Yet the same thing is found entirely within one generation of other birds as well. And not just turning scales into feathers but gradually turning legs into partial wings. Again, in one single generation.
Pigeon foot feather genes identified: Study hints how scaly dinosaur legs could get birdlike feathers
'The study found that in pigeons with feathers on their hindlimbs or feet, a hindlimb-development gene named
Pitx1 is less active than normal, while a forelimb-development gene named
Tbx5 is active in the feet, where it normally is not.
In other words, "pigeons' fancy feathered feet are partially wings," says biologist Mike Shapiro, senior author of the study published today by the journal
eLife.
In mutant pigeons with foot feathers, "the hindlimb is clearly recognizable as a leg, but it has taken on more forelimb characteristics," he says. "It's not a complete transformation of a leg into a wing. Rather, components of the leg are more winglike, including feathers and a larger leg bone."
So you've been show an example of a bird with scales, a process whereby it can happen to transform one to the other, another bird where this happens as a common mutation and we see the results in one generation caused by changes to two identified genes. Notwithstanding that there were actually some dinosaurs with feathers:
9 Dinosaurs With Feathers
'Birds are the closest relative to dinosaurs that are presently alive, and they are a
type of reptile. Birds may look different than some of the dinosaurs you see in the movies, but many species of dinosaurs had
feathers and resembled the feathered animals we see today.
In this article, you will learn about 9 dinosaurs with feathers.
Birds and dinosaurs are closely related, and feathers are a common trait that both animals share. '
To deny that this actually happens would really be perverse.
