The correct answer is B. The existence of homologous structures
Explanation:
The idea that life changes over time is related to the evolution of organisms, as is due to evolution, species do not remain the same bt change their features over time, and even new species appear. One of the main evidence for both evolution and the idea life changes is the existence of homologous structures that refer to structures such as bones or organs organisms of different species or types share and that show they had a common ancestor and due to changes in live new organisms appear. For example, humans, birds, horses, and cats have similar bones in their limbs which suggests all animals had the same ancestor but due to the way life changes, now they are completely separate species.
