A paper saying Dingo's, Australian wild dogs, are a separate species.
I don't like this at all because biologically dingos can breed with dogs ie same species.
This is not science but social engineering conservation IMHO
Thoughts?

Species is an artificial construct try classify life forms. Since life constantly evolves, there are many instances where different forms are still related enough that they can produce viable offspring. Carried an extreme, we could say that carrots and hummingbirds are related (and, in fact, some genes are shared by plants and animals). keep the classification system useful, while acknowledging that life forms are a continuity, we have make choices. In addition species, some schemes use subspecies, or even “races.” Over time, we expect these groups continue evolve until they are truly different species. The criteria are not limited fertility; physical and behavioral separation are also elements. A group that has existed physically separate from its ancestors for hundreds of generations is legitimately a separate species. I doubt very much that “human politics” is an important factor in taxonomy.

Lots of organisms considered different species can nevertheless interbreed. Horses, donkeys, and zebras, for instance. The problem of what is and is not a species is more difficult than it might as first seem, and there are lots of borderline cases. [evolution.berkeley.edu] [en.wikipedia.org]

much in the same way homosapiens were able to interbreed with homoneanderthalis, they may indeed be a separate species but of the same genus, and therefore would still be able to procreate outside of their own individual species.

@powder They use all sorts of things to discriminate - should we stop using the word colour?

@powder You've lost me, are you saying that there is a scientific paper stating that there are different species of human in todays' societies, or that there are scientists that believe that? Or are still talking about the dingo?

@powder Right, got you now. I thought you arguing about the proper scientific terminology of species Certainly behaviour and environment can create different species but not necessarily define one. Sorry, I only glanced through the report, my bad, I'm tired.

@powder [en.wikipedia.org] This is consistent with other canids, wolves and coyotes interbreed with domestic dogs with fertile offspring.

Geographical isolation can be a factor in determining species. It's all a bit messy, as someone pointed out there can be interbreeding between cats. It's also seen in trout/salmonoid fishes.

@powder brown trout/ atlantic salmon hybrids are fertile. It's messy at some point in speciation some offspring will be fertile some won't, species are an approximation of convenience for humans. In practice it's a process.

I think they are the same genus, not species. Lions can breed with tigers, they are different species, but belong to the same genus

@powder Interestingly, I watched a program tonight about 'Pizzly Bears' (hybrid of the Polar and Grizzly) and 'Killer Bees' (hybrid of the African And European bee) and they do produce fertile offspring. I suppose it all depends on how diverse the species are. 🙂
