The basal bird Archaeopteryx, from the Jurassic, is well known as one of the first "missing links" to be found in support of evolution in the late 19th century. Though it is not considered a direct ancestor of modern birds, it gives a fair representation of how flight evolved and how the very first bird might have looked.
Felis lunensis was one of the first modern Felis species, appearing around 2.5 million years ago in the Pliocene. Fossil specimens of F. lunensis have been recovered in Italy and Hungary . [ 1 ] Fossil evidence suggests the modern European wildcat Felis silvestris may have evolved from F. lunensis during the Middle Pleistocene. [ 2 ]
A turning point came in the early twentieth century with the writings of Gerhard Heilmann of Denmark.An artist by trade, Heilmann had a scholarly interest in birds and from 1913 to 1916, expanding on earlier work by Othenio Abel, [12] published the results of his research in several parts, dealing with the anatomy, embryology, behavior, paleontology, and evolution of birds.

Birds (and their more reptilian cousins, the Crocodilia) are the modern-day legacy of dinosaur’s 165-million-year-long stint on Earth. While our avian friends’ Mesozoic origin story isn’t up ...
Each of the roughly 11,000 species of birds on Earth today is classified into one of two groups, based on the arrangement of their palate bones. Fossil ‘overturns more than a century of ...
The evolutionary origin of birds was an open question in paleontology for over a century, but the modern scientific consensus is that birds evolved from small feathered theropods in the Jurassic. Not all dinosaur lineages were cut short at the end of the Cretaceous during the Cretaceous–Paleogene extinction event , and over 11,000 species of ...

Cats hunt small prey, primarily birds and rodents, [135] and are often used as a form of pest control. [136] [137] Other common small creatures, such as lizards and snakes, may also become prey. [138] Cats use two hunting strategies, either stalking prey actively, or waiting in ambush until an animal comes close enough to be captured. [139]
