A real scientist who writes about creationists except he always calls them idiots.


Please see How IDiots Would Activate the GULOP Pseudogene.

The enzyme L-glucono-γ-lactone oxidase is required for the synthesis of vitamin C. Humans cannot make this enzyme because the gene for this enzyme is defective [see Human GULOP Pseudogene]. The GenBank entry for this pseudogene is GeneID=2989. GULOP is located on chromosome 8 at p21.1 in a region that is rich in genes.

Why is the gene for the synthesis of vitamin C defective in human apes? It's because our ancient ape ancestors lived in an environment where there was plenty of fruit to eat. So when mutations made this gene defective that was no problem. The creature didn't die because it could get vitamin C from its diet. Natural selection did not have to select for this gene being functional.

This is another example of millions of examples for why nothing in biology makes sense except in the light of evolution.

The blog is called Sandwalk. It is one of the best science blogs on the internet and it's many times more interesting than this blog.
