The similarities between the whale fossils demonstrate that such fossils have similar body structures with identical curved backs, morphology, and body patterns. This similarity among the whale fossils resembles closely one another.
Fossils may be defined as dead and organic remain of past living organisms that were buried deep into the soil millions of years ago. The age of fossils is significantly estimated by the analysis of sedimentary rocks.
The differences among the whale fossils are illustrated by the appearance of their feet to withstand adverse conditions. The difference is also observed in the long heads, sharp teeth, external skin, etc. The difference in whale fossils developed due to their adaptations and survival efficiency.
Both the similarities and differences between the whale fossils are characterized on the basis of their general characteristics like adaptations, nutrition, cellular processes, etc.
Therefore, the similarities between the whale fossils demonstrate that such fossils have similar body structures with identical curved backs, morphology, and body patterns.
