Animal life has evolved in hundreds of millions of years on Earth. Some scientists claim that changing environmental conditions, like the accumulation of dissolved oxygen and ocean minerals or increased atmospheric oxygen, eventually allowed higher metabolic rates and increased animal activity. Others suggest that with the development of sophisticated locomotor skills, a wide range of predators and prey evolved, leading to an evolution.

Expert Solution & Answer

Answer to Problem 1TY

The correct answer is option (e)bilateria, protostomia, ecdysozoa.

Explanation of Solution

Explanation/justification for the correct answer:

Option (e) Bilateria, Protostomia, Ecdysozoa.The correct hierarchy of divisions in the animal kingdom from most inclusive to least inclusive is Bilateria, Protostomia, Ecdysozoa. All animals are believed to be derived from a choanoflagellate-like ancestor. An animal categorized based on body plans and molecular data. So, the correct answer is option (e).

Explanation for incorrect answer:

Option (a)Deuterostomia, Protostomia, Ecdysozoa. The correct hierarchy of divisions in the animal kingdom from most inclusive to least inclusive is Bilateria, Protostomia, Ecdysozoa. All animals are believed to be derived from a choanoflagellate-like ancestor. An animal categorized based on body plans and molecular data. Thus, from most inclusive and least inclusive Deuterostomia, Protostomia, Ecdysozoa is not the correct hierarchy of divisions in the animal kingdom. So, this is an incorrect option.

Option (b) Bilateria, Lophotrochozoa, Deuterostomia.The correct hierarchy of divisions in the animal kingdom from most inclusive to least inclusive is Bilateria, Protostomia, Ecdysozoa. All animals are believed to be derived from a choanoflagellate-like ancestor. An animal is categorized based on body plans and molecular data. Thus, from most inclusive and least inclusive, Bilateria, Lophotrochozoa, Deuterostomia is not the correct hierarchy of divisions in the animal kingdom. So, this is an incorrect option.

Option (c)Bilateria, Ecdysozoa, Protostomia.The correct hierarchy of divisions in the animal kingdom, from most inclusive to least inclusive is Bilateria, Protostomia, Ecdysozoa. All animals are believed to be derived from a choanoflagellate-like ancestor. An animal categorized based on body plans and molecular data. Thus, from most inclusive and least inclusive, Bilateria, Ecdysozoa, Protostomiais not the correct hierarchy of divisions in the animal kingdom. So, this is an incorrect option.

Option (d)Deuterostomia, Ecdysozoa, Bilateria.The correct hierarchy of divisions in the animal kingdom, from most inclusive to least inclusive is Bilateria, Protostomia, Ecdysozoa. All animals are believed to be derived from a choanoflagellate-like ancestor. An animal categorized based on body plans and molecular data. Thus, from most inclusive and least inclusive, Deuterostomia, Ecdysozoa, Bilateriais not the correct hierarchy of divisions in the animal kingdom. So, this is an incorrect option.
