Wow, we have alot of geneticists on this site. I'm feeling kinda dumb right now.:eek: Great reading though, thank you.

I thank whoever bumped my thread. All these new posts are very interesting. I knew about the red blood cells lacking cDNA, but I love reading about genetics and embryology.

Hmm.. this is very interesting, the whole chicken can become a dinosaur-abomination thing. It requires a lot of control at every stage to manipulate an organism to resemble a species other then itself. I totally buy that we could turn on certain genes, turn off certain genes, have hundreds of generations of selective breeding and end up with a 'dinosaur' (more likely a dinosaur look-a-like). But we could also manipulate a chicken to look like a penguin by the same means, or an albatross. We could make humanoid dogs too!

But Im confused as to how this demonstrates evolution as a whole. Doesn't this just show the power of DNA? That all animals have genes that they don't need to be successful, and genes that they pass on that may never be needed? Incredible!

Something that has always intrigued me is our dog breeds. All dogs are still a member of the same species, they can successfully interbreed (a Chiwawa couldn't bear great dane puppies, but a great dane could bear chiwawa puppies...etc). How much longer until we have multiple species? Where crossbreeding only produces infertile hybrids?

This has always been my ponder about evolution: If you have a line of 1000 generations, gen. 1 can breed with gen. 300, 300 can breed with 600... but can gen. 1 breed with 600? Also would 1000 generations of separation in mildly different areas produce two species? how long would this take? I mean Evolutionarily speaking donkeys and horses were the same at one point, now they are not.. but they still produce a mule, could we turn a donkey into a horse, that can breed with a horse, and produce a horse? I'm skeptical...

Any thoughts? no articles please....

If this Chickensaurus can always breed with a chicken, it's nothing more then a freak chicken no?

If you really want to know, read Coyne and Orr's book "Speciation". It's not perfect but its the best one stop shop for speciation information. The general population has a very misinformed view of how new species are formed and what constitutes a new species. Without an understanding of the fundamental basics, it's hard to enter any dialogue on how new species arrive.

Times like these I wish I paid attention in biology class...

I swear I read in Maclean's magazine that they were going to use reptile DNA (not dinosaur) with the chicken, and produce scaly chickens that would somewhat resemble dinosaurs. At the very least they could produce a TV show and the general public would be none the wiser.
