Day 5: Water creatures and birds

Notice sea creatures are described as having more than one kind, as also the birds. We see this in that both air-breathing mammals such as whales and dolphins share the sea with water-breathing fish. The kinds of birds, since they are described as “winged” rather than “feathered”, could include both birds and bats. Other “short-flying” creatures such as some species of fish and squirrels apparently aren’t included since their flights, of short duration and always close to the ground, don’t occur “in the firmament/expanse” as indicated in Gen 1.20.

Because there are “kinds” of sea creatures, we would never expect to find evidence of perch evolving into grouper, or dolphins evolving into whales, etc. Similarly we would not expect to find evidence of sparrows evolving into eagles, or hummingbirds evolving into storks, etc. These expectations are borne out by physical evidence. “Micro-evolution” is seen as creatures within the constraints of their “kind” evolve to accommodate survival pressures; but “macro-evolution” where a creature of one “kind” evolves into another “kind” is never seen in the physical evidence.
