What is a synapomorphy? correct answers A trait that is similar in two or more species because it is derived from a trait that existed in a common ancestor. Why do synapomorphies arise during evolution? correct answers When a new species begins evolving independently, novel traits arise which are then passed on to its descendant species. What does it mean to say that one phylogenetic tree is more parsimonious than another? correct answers Fewer changes have to occur to make the origin of t...
