"Kind" - the great escape word of the Creationist. You could, they say, fit every animal on the Ark because you only need each kind.
"14: And the vulture, and the kite after his kind;
15: Every raven after his kind;
16: And the owl, and the night hawk, and the cuckow, and the hawk after his kind,
17: And the little owl, and the cormorant, and the great owl,
18: And the swan, and the pelican, and the gier eagle,
19: And the stork, the heron after her kind, and the lapwing, and the bat.
20: All fowls that creep, going upon all four, shall be an abomination unto you.
21: Yet these may ye eat of every flying creeping thing that goeth upon all four, which have legs above their feet, to leap withal upon the earth;
22: Even these of them ye may eat; the locust after his kind, and the bald locust after his kind, and the beetle after his kind, and the grasshopper after his kind.
23: But all other flying creeping things, which have four feet, shall be an abomination unto you."
Leviticus 11: 14-23
Doesn't this rather imply that whatever a biblical Kind may or may not be, it isn't a broad category? Locust and bald locusts are different kinds, little owls and great owls are different kinds, and so forth.
