Question

State one type of additional information that could be used to determine if these three species are closely related.

Answer 1

Study the bone structure of limbs.

Step-by-step explanation:

Study the bone structure of limbs can be used to find out the relatedness and relationship among three species because the pattern of bones structure is similar but the structure is different from one another due to different environmental conditions. This study provides important and useful information whether the three species are closely related or not. If they have similar bone structure than we can say that there are more chances that they are closely related to each other.
