12 pagesGene Flow and Ancient DNA: Trees with Connecting Branches
- Marianne Sommer (author)
Mainly, however, while admixture between modern human populations had always somehow been granted and gene flow between modern and archaic populations had not entirely been ruled out, trees were what was being built in human population genetics. The accessibility of ancient DNA (aDNA) in quality, quantity, and increasing time-depth initiated the emergence of aDNA population genomics, and, with this, revolutionary insights like modern-human–Neanderthal interbreeding made news. In spite of this, aDNA studies did not really overthrow the tree diagram. Even while gene flow was often assumed to have taken place over long periods of time, the core diagram of evolution simply acquired a few connecting arrows between branches.

(author)Marianne Sommer holds the chair of Kulturwissenschaften at the Department for Cultural and Science Studies at the University of Lucerne, Switzerland. Prior to that, she has held postdoctoral positions and professorships at the Max Planck Institute for the History of Science in Berlin, Pennsylvania State University, the ETH Zurich and University of Zurich, and has been a guest at many institutions, including Stanford University. For her research in the history of earth, life, and human sciences, encompassing processes of narration, visualization, and exhibition, she has received the Swiss National Latsis Prize. Her monograph History Within (published with The University of Chicago Press in 2016) engages with the science, politics, and culture related to reconstructions of human evolutionary histories; it traces the generation and circulation of such knowledge from the late nineteenth century to the present, including through venues like the museum, the zoo, literature, or the web. Among her monographs are also Bones and Ochre: The Curious Afterlife of the Red Lady of Paviland (published with Harvard University Press in 2007) and Evolutionäre Anthropologie (published with Junius in 2015). Bones and Ochre tells the scientific and cultural history of paleoanthropology and to a lesser degree archeology through the ‘biography’ of the most likely first fossil human skeleton discovered in 1823. Evolutionäre Anthropologie is an introduction to the history of evolutionary anthropology for scholars, students, and the interested public.
