Biologists are puzzling over several species of green-blooded lizards in New Guinea. This fascinating color comes from green pigment found in bile, a normally toxic compound produced by the liver to break down fats. The level in their bloodstream is 40 times what a human could tolerate, but the lizards are doing just fine.
Most lizards’ blood is red like ours, including the dozens of other lizard species on the island. So evolutionists have long assumed the quirky green blood came via mutations in a single population. But after comparing the DNA of many species of New Guinea lizards, researchers found that lizards with this improbable blood color arose in four separate red-blooded populations, not from one. So they are forced to conclude that green blood evolved on four separate occasions in the island’s history!
It’s hard enough to imagine how this could happen once from random mutation. They still don’t know. And they don’t even know what advantage green blood gives the creatures (although they have a few hypotheses). But since it evolved independently four times, they say, it must be beneficial. It’s only logical.
Or could it be that an omnipotent Creator designed them to live long with green blood and prosper in the environment where they live?
