Since the fossil record is not solely used to support evolution, its acceptability still stays as there are adequate reasons for the incomplete fossil record. The fact is that conditions need to be perfect for the fossilisation to occur. Many factors can affect whether an organism will fossilise. The fossil record lacks many soft-bodied organisms since they decompose too quickly. Dead organisms can be eaten quickly by others at the time. The fossil record contains many hard-bodied aquatic organisms as they can be easily covered in layers of sediment and away from scavengers. While these reasons are valid, the fact of the matter is that only a small percentage of fossil have been …show more content…
It serves as evidence for evolution as it helps illustrate the fact that a variety of organisms share a common ancestor. There are many examples of similar structural features among organisms but they can generally be divided into one of two groups: homologous and analogous traits. Homologous structures are similar in basal design, but vary in function due to different environmental conditions or ways of life and are examples of adaptive radiation. When organisms share an analogous trait, it means that they have similar structures or physiological processes that perform the same function but have no close phylogenetic
