Example: "Birds like penguins have evolved to be excellent swimmers, while birds of prey have sharp talons and keen eyesight for hunting." 15. Birds in Art and Literature: Talk about birds' representation in art, literature, or cultural symbolism. Example: "In many poems and songs, birds ar...
Birds (far right) evolved from theropod dinosaurs. (Image credit: Micha Weber via Shutterstock) Why don't birds look like other reptiles? The connections between birds and their scalier kin might have been easier to grasp if there hadn't been a mass extinction event 66 million years ago. ...
These birds evolved from flying ancestors but lost their ability to fly, instead adapting to life on land or in the water. But why did they give up flight? Why don't all birds fly? The ability to fly is especially useful for escaping predators and traveling long distances in search of ...
Ultimately, Abzhanov said, the way the bird skull evolved — through changes in the developmental timeline — highlights the diversity of evolutionary strategies that have been used over millions of years. “That you can have such dramatic success simply by changing the relative timing of events ...
Birds have evolved different types of feathers to survive different climates.【4】So many birds leave the Arctic producing grounds, for example, when temperatures begin to fall and they need warmer habitats. Similarly, the hottest regions can be a bad environment for raising little chicks, and ...
Abstract As a physiological tactic to temporarily escape the brunt of cold and shortage of food and water, many mammals and birds have evolved the ability to exhibit torpor. Torpor in these heterothermic endotherms is characterized by a periodic, facultative lowering of the “thermostat” for body...
These studies will help to explain how those birds have evolved a unique brain with its structure different from mammals but with comparable intelligence, or at least not inferior to. Author contributions XN: conceptualization, funding acquisition, original draft, review and editing; ZJ: ...
Birds probably evolved from meat-eating (theropod) dinosaurs during the Mesozoic Era, roughly 150 million years ago. Early birds, like Archaeopteryx, had teeth in their mouth and claws on their wings. Bird Songs: Birds sing beautiful and diversified songs. Many songbirds are becoming scarcer ev...
In summary, the retina of flycatchers from a single Family of songbirds have evolved a novel cellular structure in a photoreceptor that may confer some benefits in terms of detecting, tracking, and capturing fast-moving prey. Potential future approaches to establish the function of this structure ...
(Supplementary Fig.2). While in the VS system these color points map toward thevvertex, in the UVS-visual system they map towards theuv-sedge and theuv-s-lface. Such color vectors that contribute to expanded color volume of the VS gamut could have evolved by sexual or social selection ...
