To determine which organ systems evolved after Protostomes and Deuterostomes diverged from other animals, we can look at the characteristics of these two groups and compare them to other animal groups.
Protostomes and Deuterostomes are two major groups of animals that diverged early in evolutionary history. Protostomes include animals like insects, mollusks, and annelids, while Deuterostomes include animals like vertebrates and echinoderms.
1. Nervous system: The nervous system is present in both Protostomes and Deuterostomes, so it did not evolve after their divergence.
2. Reproductive system: The reproductive system is also present in both Protostomes and Deuterostomes, so it did not evolve after their divergence.
3. Respiratory system: In terms of respiration, Protostomes and Deuterostomes have different strategies. Protostomes typically rely on simple respiratory structures like gills or tracheae, while Deuterostomes often have more complex respiratory systems such as lungs or gills. However, both groups have evolved these respiratory systems independently, so the respiratory system is not a distinguishing factor that evolved after their divergence.
4. Digestive system: Both Protostomes and Deuterostomes have a complete digestive system, meaning they have a mouth and an anus. This suggests that the digestive system was already established at the time of their divergence.
5. Cardiovascular system: The cardiovascular system, which includes the heart and blood vessels, is more developed and specialized in Deuterostomes, particularly in vertebrates. While Protostomes also have circulatory systems, they are generally less complex. Therefore, the cardiovascular system is one of the organ systems that evolved after Protostomes and Deuterostomes diverged from other animals.
In conclusion, the organ systems that evolved after the divergence of Protostomes and Deuterostomes from other animals are the respiratory system and cardiovascular system.
