not fully understood ...

"Return to the Sea portrays the life and evolutionary times of marine mammals--from giant whales and sea cows that originated 55 million years ago to the deep diving elephant seals and clam-eating ...

Studying ancient mammals helps scientists understand how life evolved and adapted over millions of years. Fossil discoveries provide valuable insights into extinct species, revealing their behaviors, ...
