Transitional fossils are specimens which have features of their ancestor species along with the species that descended from them. They offer us clues about how evolution occurred.

Finding out fossils aids them learn about when And exactly how unique species lived numerous many years back. Often, fossils explain to scientists how Earth has adjusted.
) is a well-known example of fossilization—items of tree trunks grow to be super-tough rocks, but nonetheless keep growth rings and also mobile buildings of the when-residing tree. Lucia RM Martino, NMNH
