Sorry, you misunderstood me. I wasn't very clear. The last common ancestor of all modern birds was more recent than the last common ancestor of birds and other theropods. It probably occurred before the extinction event, but not by a huge amount. Far more recent than 195 MYA. Essentially, all birds appear to be more closely related to each other than to any other dinosaur, they are a "monophyletic" group. There's no suggestion that, say, chickens could have evolved from T. rexes and ostriches evolved from some other theropod

We (Me!) don't exactly know the last ancestor of all modern birds. However, we know the one for Anatidae (Water Birds like Ducks and Geese). It was called Vegavis. It was a goose-like animal that lived in the Antarctic regions of the world at the VERY end of the Cretaceous. What does this tell us? It tells us that modern birds split up from there common ancestor at the very end of the Cretaceous Period. What was there ancestor exactly? Well, we don't know. I personally think it was a very diverse family of animals such as Dromaeosaurids or even a new undiscovered family that had traits of all the Therapods. We just have to dig and find out!

And thus I repeat, Chicguins, GO! Or Ostriguins...

Ostriches, Penguins, and Chickens are still FAR and I mean FAR from being related besides the fact that they are birds. They will most likely NEVER produce a viable offspring even if they were transmit the sperm and eggs between any of the animals.

That being said, we have evidence that Dromaeosaurs are related to todays Birds. If you watch the documentary ''Dinosaurs: Return to Life?'' then you can get a nice little explanation on how the hand of the animals are similar in embryonic stage and all that fun stuff.

I don't see how you couldn't do the same process with birds that are much closely related to eachother. If you want to make raptor-chickens by switching on hidden proteins and dna, then making a chicguin would not be any harder.

Except a Chicken did not evolve from a Penguin. They may have a common ancestor, yes, but they both followed a completely different evolutionary path.

Yeah, and I bet you that just like we could turn on the switch for claws, we could turn on a switch for flippers. If they all come from the same animals in the past, then that animal had to have had the mutation in it for all these different birds, which means with the right genetic experimentation, a chicguin is still as likely as a raptor-chicken.

I don't see what the big deal is, I was making a joke anyways. This thread is all hypotheticals, and hypothetically speaking, I want a chicguin if you get a raptor-chicken.

An ancestor of so many different animals does not carry the mutations of said animals, it gradually changes through mutations and natural selection in specific environments that would fit the new found mutation it had. A Prehistoric Chicken is in a totally different place from a Prehistoric Penguin. They came from the same animal, sure, but they were in totally different areas and mutated to suit said environment.

And yes, I know it's a joke. However, if you make me a Raptor Chicken (Which shall be named the Quaternary Dromaeosaurus), then maybe I can make you a Raptor Penguin? That would look like quite a cool animal, don't you agree?

Not a stretch to turn on dormant genes (they already have btw, check out chickens with teeth) I'm all for messing around with DNA. I believe if God didn't want us to mess with this kind of stuff we wouldn't be able to, same argument with Stem Cells (if God didn't want us to use cells that were going to be smell receptors to help a paraplegic then that girl wouldn't be able to wiggle her toes.)

Not really what scientist may have in mind. From what I understand, the Chickenosaurus will keep it's feathers, instead of being nekkid like those chickens.

I was just making a point that we have already altered the chicken by showing that picture (

naked chickens still make me giggle)

Oh ok! I so that's what you meant by the extremely nekkid chicken.

Iirc a major issue is that we cannot "bring to term" creatures that aren't being birthed by their natural parents. Even with direct cloning, scientists cloned a recently-extinct wild goat, but even with something like 150 implanted embryos, only one made it to birth--and died minutes later.

I don't know how much more of an issue it'd be with eggs; we'd have to create synthetic eggs, I'd think, which match the original creature's.

Dino's mixed up with chickens, nuff said.

I'm late to this thread, but this made me LOL. Thanks, SB!

Here's a vid of Jack Horner talking about making a Chickensaurus.
There's another youtube vid that is a bit better, but I can't seem to find it right now.
I'll post it instead if I find it. Kinda late to the thread but still love those naked chickens.

Just going to put this out there.

I have raptor-chickens free ranging out back in the yard.

Yes. You heard right.

Raptor-chickens.

We even call them The Dino Ladies for when we're referring to them as a group. You don't want to know what we call them when they are broody. They will rip you appart limb from limb. But man, I did pull off some awesome breeding with them. They survive in the wet tropics better than pure games do and certainly 100 times better than soft feathers do. Been crossing them with Australorps recently and the offspring from that is awesome. My next planned experiment is to cross them to my Brahma. The boys even taste a treat. The Old Cockers in my poultry club think I'm mad.
