These fish species have probably been naturally selected within their kinds since the Flood and may have lost much of their original ability to survive in more extreme temperature ranges. 14 It makes more sense to postulate that God created fish to survive in moderate temperatures, with the genetic information available to subsequently select for survival in various more extreme environments. read more
And God created great whales, and every living creature that moveth, which the waters brought forth abundantly, after their kind, and every winged fowl after his kind: and God saw that it was good.
And, behold, I, even I, do bring a flood of waters upon the earth, to destroy all flesh, wherein is the breath of life, from under heaven; and every thing that is in the earth shall die.
And the fear of you and the dread of you shall be upon every beast of the earth, and upon every fowl of the air, upon all that moveth upon the earth, and upon all the fishes of the sea; into your hand are they delivered.
