These new mutations are really cool. Some beautiful birds! I saw a thing on TV about a genetic experiment in Russia that has been going on for the past 50 years. They are trying to track down the origin of dogs. We have known for a long time that the domestic dog is descended from the wolf. The question is- how did the wild wolf- this big, aggressive creature that has a distinctive look- turn into a little chihuahua or a pekingnese or a St. Bernard?
50 years ago (it was the USSR back then) Russian scientists took wild foxes, penned them and started to selectively breed them. They bred them to be less aggressive. They bred the human-friendly foxes with each other and the foxes that would not warm to humans with each other. That was 20 generations of foxes ago. The aggressive foxes changed little in that time. The current generations of foxes look very much like the first generations did back in the 50's. But the less aggressive foxes are undergoing changes not only to general personality (like you'd expect) but also physical changes to the way the foxes look.
The "domesticated" foxes (the scientists have begun to sell some of the foxes as pets believe it or not!) have become slimmer, they are changing colors (the foxes were silver foxes originally but now are showing up in all kinds of colors) and developing dog-like traits in how they relate to humans. Now play this out for 10,000 years and it doesn't take much imagination how dofferent breeds of dogs came to be.
How does this relate to parrots? I can see different breeds of parrot developing now that parrot-ownership is widespread and breeding is common. I wonder if these mutations are the beginning of that process in birds?
