Evolution takes some weird twists and turns to bring animals to their current forms. While evolution is based on random ...

The living mammal family tree is full of diverse species–big blue whales, great apes, bats, rodents, and humans, to name just a few. The early evolution of mammals is a little bit murky ...

The new research could upend what’s known of the evolution of the most primitive mammals alive today. Found in Australia and New Guinea, the platypus and echidna are called monotremes ...

but the researchers said they are excited that their work will help to answer one of the longest-standing questions about the evolution of mammals. "The origin of mammalian endothermy is one of ...

“The reorganisation of synapsid jaws through this time has long been known as a big step towards the evolution of mammals,” added Dr Armin Elsler, a collaborator on the study. “These changes ...

"The origin of endothermy in the mammalian lineage actually precedes the origin of mammals," Araújo says. In addition, the evolution of mammal-like warm-bloodedness in these extinct species did ...

"Our findings challenge conventional views on upper jaw evolution," the researchers said in a statement. Compared with our distant cousins the reptiles, the faces of mammals are made more complex ...

Terrestrial mammals have hundreds of olfactory receptors ... are only just beginning to plumb the genetic depths of cetacean evolution. Now, with dozens of cetacean genomes available to study ...

They traced the behavior’s evolution across mammals and tested for any evolutionary relationships with other behaviors. The team found that same-sex sexual behavior is widespread across mammal ...
