In this episode, Ruby and Laura spoke to Bianca De Sanctis, a PhD student in Professor Eske Willerslev’s research group in the Department of Zoology at the University of Cambridge. Bianca's research focuses on genome reconstruction using ancient DNA samples to gain a snapshot of what ancient ecosystems looked like. Bianca fills us in on a recently published study where she and her colleagues reconstructed the genomes of a Stone Age American black bear and an extinct short-faced bear using environmental DNA samples from a remote cave in Mexico. She also discusses the difficulty of working with ancient DNA samples, and how the use of ancient environmental DNA samples has provided a huge leap forward in the world of ancient genomics.
