Using the largest and most informative molecular phylogenetic dataset ever analysed, evolutionary biologists were able to construct a new phylogenetic tree of jawed vertebrates. This new tree resolves ...

From the 20-foot-long jawbones of the filter-feeding blue whale to the short, but bone-crushing, jaws of the hyena and the delicate chin bones of a human, the pair of lower jawbones characteristic of ...

Paleontologists have recreated the cranial structure of a 308-million-year-old lizard-like vertebrate that could be the earliest example of a reptile and explain the origin of all vertebrates that ...

A new study reveals the surprisingly convergent evolution in the inner ear of mammals. An international research team led by Nicole Grunstra from the University of Vienna and Anne Le Maître from the ...

This story was updated at 11:00 AM June 1 The basic decision-making circuitry underlying social behaviors such as fighting and mating is incredibly similar in all vertebrates, from fish to mammals, ...

Nov. 21 (UPI) --The research is clear, the physiological complexity that makes modern humans -- and other mammals -- unique from simpler species is a product of gene regulation, not genet quantity.

Invasive mammals on islands pose severe, ongoing threats to global biodiversity. However, the severity of threats from different mammals, and the role of interacting biotic and abiotic factors in ...

The Juan Fernandez firecrown is endemic to Robinson Crusoe Island. Key threats to this critically endangered species include habitat loss, due in part to invasive herbivores, and predation by invasive ...

Eight of every ten species extinctions has occurred on islands, and invasive mammals are the leading reason for those losses. Currently, 40 percent of species at risk of global extinction are island ...
