First thing to note here is that quantifying the limits of variation would be difficult.
I agree to the point of saying it would be impossibly difficult.
Anyone can see how these can be related.
I also agree with this statement. The problem comes from the need for more detail. You, and surely every other creationist who has posted about
kinds, are always immediatley asked for a useable definition of the word. Don't you wonder why?
Lets say that your views become universally accepted. How do you, and your fellow creation biologists begin to re-write the textbooks? Yes its quite obvious that a hummingbird and an ostrich are related, but you can't write textbooks that way. How is it obvious? What defines a bird from a bat or a whale? The questions may sound stupid, but these questions have been answered in the texts - yet you reject them! So how do you suggest it be better described?
It is so simple to look and tell from whence it came.
Using your examples presented so far, I would grudgingly agree. Your method of classification is how I imagine the field of biology started out. The problem is with the incredible ammount of
things that are not obvious, those
things that defy common sense and simplistic classifications. If you cannot think of examples I would suggest that it is you that is now playing stupid.
Starfish, Anemone,
Thylacoleo, or the Virus (in all its many forms) Where do these fit? Is the starfish just a fish kind?
Thylacoleo just an odd kangaroo?
Because you demand a strict definition
And such a definition has been lacking in all creationist writings thus far. I believe it to be impossible and would instead be satisfied with an example by example exploration of "kinds". Taken on a case by case basis I still feel that "kinds" either requires lightning fast evolution or a very very sophisticated ark.
You desire the how, I know the why.
Interesting how you can see so clearly that there is two different topics of discussion. Two totally different things aren't they?
Hows and whys, sort of like black and white, night and day, science and religion.
