A 2007 survey of over 55,000 people found that chronotypes tend to follow a normal distribution, with extreme morning and evening types on the far ends. [6] There are studies that suggest genes determine whether a person is a lark or an evening person in the same way it is implicated in people's attitude toward authority, unconventional behavior, as well as reading and television viewing ...
Early bird study focused on collectibles such as eggs and nests. The emergence of ornithology as a scientific discipline began in the 18th century, when Mark Catesby published his two-volume Natural History of Carolina, Florida, and the Bahama Islands , a landmark work which included 220 hand-painted engravings and was the basis for many of the ...
UCT scientists published the results of their study last week in the journal PLOS ONE. “Fossil tracks of early birds and theropods, the co-existing dinosaurian ancestors of birds, co-occur in ...
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.

Being an early bird is even linked to having a longer life. A Chronobiology International study published earlier this year followed nearly 24,000 twins from 1981 to 2018 and asked them about ...
The study shows that the length of birds' lower leg bones (an indicator of body sizes) shortened by an average of 2.4% and their wings lengthened by 1.3%. The findings of the study suggest the morphological changes are the result of climate change, demonstrating an example of evolutionary change following Bergmann's rule. [26] [27] [28]

The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. The study of birds is called ornithology. Birds are feathered theropod dinosaurs and constitute the only known living dinosaurs.
