Answer:
D. Fossils of species that no longer exist but are ancestors of current species have been found in rock layers
Step-by-step explanation:
As you may already know, evolution is the term that refers to the changes in hereditary characteristics that have been caused among living beings from generation to generation. In the case of evolution by natural selection, we can say that it represents the passage of advantageous characteristics to the environment that have been passed between living beings through the generations.
This type of evolution is easily confirmed by the presence of fossils of the most diverse species of living beings in the world. This is because, as we know, fossils are records of species that do not currently exist, but existed millions of years ago and are similar to current species, being their ancestors.
