he doesn;t believe it's evidnece of protzoa to people evolution, a made up term, a made up argument. Also, sickle cell anemia is simply a mutation in RBC's that makes malaria difficult to infect the host. Are you suggesting that this painful disease, that some people get who aren't even in danger of malaria was planned? to me pain, death etc from teh disease seems like a shitty trade in for avoiding infection. God works in mysterious ways? or it's a fucking mutation and the outcome to the person is irrelevant?
it appears you dont understand the theory of evolution. let me explain it to you
primordial soup -> bacteria/protozoa -> photosynthetic sea plants -> sponges -> starfish -> seahorse-> lobsters and fishes -> fishes that walk on the shore -> lizards that live near the shore -> foxes -> apes -> humans
now, the exact species between each supposed level of evolution could be different, but thats the theory "protozoa to people"
if you read his articles on the site you will see that he explains that malaria to sickle cell is in no way evidence of the types of changes needed for evolution to occur
God did not want for us to sin, but because we did we now live in a world cursed by sin, held together only for a time by Gods great love, until he restores it back to perfection. Sickle cell was not planned, it is a result of our own sinfulness, and God loves us so much that he came down from heaven and submitted to torture and crucifixion in order to save us from diseases like it.
