Testing cyclostome-based models for vertebrate ancestry
Meeting Abstract 24-4 Thursday, Jan. 4 10:45 – 11:00 Testing cyclostome-based models for vertebrate ancestry MIYASHITA, T*; PALMER, AR; University of Alberta; University of Alberta tetsuto@ualberta.ca As the only living jawless vertebrates, cyclostomes (hagfish and lampreys) are a crucial taxon to infer conditions at the crown vertebrate node. The Hagfish Model accepts hagfish as nesting outside other […]
