_ provides a visual record in a complete series showing the evolution of an organism?

Explanation

Paleontology is the study of fossils, which serve as a visual record illustrating the evolution of organisms over time. The fossil record is made up of the remains or traces of organisms that have been preserved in sedimentary rocks throughout geological history. It provides insight into the characteristics and forms of ancient species at specific points in time and may also show transitions between different species or groups, offering strong evidence for the process of evolution. Unlike paleontology, molecular biology, biogeography, and biochemistry do not provide visual records of evolutionary history, which makes them less relevant for understanding these changes.
