- leoc 13y agoIndeed not, apparently: https://en.wikipedia.org/wiki/Sheep%E2%80%93goat_hybrid https://en.wikipedia.org/wiki/Sheep%E2%80%93goat_hybrid They're six chromosomes out from each other, to begin with.
- ShaneOG 13y agoGoat + Wheel = Gwheel, Whoat ?
- ChuckMcM 13y agoI would be surprised to see a hybrid of horses and cats but it would certainly be the ideal gift kitten AND a pony! Wondering if they pronounce 'geep' as "gee eep" or "jeep".
- grey413 13y agoGoat and sheep lineages diverged approximately five to eight million years ago[1]. For reference, human and gorilla lines diverged roughly six to eight million years ago[2]. Also, different breeds of dogs are considered the same species (and likewise with cats).

- jeremyjh 13y agoThere are multiple species of cats (e.g. domestic, bobcat, leopard) and some can interbreed.
- xahrepap 13y agoThere was a Liger at the local Zoo out here in Utah. It died before I was born, but they had it stuffed and on display for years. No mystical powers though.
- giardini 13y agoHumans and gorillas? What about our ancestors and those of pigs? I found this hypothesis fascinating: "A chimp-pig hybrid origin for humans?" http://phys.org/news/2013-07-chimp-pig-hybrid-humans.html http://phys.org/news/2013-07-chimp-pig-hybrid-humans.html from the article: " I asked McCarthy if he could give a date estimate for the hybridization event, he said that there are a couple broad possibilities: (1) It might be that hybridization between pigs and apes produced the earliest hominids millions of years ago and that subsequent mating within this hybrid swarm eventually led to the various hominid types and to modern humans; (2) separate crosses between pigs and apes could have produced separate hominids (and there's even a creepy possibility that hybridization might even still be occurring in regions where Sus and Pan still seem to come into contact, like Southern Sudan)."
- Noishe 13y agoThere isn't enough attention to this in my opinion. When you research it, everything lines up so nice.
- Steuard 13y agoThat's one of the most ridiculous things I've ever read. We've done genetic studies on humans and apes, and we share some huge fraction of our genome with them (99%+, right?). It's quite telling that in this era of abundant genetic data, this guy bases all of his arguments on anatomical similarities and says nothing about genetics. It's all but impossible that a link like what he's suggesting would have been overlooked if pigs had made any significant contribution to the human genome. (Just for example, we've got all sorts of estimates of species divergence dates among primates based on genetic data that should have given nonsensical results if there had been massive influxes of pig DNA in the middle of that history.)
- Blahah 13y agoSpecies don't necessarily have to be that closely related to hybridize. Compatibility is usually more complex but sometimes surprisingly more crude (when related simply to chromosome number) than a linear scaling with evolutionary time. Goats and Sheep are both in family Bovidae subfamily Caprinae. The species diverged around 7 million years ago [0]. Intra-familial (but inter-generic) hybrids are fairly well-known (savannah cats, zedonks, etc.). Much more surprising is that people have reportedly successfully created hybrids [1] between chickens (family Phasianidae) and guinea fowl (family Numididae), which diverged around 50 million years ago [2]. Note that http://timetree.org http://timetree.org is a beautiful service for finding out how closely related two species are (in evolutionary time).

- drcode 13y ago> Hybrids between species of horses and cats are common Yes, they're called "hats" or "corses".
- adamnemecek 13y ago> Hybrids between species of horses and cats are common. I was really confused for a second there.
- cwal37 13y agoDogs are one species. Their variation is a result of long-term purposeful breeding and a "slippery" genome. Similar deal (not so much the slippery genome) for horses and housecats. I think you're confusing breeds with species.
