On the third day, Finding Your Roots campers dig into their DNA test results to find out the likelihood they have various individual genetic traits. They take a PTC test to see if they have the dominant gene for tasting bitter compounds. Campers then head outside to play a survival game of genetic mutations and natural selection called "Food for the Bird Brain". In the final segment campers learn how ancestry, geography and natural selection combine to determine their skin color.
