Jeff,
people do like to get hung up on name tags for things and the scientific community make it a game of ring a ring a rosie, scientific nomencalture (naming) debates go back n
forth wth all manner of scientific reasons (arguments) why this should be that genus or species or sub species.
One would think -
well it can't really be that hard - but I can tell you it CAN be harder than you think.
In all honesty there's a tendency for some in the scientific community to think that "immportantality" (a morbid cross between immortality and self importance) awaits them if they can present an argument that something old is made new again and hence then named after them.
Speciation isn't THAT difficult, in some cases.
Basically to be the same species - the animals need to be able to meet in the wild - mate and produce fertile offspring.
Sounds easy enough...at first glance.
So..a Red Deer From Scotland - isn't the same species as a Canadian elk.
For a start they are two different continents - so they can't meet in the wild to reproduce....hence they are different species.
Heres the rub tho - when you release them both into the Wilds of New Zealnds mountains together they interbreed and produce fertile offspring - the hybrids being called locally Wapiti - the maori name for them.
But we are happy they are different species - because it is easy - they can't meet in the wild - because they come from 2 different continents, so they remain separate species.
That's all
well n good.
What if they were birds, tho - and had wings and could fly between the 2 continents - then technically they WOULD be the same species, because the separation of landmass by ocean is no barrier to birds that fly (or worse, fishes that swim).
So because those two deers are mammals and can't swim - even tho they are similar enough to be able to produce fertile offspring we conclude they are different species, yet were they birds we'd have a bet the other way and call them the same species...
Now if they were fish - then the oceans are contiguous (without boundary) around the world so now there are no barriers, and we find the Japanese Red Snapper, the American Porgie, and the Australian pink snapper, instead of being 3 separate species as was thought for 100+ years - are now in fact all "Pagrus auratus"....pink snapper.
Speciation isn't always as simpe as we think - and this need to hang lables on everything can get very wearying when you get right down to it, in the insect and plant worlds etc
Trees is tough enough - wait till you try birds then fishes & insects!
Red gum works for me - & I could live with that description.......who among us from the photo can identify the flowers nuts and seeds down to species level from a scenery photo - all I can say is the claimiant has better eyesight then me Gungadin.
Cheers
