Sensory receptors are at the interface between an organism and its environment and thus
represent key sites for biological innovation. Here, we survey major sensory receptor …

The evolutionary history of sour taste has been little studied. Through a combination of
literature review and trait map** on the vertebrate phylogenetic tree, we consider the …

NEW YORK TIMES BESTSELLER• A “thrilling”(The New York Times),“dazzling”(The Wall
Street Journal) tour of the radically different ways that animals perceive the world that will fill …

We present a draft genome of the little bush moa (Anomalopteryx didiformis)—one of
approximately nine species of extinct flightless birds from Aotearoa, New Zealand—using …

Complex vocal learning, a critical component of human spoken language, has been
assumed to be associated with more-advanced cognitive abilities. Tests of this hypothesis …

Taste perception plays an essential role in food selection. Umami (savory) tastes are sensed
by a taste receptor complex, T1R1/T1R3, that detects proteinogenic amino acids. 1 High …

The ability to manipulate objects with limbs has evolved repeatedly among land tetrapods.
Several selective forces have been proposed to explain the emergence of forelimb …

Organismal adaptations are the hallmark of natural selection. Studies of adaptations in avian
systems have been central to key conceptual and empirical advances in the field of …

Taste or gustation is the sense evolving from the chemo-sensory system present in the oral
cavity of avian species, which evolved to evaluate the nutritional value of foods by detecting …

Taste is a vital chemical sense for feeding behaviour. In mammals, the umami and sweet
taste receptors comprise three members of the taste receptor type 1 (T1R/TAS1R) family …
