mr. morales is teaching a lesson on classification. he says that spiders are classified as a different group than insects because they have eight legs instead of six legs. he explains that spiders evolved first. mr. morales also says that having eight legs is the derived trait that separates the two groups. antonio thinks mr. morales is wrong. which piece of information is antonio considering?\nspiders do not have eight legs.\ninsects do not have six legs.\nif spiders evolved first, six legs is the derived trait.\nspiders do not have derived traits, since they evolved first.

Answer

Answer:

C. If spiders evolved first, six legs is the derived trait.

Brief Explanations:

A derived trait is a trait that is present in a species but was not present in the common ancestor of a group. If spiders (with eight legs) evolved first, then the six - legged condition in insects would be the new (derived) trait that evolved after the split from the common ancestor. Spiders do have eight legs (so option A is wrong), insects do have six legs (so option B is wrong), and all organisms have derived traits as evolution is an ongoing process (so option D is wrong).
