Could Designed Systems Explain Green Lizard Blood?

Green blood is not something you see every day. The recent search for why several species of lizards found in New Guinea have green blood assumes an evolutionary origin for these creatures. It seems like the researchers started with a discovery that indicates green blood developed independently in four species from red-blooded ancestors.

What about the green tinted hemoglobin based blood of lizards with high concentrations of biliverdin, a toxic green bile pigment? For the lizard, it’s like having the jaundice yellow tint in a mammal due to bilirubin, only without the dire consequences of liver failure. The lizard biology does it on purpose, for a reason unknown for now.
Lobsters have actual blue blood based on hemocyanin which is formed of copper compounds. Depleted of oxygen it’s clear, and oxygenated it’s blue tinted. On the dining plate, the residue is a white clumpy material.
“Lobsters have actual blue blood....”
Hmmm, I always thought blue blood was ‘cuz of RINO GOPee elite Bush family connections.....
Squashed Grasshoppers have green blood.
Copper instead of iron in the blood cells?
Some octopi have blue blood because they use copper-based hemocyanin to bind to oxygen rather than iron-based hemoglobin. Hemocyanin releases its oxygen more readily in extreme cold than hemoglobin does.
Some species of icefish have clear blood because it has no oxygen transporting medium at all.
New Guinea’s skinks have red blood but they don’t excrete the yellow-colored biliverdin produced by their liver. Humans do excrete biliverdin, and the levels it builds up to in skink would kill a human. But in the skink, all it does as color their blood green.
"We use phylogenomic data from thousands of genome-wide loci to establish a robust phylogeny for Prasinohaema and related Australasian lizards with normal blood to determine the evolutionary history of green blood. Our phylogenetic and ancestral character state reconstruction results produce a highly robust phylogeny that supports four independent origins of green blood, demonstrating surprising evolutionary dynamism of green blood."
Later, they summarize this conclusion as strong support for four separate origins of green blood.
If true, this is an interesting finding but still counterintuitive from established views guided by current evolutionary theory as the researchers themselves acknowledge, Considering the pathological consequences of elevated concentrations of bile pigments in most animals, green blood was assumed to have originated only once in amniotes.
Also, given evolutionary theorys insistence on the random nature of genetic variation and the purposeless characterization of nature somehow favoring or punishing any individual organism in the selection process, how likely is it that green blood would emerge independently four times? The probability of that happening is even murkier since the authors admit, How cytotoxicity of bile pigments might be selected for is unclear.
So much for Occam's Razor!
He be f***in' them GREEN bitches!
