Solution: Animals do not share a common ancestor, even though they have a wide range of structures. This is because shared ancestry can severely limit diversity. Since many of the creatures share the same habitat, evolution through geographical isolation and speciation is unlikely. As a result, shared ancestry for all species is unlikely.
Does the occurrence of the diversity of animals on earth suggest their diverse ancestry also? Discuss this point in the light of evolution.
