The Origin and Diversification of Birds - ScienceDirect -  · This expansion began early in theropod evolution and non-bird paravians had the highly expanded, and presumably ‘flight ready’, brain of early birds . Modern birds also possess an efficient ‘flow through’ lung in which oxygen passes across the gas exchange tissues during inhalation and exhalation, and which is linked to a complex system of balloon-like air sacs that store air outside

Bird - Wikipedia - Wing shape and size generally determine a bird's flight style and performance; many birds combine powered, flapping flight with less energy-intensive soaring flight. About 60 extant bird species are flightless, as were many extinct birds

Archaeopteryx - Wikipedia - Archaeopteryx (/ ˌ ɑːr k iː ˈ ɒ p t ər ɪ k s /; lit. 'old-wing'), sometimes referred to by its German name, "Urvogel" (lit. 'original bird' or 'first bird'), is a genus of bird-like name derives from the ancient Greek ἀρχαῖος (archaīos), meaning "ancient", and πτέρυξ (ptéryx), meaning "feather" or "wing".Between the late 19th century and the early 21st

The History of Animal Evolution - University of Waikato - The evolution of amphibians. By the Devonian period two major animal groups dominated the land: the tetrapods (4-legged terrestrial vertebrates) and the arthropods, including arachnids and wingless insects. The first tetrapods were amphibians, such as Ichthyostega, and were closely related to a group of fish known as lobe-finned fish Eusthenopteron

Archaeopteryx (dier) - Wikipedia - Archaeopteryx is een basaal geslacht van uitgestorven vogels die 150 miljoen jaar geleden tijdens het late Jura leefden in het gebied van het huidige Duitsland. Archaeopteryx is een van de oudste bekende vogels en oudste bekende vliegende dinosauriërs en wordt ook wel de Oervogel genoemd. In 1861 werd het fossiel van een veer beschreven dat de naam Archaeopteryx kreeg, "oerveer". Datzelfde

Bird flight - Wikipedia - Bird flight is the primary mode of locomotion used by most bird species in which birds take off and assists birds with feeding, breeding, avoiding predators, and migrating. Bird flight is one of the most complex forms of locomotion in the animal kingdom. Each facet of this type of motion, including hovering, taking off, and landing, involves many complex movements

Archaeopteryx - Wikipedia - Archaeopteryx visse durante i primi del Titoniano, durante il Periodo Giurassico, circa 150 -148 milioni di anni fa. La maggior parte degli esemplari furono scoperti nei depositi di calcare di Solnhofen, in Baviera, formazione nota soprattutto per l'incredibile stato di conservazione dei fossili.. Archaeopteryx raggiungeva le dimensioni di un corvo; con ampie ali arrotondate alle estremità e

Albatross - Wikipedia - When taking off, albatrosses need to take a run up to allow enough air to move under the wing to provide lift. [15] The dynamic soaring of albatrosses is inspiring to airplane designers; German aerospace engineer Johannes Traugott and colleagues have charted the albatross's nuanced flight pattern and are looking for ways to apply this to aircraft, especially in the area of drones and unmanned

Bird anatomy - Wikipedia - Bird anatomy, or the physiological structure of birds' bodies, shows many unique adaptations, mostly aiding have a light skeletal system and light but powerful musculature which, along with circulatory and respiratory systems capable of very high metabolic rates and oxygen supply, permit the bird to fly. The development of a beak has led to evolution of a specially adapted
