As biologists explore the variation across the genomes of living people, they’ve found evidence of evolution at work. Particular variants of genes increase or decrease in populations through time. Sometimes this happens by chance. Other times these changes in frequency result from the gene’s helping or hindering individuals’ survival.
Kathryn McGrath was awarded a Leakey Foundation Research Grant in our spring 2016 cycle for her project entitled “Understanding stress-related enamel defects in wild mountain gorillas.” Here she updates us on her progress.
