You and your friend, inspect a group of fossils from different organisms with various features. Your friend is convinced that all of the fossils are unrelated that you find evidence that these organisms share an ancestor what is an example of evidence that you could use to support this argument, would it be number of bones? Heights tooth features are patterns and lamb structures
While the number of bones, heights, tooth features, and limb structures could provide clues about the similarities or differences among fossils, they might not be sufficient evidence to support the argument that these organisms share a common ancestor. Here are a few examples of evidence that could potentially support the argument:
1. Comparative Anatomy: If the fossils exhibit similar anatomical structures, such as the presence of specific bones, muscles, or organs, it suggests a shared ancestry. This similarity is especially compelling if the structures serve the same functions across different organisms.
2. Transitional Fossils: Finding fossils that possess both ancestral and derived characteristics can indicate a transitional stage in the evolution of a particular lineage. These fossils provide evidence of evolutionary links between different organisms and the common ancestor they share.
3. Genetic Similarities: Genetic studies can reveal shared DNA sequences or genetic traits among different organisms. If the fossils under inspection belong to species with genetic similarities, it implies a shared evolutionary history.
4. Biogeographical Patterns: Observing patterns in the distribution of fossils in different geographical regions can also provide evidence of common ancestry. For instance, if fossils of similar organisms are found in geographically separated areas, it implies a connection between those regions and a shared evolutionary origin.
5. Developmental Similarities: Comparing the embryonic development of different organisms can reveal similarities and shared developmental processes. If the fossils exhibit similar patterns of development, it suggests a common ancestry.
It is important to note that evidence from multiple lines of inquiry, such as those mentioned above, is usually needed to develop a more robust argument for a shared ancestor.
