It isn't irrelavent when you make a statement that species is silly, whatever you propose as an alternative must be LESS silly otherwise you're a hypocrite. Which is exactly what, in every conversation, you reveal yourself to be.
I am under no obligation to reveal any alternative and I am utterly justified in calling silly what I consider silly and providing good reason. I have done that. Species is a silly term, vague and malleable. Your response is to launch into an assault upon the term "kind" which is clearly defined and very understandable.
This has nothing to do with hypocrisy on my part and everything to do with your inability to involve yourself in civil and rational discourse.
The definition includes "potentially interbreeding".
I know. It equivocates.
Scientists don't call the same species that lives on different continents different species just because they don't usually interbreed due to distance.
Never said they did. :idunno:
Sure it does. If it's a definitive classification you should be able to tell me what is a kind and what isn't very easily.
Nope. You're flat out wrong. Having a definitive classification system and the process of classifying individuals are two utterly distinct things.
You need to think things through a little more carefully.
You're the one using common ancestry as the basis for your categorization. You should know that biologists know that ALL organisms share a common ancestor if you go back far enough, so using that as a distinction is truly meaningless.
Only if you first assume the truth of your evolutionary theory.
Not consistently as one group breeds with another. Ligers are consistently larger than either parent, whereas tigons are consistently smaller than either parent. That tells you there's some serious genetic difficulties between the two groups.
Yeah...
Growing larger isn't necessarily a good thing.
And living longer?
There's an imbalance of growth hormones.
Or maybe it's just a different balance. They don't seem to have any trouble surviving. :idunno:
nor do they happen naturally at any frequency at all outside of a zoo.
Just like the offspring of Mbuti and Inupiat. :idunno:
Y hasn't shown me any evidence that contradicts evolution.
:rotfl:
The genetics are obvious, regardless of the obviousness of the morphology.
Platitudes - the proud domain of the evolutionist.
Perhaps you don't understand the concept of "family resemblance".
And perhaps you're over-stating your case.
I guess the fact that humans resemble each other is no evidence they share a common human ancestor either. All those human races must have been separately created then, according to your logic, there's no evidence they are related.
:rotfl:
Where do you get these stupid ideas?
