Prior to their existence on birds, feathers were present on the bodies of many dinosaur species. Through natural selection, feathers became more common among the animals as their wings developed over the course of tens of millions of years. [6] The smooth surface of feathers on a bird's body helps to reduce friction while in flight.
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.
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.

Over 40% of key traits found in modern birds evolved during the 60 million year transition from the earliest bird-line archosaurs to the first maniraptoromorphs, i.e. the first dinosaurs closer to living birds than to Tyrannosaurus rex. The loss of osteoderms otherwise common in archosaurs and acquisition of primitive feathers might have ...
No, domestic turkeys (aka the ones that are raised on farms) cannot fly. Because they spend their lives growing up on locations where they have no natural predators and likely without trees to ...
A wild turkey is Ohio’s largest upland game bird. This bird can grow up to four feet tall and weigh up to 24 pounds, according to ODNR’s website. They have featherless heads and slim, long necks.
The male turkey, or tom, is puffing his chest and spreading his feathers in an effort to attract the female turkeys, or hens, to mate. Stewart would know; he was a big part of it.
