Think about it. Let's say there was 7 majorly different bird species taken on the Ark.
So, perhaps, seven "created kinds?" Look at your book, in Deuteronomy chapter 14:
11Of all clean birds ye shall eat. 12But these are they of which ye shall not eat: the eagle, and the ossifrage, and the ospray, 13And the glede, and the kite, and the vulture after his kind, 14And every raven after his kind, 15And the owl, and the night hawk, and the cuckow, and the hawk after his kind, 16The little owl, and the great owl, and the swan, 17And the pelican, and the gier eagle, and the cormorant, 18And the stork, and the heron after her kind, and the lapwing, and the bat.
How many "kinds" are specifically named there, and how many more implied? And that's only "unclean" kinds, Mike.
"The wretched world lies now under the tyranny of foolishness; things are believed by Christians of such absurdity as no one ever could aforetime induce the heathen to believe." - Agobard of Lyons,
