Hemaglobin – No Traceable Evolutionary History!! (in other words: Evidence Against Evolution)
“Consider hemoglobin, for example, the protein that carries oxygen in red blood cells. Dickerson says that hemoglobins pose “a puzzling problem. Hemoglobins occur sporadically among the invertebrate phyla [the animals without backbones] in no obvious pattern.” That is, they don’t occur in an evolutionary branching pattern. I would suggest that they do occur in a creationist mosaic or modular pattern, like bits of blue-colored stone in an artist’s mosaic. We find hemoglobin in nearly all vertebrates, but we also find it in some annelids (the earthworm group), some echinoderms (the starfish group), some mollusks (the clam group), some arthropods (the insect group), and even in some bacteria! In all these cases, we find the same kind of molecule—complete and fully functional. As Dickerson observes, “It is hard to see a common line of descent snaking in so unsystematic a way through so many different phyla. . . .”
If evolution were true, we ought to be able to trace how hemoglobin evolved. But we can’t. Could it be repeated evolution, the spontaneous appearance of hemoglobin in all these different groups independently, asks Dickerson? He answers that repeated evolution seemed plausible only as long as hemoglobin was considered just red stuff that held oxygen. It does not seem possible, he says, that the entire eight-helix folded pattern appeared repeatedly by time and chance. As far as creationists are concerned, hemoglobin occurs, complete and fully functional, wherever it is appropriate in the Creator’s plan, somewhat like a blue-colored tile in an artist’s mosaic.”
