Question

organisms can be organized by their similarities and differences. the incomplete cladogram shows the relationship between some invertebrates based on their body structures. use the drop - down menus to construct an argument about the development of six legs in invertebrates, based on the body structures shown. the development of six legs should be placed at letter e on the cladogram because the body structure is present only in organisms that point on the cladogram.

Explanation:

A cladogram shows evolutionary relationships. Six - legged organisms (ants, crickets, flies, dragonflies) share a common trait. The point (E) on the cladogram is where this trait (six legs) first appears. Organisms after this point (E) have six legs, while those before (like worms and spiders) do not.

Answer:

after
