This Week: Did birds evolve from dinosaurs, as students are being taught? They are gorgeous in their complexity, delicate in their construction, and yet strong enough to hold a bird thousands of feet in the air. As with any question of evolution, the core facts are simple: parakeets and other parrots are intelligent because, over the millennia, intelligent birds got to pass on their genes to the next generation, at the expense of less intelligent competitors. from flaming arrows, drum beats, smoke signals, messenger pigeons, to modern satellite enabled communication devices.

Long before Darwin, the rock doves of Mesopotamia and Sumer flocked to the fertile fields, pecking at seeds, and were soon encouraged to roost in nest-houses in cities and on farms. In other words, pigeon breeders produced crests on the birds on five separate occasions.

Noah released a dove from his ark, which returned to him. Unfortunately, this meant manually transporting large amounts of pigeons in one direction, before having them released with a message attached to their leg, hoping that they would return to the original location. Researchers have found that mutations in pigeon DNA can control a variety of traits, including the directions their feathers grow, like in this Jacobin pigeon. Posted by Brian Mariani on Apr 24, 2018 in Creation Nuggets | 0 comments “Darwin’s work actually demonstrates how the intense selection pressures after the Flood could have acted on gene pools rich in variety to allow rapid speciation/adaptive radiation from the restricted number of land-dwelling kinds represented on the Ark. Unrelated research in 2016 published in the journal Evolution looked at bird and crocodile anatomy and sounds and … Take a closer look at the history of pigeons and how they evolved into pests in urban centers and residential areas here.
