WebJun 11, 2024 · Cladistics is a biological classification system based on analysis of traits, genetic makeup or physiology that were shared with a common ancestor until some type of divergence occurred, producing new species. German taxonomist Willi Hennig jumpstarted cladistic classification in 1950 when he wrote his book on phylogenetic systematics.

WebFor groups A and B and C, trait “a” is a shared, derived trait: therefore in terms of “a”, A and B and C form a clade. If you had a branch C* coming off on the same family as F and G, then C and c* would be examples of parallel or convergent evolution. They possess the same trait (c and c*), but that trait arose independently, WebMar 28, 2024 · In biology, a trait that arose in an ancestor and is passed along to its descendants is referred to as a a)taxonomic group b)physical similarity c)molecular clock d)derived character See answers Advertisement Advertisement davidanaya111 davidanaya111 The correct answer would be D.
Webthese species last shared a common ancestor. One profound implication of this way of thinking about trait evolution is the idea that living species are the summation of their evolutionary history. In other words, if you list all the traits of a living species, you can assume that each trait arose on an ancestral branch somewhere in that species ...
