If they escape into the wild and breed their offspring would be normal chickens, so they won't be a threat after one generation. They are not changing the chicken genome, they are changing how they develop in the egg using hormone treatment.
>>
>>2061359
hormones effecting gene expression can be passed down, though. How and to what extent we're still not sure. we found that out in that one experiment where mice developed an instinctual fear of certain scents in just one generation.

>>
>>2059703
>They where actually aborted before they had a chance to hatch for 'moral' reasons.
I think you mean "were."

the 'moral' reason is that they can't survive to birth.

the mutations that remove the beak also make it impossible for them to eat and probably to breathe. So if they weren't killed they'd die anyways.

we aren't anywhere near creating a chickensaurus, and that's not at all what those scientists were trying to do anyways.
>>
>>2062737
Where are you getting your information from?
>>
>>2062864
a degree in dinosaur cranial anatomy.

the hard palate (palatine bones) in birds are fused to the maxillae. If they don't fuse the bird won't be able to swallow, and without a beak it's going to have a hell of a time picking up food as well. Also since the palatines participate in the interior nares (choanae), having them floating free is very likely to cause the bird to suffocate when it's eating because it can't breathe through the nostrils.

These burds can't survive, not like that. OP's pic is enough to show the problem. It'd be like you trying to eat and breathe with a severely cleft palate or your face shattered with a baseball bat.

they don't.
they have the feather protein as embryos. Not the gene(s) for feathers.

if they had the genes for feathers that would mean feathers evolved long before dinosaurs existed, and there's no evidence at all that that's true.

the degree is technically for comparative vertebrate anatomy.

I did my thesis on Allosaurus skull morphology.

It's not a random convenience, I've been hanging out on /an/ for the dinosaur threads for years. I do take an interest in some of the discussion, some of /an/ is surprisingly bright and well-informed when it comes to dinosaurs.

There's no hidden "dinosaur DNA" inside of a chicken just waiting unlocked. They can make it look superficially like a dinosaur, but that doesn't make it one. It's not de-evolution, it's convergent evolution, the same thing that makes whale sharks look like whales despite being cold-blooded fish.
>>
>>2062737
>>2062871
I'm not saying you're wrong, but I know enough about evolution to know that it doesn't happen all at once like with the X Men. Modern day birds are obviously the result of thousands of little mutations happening gradually over time.

So at some point, there really was a "chicken dinosaur" a living flesh and blood creature that was, in essence, half modern day bird and half ancient dinosaur.

So if THESE "hybrids" wouldn't survive having a mix of both bird and dinosaur features, then how did their ancestors survive long enough to pass on the superior genes carrying the traits that allowed the modern day bird to come into existence?

Once again, not saying you're wrong, I am genuinely confused about how a species can transition from muscled jaws full of razor sharp teeth to a birds beak.

>>2061351
>pisses you off
Every egg you eat is an aborted chicken fetus
>>
>>2069791
>it's convergent evolution,
no, chickens are literally dinosaurs, and the descendents of other dinosaurs. They look like dinosaurs because they are.
>>2069799
the results of deactivating the genes for beak growth aren't equal to any stage in bird evolution.

because genes get lost and new ones show up and build on the old ones, so just deactivating one has effects on hundreds of other traits. Or thousands.

So turning off beak development produces unwanted effects that obviously weren't present when birds first evolved beaks.
>>
>>2069813
>Every egg you eat is an aborted chicken fetus
just like every sperm you cum is an aborted catholic babby.

>>2069799
Ultimately the questions you ask point to the problems we have de-evolving a chicken.

for example these scientists were excited to notice that turning off the beak development resulted in a wider snout (rostrum). The reason they were excited is because both traits, the lack of beak and the wider snout are ancestral traits. So engineering one ancestral condition also produced another.

this would at first glance seem to be significant progress and encouragement along the lines of unraveling evolution.

However the two traits evolved at very very different times and weren't ever related to each other. The narrow snout in theropods evolved BEFORE DINOSAURS EXISTED. The beak evolved long after birds evolved, tens of millions of years later.

so wide rostra and lack of beak shouldn't actually be related in any particular way, the genes that produced narrow rostra aren't the same ones that produced beaks. This means the relationship in this study isn't meaningful information about the evolution of birds. It's just a random pathology that's associated with turning off beak production.

the fact that people would see the two as somehow related from an evolutionary standpoint points to a certain naïve error in thinking about evolution. The two events weren't related and occurred at vastly different points in the animals' evolution, so interpreting them as somehow related is grossly simplifying bird evolution. This is the error behind the belief that we can de-evolve chickens: a gross oversimplification of how evolution actually affects the genes.
>>
>>2069827
trying to think how to simplify this point.

In OP's pic the scientists compare the width of the engineered chicken's snout to that of an alligator.

this implies the alligator's wide snout is ancestral, and birds and alligators share a common ancestor with a wide snout.

this is false.
the wide snout in alligators evolved quite recently and the last common ancestor between birds and alligators didn't have a wide snout.

in fact none of the ancestors or birds or alligators had a wide snout. So interpreting the wide snout as ancestral is a pretty big mistake. The similarity between alligators and the modified chicken is purely coincidental.
