Marine Mammals

Dr. Jackson, Why are dolphins and whales considered mammals? Doesn't this help the evo crowd? Didn't GOD make the birds and fishes (whales) on day five Genesis 1:21 and mammals (land animals) on day six? GW

note to readers: yes, there are some marine reptiles today, but they are very few ... pretty much limited to the marine iguana and sea snakes ... all marine reptiles would also have lungs ... extinct or not ... and don't forget ... people are classified by the secular taxonomy as mammals ... but not because we are the same as monkeys ... it is merely because we have nails instead of claws like they do, and opposable thumbs like they do ... but we ... don't have them on our feet! Keep thinking, DrJ
