So to those creationists who reject evolution and insist that an understanding of evolution isn’t crucial to the practice of medicine, this one’s for you:
HIV is evolving rapidly to escape the human immune system, an international study led by Oxford University has shown. The findings, published in Nature, demonstrate the challenge involved in developing a vaccine for HIV that keeps pace with the changing nature of the virus.
. . .
‘Even in the short time that HIV has been in the human population, it is doing an effective job of evading our best efforts at natural immune control of the virus. This is high-speed evolution that we’re seeing in the space of just a couple of decades.’
This is just another reason why you should never let a creationist doctor treat you.
