Biology called. It has not changed its position. Two chromosomes. Two options. Settled science from the moment it actually was settled science. This shirt is for the person who finds it deeply ironic that the side claiming to follow the science stopped doing exactly that the moment it became inconvenient. Clean, bold, and science backed which makes it the hardest shirt on the internet to argue with. Wear it confidently because the data is on your side. Makes a great gift for doctors, nurses, biology teachers, and anyone else who took a basic science class and retained the information. Iron Soil Co.
