1 The opossum , which is native to North America, and the kangaroo , which is native to Australia, are marsupials.

A belong to the same species B must range great distances to eat C have very similar skeletal structures D are descended from a common ancestor

Answer 1

The question relates these two marsupials based on their shared characteristic: they both carry their immature offspring in a pouch. Each answer choice attempts to explain this common feature: Option A suggests that they belong to the same species. However, opossums and kangaroos show distinct differences, indicating that they are distinct species. Option B suggests they cover great distances to eat. But their diet range is irrelevant in explaining their pouch characteristic. Option C posits that their skeletal structures are parallel. This may not necessarily be true, because different marsupial species often show significant varying skeletal structures. Option D speculates that they are descendants from a common ancestor. According to evolutionary theories, related species sharing unique physical traits have likely evolved from a common ancestor. Certainly being vertebrates, and the fact they're marsupials suggests that opossum and kangaroo likely evolved from a common progenitor. The answer, therefore, stems from understanding how evolutionary history can impact present day features in species.
