BROKEN GENES. “Other historical markers can be found in our genes. We have a gene to make Vitamin C but, unfortunately for those sailors who died from scurvy, it is broken, so we have to get Vitamin C from our food. Chimpanzees and orangutans have the same broken gene, which can only have been inherited from our common ancestor for whom it was functional, as it still is for many animals.”
