Answer
The correct answer is 'homologous structures'.
Explanation
## Step 1The problem provides a description of a comparison between the forelimbs of several species. The structures are very similar and share the same bones, although the species themselves are very different.## Step 2The four options provided are homologous structures, vestigial structures, fossilization, and analogous structures.## Step 3We need to understand the definitions of these terms to solve this problem. ### **Homologous structures** are anatomical features in different species that are similar because they were inherited from a common ancestor. These structures may serve different functions in the present-day species, but they have a similar underlying structure.### **Vestigial structures** are remnants of organs or structures that had a function in an early ancestor.### **Fossilization** is the process by which the remains or traces of organisms from the past are preserved.### **Analogous structures** are anatomical features in different species that are similar because they serve a similar function, but they were not inherited from a common ancestor.## Step 4Based on the definitions, the structures described in the problem are homologous structures. They are very similar and share the same bones, which indicates that they were inherited from a common ancestor.
