This weeks interview is with Mark Jeffries, Director of Interdisciplinary Arts & Sciences at Dixie State University. Mark talks about the ghost ancestors that scientists are discovering as DNA testing becomes more prevalent.
The Denisovans or Denisova hominins are an extinct species or subspecies of archaic humans in the genus Homo. Pending its taxonomic status, it currently carries temporary species or subspecies names Homo denisova, Homo altaiensis, Homo sapiens denisova, or Homo sapiens Altai. In March 2010, scientists announced the discovery of an undated finger bone fragment of a juvenile female found in the Denisova Cave in the Altai Mountains in Siberia, a cave that has also been inhabited by Neanderthals and modern humans. The mitochondrial DNA (mtDNA) of the finger bone showed it to be genetically distinct from Neanderthals and modern humans. The nuclear genome from this specimen suggested that Denisovans shared a common origin with Neanderthals, that they ranged from Siberia to Southeast Asia, and that they lived among and interbred with the ancestors of some modern humans.
