Answer:
The answer is a. homologous structures
Explanation:
Homologous Structures:
Structures that have<u> similar anatomy or similar structure</u> but have different functions are called homologous structures.
These structures indicate shared ancestry between the animals in question. This means that the structures may be used for different functions but they are encoded by same or similar genes.
The bones in the picture perform quite different functions and they might look different from the outside but as we look closer, the bone structure and joints are similar. This shows that all of these animals evolved from a common ancestor.
According to studies, 80% of the data that we take in comes from our power of sight. Sight lets us take in 180° of images, perceive 1 million different colors, adjust what we see based on level of light & focus close up or miles away. Our vision is more detailed than any digital camera.
