pffttt you are all forgetting the most important part.

How does this relate to animals being more edible!?

Could you imagine your favorite meats being combined in one animal?? Some CowPig thing or some kind of omni-sushi!

Sweet, another opportunity for that soon to be Ph.D in biochemistry to get put to use on here.

What it really boils down to is:

1) Can they physically mate (which can be bypassed by artificial insemination, in vitro fertilization...ect ect). While genetically, a toy poodle and a great dane could produce offspring, physically it just isn't going to happen (and if it I'd feel sorry for that poor poodle)

2) Genetics. We can go by number and size of chromosomes, locations of essential genes, lethal autosomals, and general lack of fitness for survival (mules being sterile...ect)

Now, should you be hell-bent on having a pet piglizard, it is more possible than you may think. Modern labs create chimeric animals far more often than most people are aware of. Some of you may remember the link on DailyTech about the "clones" extinct (tasmanian tiger I think). The disappointing part about this is that at this point in time, we are simply swapping in a copy of a HIGHLY similar gene (think something highly conserved throughout animals, like hemoglobin or insulin or something along those lines). While technically the resulting animal is genetically constituted from 2 animals, the phenotype (outward, physical appearance) is indiscernible from any "normal" specimen. Some day, however, we may be able to splice more interesting genes in. Think of the cuteness factor of a puppy-kitten or the badassery super villain-esque Bear-horse

You needed a PhD in biochem to recite freshman bio? (just ball-busting)

I'm finishing a microbio masters and might do a micro/immunology/biochem phd in the near future - just wondering what you plan on doing after you finish? academic/industrial research?

Perhaps you guys should read up on the scientific definition of the word "species"...

You can mate all your want--having offspring might be a problem.

One exception would be Horse + Donkey = Mule

Though....mules are not capable of reproduction.

Dogs and Wolves/Coyote's can interbreed and their offspring are fertile.

You say one exception yet have others listed.

proof.

more

Well the question asked for species to species. You can't say one is the same as another if they are indeed classified differently.

Also along with chromosome matchup and physical mechanics, a lot has to do with if the sperm can pentrate the host's egg, can the sperm live long enough to make it to the egg, and a slew of other simpler issues.

I think he was just trying to give a quick and easy answer without going into the specifics of pre and post zygotic barriers.

Very interesting.
Any links to documented cases of these chimeras?

my previous job, which I only recently left, was making chimeric mice. Nothing spectacular. Funky colors, some with some neurodevelopmental disorders perhaps, but they just look like mice. Quite expensive to make, though...

if so he over complicated it. A species is indeed a species though...hardly a splitting hairs situation.

Yeah, I guess dogs would be one of the biggest exceptions. Can all dogs mate with all other dogs theoretically?

Well we have crap like labradoodles, etc. Lots of different breeds, not sure if they all work interchangeably, but that would be interesting.

Dogs are essentially all the same species iirc. I don't think a lab, poodle, or even huskies or german shepherds are considered different species. Just bred for distinct purposes, and they all came to creature different lines of different looking animals, aka breeds. It might, in one sense, be comparable to the different 'races' humanity has, with things like hair, eye, and skin color, and even height, being different among the different 'races'. We are all the same race, mankind, but have different appearances based on, well... selective breeding.

Thats when you get into species lines , and sub-species , and geographic variants and line bred variants. Most dog breeds are line bred to favor certain traits. over time you get a "breed" that breeds true.

Guys if you want to see some crazy hybrids check out Flowerhorns.

All dogs are the same species. Canids (dogs, wolves, foxes, coyotes, etc) in general are all closely related genetically and IIRC can interbreed. While science believes that dogs evolved from the domestication of wolves, an interesting study I recall is a Soviet scientist who experimented specifically with making foxes more tame and within just a few generations had a dog. Very flexible DNA throughout that whole family.

The foxes kept the puppy state. I cant explain it properly. It took less than 30 generations and he produced perfectly domesticated foxes. The behavior of the tame animals is that of a puppy, compared to an adult animal who may challenge its owner.

I almost feel embarrassed about it, but I plan to stay in academia. I've spent the last 5 years working as a tutor for the university, taught a few classes (gave lecture, organized labs) and it is just something I really enjoy. I'll certainly be making far less per year, but I just don't see myself as content with my position at a drug company of some sort. My emphasis is in pharmacology by the way. For some unknown reason, a large number of my peers are selecting cancer (in terms of mechanisms and whatnot) as their emphasis. I couldn't see myself working to cure a disease that provides my occupation. Once your goal in life is complete, you're out of a job. Back back on topic, how about a cow-horse. Sounds useless, but you make walking behind it with a shovel a punishment. Crime rates would drop like crazy, becuase you know that thing would live to s***.

That 2-part Nature (or was it Nova) on dogs was pretty damn interesting and they touched on that experiment. Was an interesting theory on how early man may have domesticated the dog.

There has never been a confirmed report of a fox hybrid with another canids. Also foxes have only 34 chromosomes compared to other canids which have 78.

As far as I know its coyotes and wolves and dogs which can breed. Foxes cannot, you are correct. Some breeds of dogs have incompatible genes when bred with other types of dogs. The puppies have a low survival rate.

It makes me glad that I only have to train and deal with oversized puppies with inferiority complexes. My dogs could kill me if they wanted to.

I had a 15 pound terrier when I was growing up. He was 13 years old and my dad had let him outside to run around the neighborhood. My dad said he didn't know where he went, so he started looking around for him and found him across the street... Our neighbor had a great dane and our dog had somehow coaxed this huge dog to lay on its back while he did the deed.

....the owner took his dog to the vet the next day to get her 'fixed'. Just saying, any breed can mate with any breed...
