1941 science test shows how things have changed... 1941 exam unearthed by one anatomy professor. The test is a relic of a simpler time that tells us a lot about the evolution of studying evolution. What makes the 1941 test a fossil in its own right is that it doesn't mention DNA, or molecular biology, in its questions about evolution, he adds. A June report in the Nature journal about a newly- discovered dinosaur fossil, for example, feeds the measurements of the 155-million-year-old creature into debate about the evolution of bird digits. But today, evolutionary biologists also have a great deal of information about the genes driving development of those digits, Holliday says, illuminating unexpected links between species and complicating the argument.
