One gene, many mutations

past, but we only have data from the present to study it," she said. "This ability to go back in time and reconstruct an evolutionary path is very exciting, and I think this data set is uniquely suited for this type of time travel."

Taking the time to understand not only which genes are involved, but which specific mutations may be driving natural selection, Hoekstra said, can give researchers a much fuller picture of not only the molecular mechanisms by which mutations alter traits, but also the evolutionary history of an organism as well.

"By doing this we've discovered all kinds of new things," she said. "While we often think about changes happening in the entire genome, our results suggest that even within a very basic unit the gene we can see evidence for evolutionary fine-tuning."
