Question

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? spiders do not have eight legs. insects do not have six legs. if spiders evolved first, six legs is the derived trait. spiders do not have derived traits, since they evolved first.

Explanation:

In evolutionary biology, if a group is said to have evolved first, the traits of the later - evolving group are the derived traits. If spiders evolved first, then the six - legged trait of insects would be the derived trait, not the eight - legged trait of spiders as Mr. Morales claims.

Answer:

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