Three organisms have four shared characteristics. they all have a backbone and scales, lay eggs, and walk on land. what can be determined based on this information alone? they are members of different species. they are members of the same species. their common ancestor has the same four shared characteristics. their common ancestor has none of the shared characteristics. quickly

Ans.

Features shared by different organisms are inherited from a common ancestor. A common ancestor of any group of organism is defined as the most recent organism, from which all the individuals are descended directly.

As all four organisms have scales and a backbone, lay eggs, and can walk on land, all these characteristics should be present in their common ancestor, from which they arose.

Thus, the correct answer is 'option). their common ancestor has the same four shared characteristics.'

their common ancestor has the same four shared characteristics.'
