Convergent evolution would be the best way to explain why two species that look similar are not necessarily that closely related. In convergent evolution, distinct species develop similar anatomical characteristics after its divergence from one common ancestor that does not possess the initial characteristic.
Answer:
C. If spiders evolved first, six legs is the derived trait.
Explanation:
A derived trait is a characteristic that is <u>present in a species but was absent in the common ancestor of this species.</u>
Spiders evolved from a crab-like ancestor and, although crabs are decapods, they possess eight walking legs and two claws. As insects evolved after spiders, the 'new' or derived trait that was absent in the ancestor would be having <u>six legs</u>.
Therefore, in this scenario, Mr. Morales states that <u>spiders evolved before insects</u>, which indicates that <u>the trait of six legs is a derived trait</u> from the last common ancestor, a characteristic that separates arachnids from insects.
