Yet another huge argument against evolution. Chickens started out as a 1-lb jungle fowl and were bred into a 7-lb meat animal but still have the 1-lb bird’s wings. You’d think it would be easy for some small number of them to evolve wings adequate for the 7-lb bird and start flying better, but it never happens. In real life, there’s no such thing as gaining new functionality on a macro level.
Only if "huge" and "specious" are made interchangeable.
The vast majority of modern chickens have no survival need to develop bigger and better wings as they spend their life in confined quarters and never live long enough to even learn how to fly. So their wings do not evolve. But where chickens are allowed to roam and run they do develop wings that can take them out of harm's way. For example, the chickens that roam around Luckenbach, Texas are famous for flying up into the big oak trees (and crowing annoyingly during the music). That's something a Pilgrim's Pride chicken could never do.
Why would they need to? If they stay right where the are, somebody comes and feeds them every day. If they flew away, they'd more likely be killed and eaten in the wild. For a domesticated chicken, there's no survival advantage in being able to fly.
Lizards Rapidly Evolve After Introduction to Island
In 1971, scientists transplanted five adult pairs of the reptiles from their original island home in Pod Kopiste to the tiny neighboring island of Pod Mrcaru, both in the south Adriatic Sea...I'd say that a brand-new structure that enables the animal to change its diet is more impressive than growing bigger wings.In 2004, however, tourism began to open back up, allowing researchers access to the island laboratory.
"We didn't know if we would find a lizard there. We had no idea if the original introductions were successful," Irschick said....
The transplanted lizards adapted to their new environment in ways that expedited their evolution physically, Irschick explained.
Pod Mrcaru, for example, had an abundance of plants for the primarily insect-eating lizards to munch on. Physically, however, the lizards were not built to digest a vegetarian diet.
Researchers found that the lizards developed cecal valves—muscles between the large and small intestine—that slowed down food digestion in fermenting chambers, which allowed their bodies to process the vegetation's cellulose into volatile fatty acids.
"They evolved an expanded gut to allow them to process these leaves," Irschick said, adding it was something that had not been documented before. "This was a brand-new structure."
