evolved from a common ancestor that also had the structure bg
Scientists infer that the similarities between the structures of seals and birds, such as their streamlined bodies and flippers or wings, suggest a case of convergent evolution. This means that despite their different evolutionary backgrounds, both animals have adapted to similar environmental challenges—namely, living in aquatic or aerial environments. These adaptations enhance their ability to move efficiently in water or air, demonstrating how similar ecological niches can lead to analogous physical traits in unrelated species.
Comparative anatomy is the investigation and comparison of the structures of different animals. Scientists use comparative anatomy to study the difference between species and how they are alike in other ways. By comparing the similarities and differences between a number of species, scientists can then construct a picture of their evolutionary relationships.
They all have tails and slits. (Not really sure i just got this from my homework.)
scientist have been able to infer the relationships between the major groups of vertebrates by bones
They all can carry the same type of dissese
Scientists use structural similarities, such as homologous structures and similar biochemical pathways, to determine evolutionary relationships. These similarities suggest a common ancestry and can help scientists infer how different species are related to each other. By comparing the presence and arrangement of these structures among different species, scientists can construct evolutionary trees to understand the history of life on Earth.
Embryology, along with similar structures like homologous organs and vestigial organs, provides clues about the evolutionary relationships between organisms. By studying the similarities and differences in embryonic development and structures across different species, scientists can infer how they are related and classify them into different groups based on their evolutionary history.
The structures of macro-molecules, such as DNA and proteins, can be used to infer relatedness between species because they are inherited from common ancestors. By comparing the similarities and differences in the sequences of these molecules among different species, scientists can construct phylogenetic trees that show the evolutionary relationships between them. Closer related species tend to have more similar macro-molecular structures than distantly related species.

Homologous structures are anatomical similarities in different species that suggest a common evolutionary ancestry. Similar structures in organisms that share a common ancestor are expected to be derived from that common ancestor. By studying these homologous structures, scientists can infer evolutionary relatedness and reconstruct the evolutionary history of species.

The practical result of using DNA sequence similarities in phylogenetic trees is the ability to infer evolutionary relationships between different species. By comparing DNA sequences, scientists can determine how closely related species are and reconstruct the evolutionary history of organisms. This helps in understanding the diversity and origins of life on Earth.
Embryonic structures can provide insights into the shared ancestry of species because they show similarities during development that may not be apparent in adult forms. Comparing embryonic structures across different species can help scientists infer evolutionary relationships and understand how different organisms are related. This can offer valuable information about the evolutionary history and relatedness of species.
Scientists use differences and similarities in characteristics such as anatomical structures, DNA sequences, and behaviors to identify and classify different life forms. By comparing these traits across organisms, scientists can determine how closely related different species are and infer their evolutionary history. This information helps scientists understand the diversity of life on Earth and how species are related to one another.
Anatomical similarities among different species provide evidence of evolution through the presence of homologous structures, which are structures that have a common evolutionary origin. These similarities suggest that different species share a common ancestor and have evolved from it over time, resulting in variations in the form and function of these structures. By comparing anatomical features across species, scientists can infer evolutionary relationships and trace the evolutionary history of organisms.
They look similar at birth
Scientists can infer that the two structures may have a common evolutionary origin or shared biological function due to their similarities. This can provide insights into the relationship between the two structures and potentially help to understand their roles in biological processes. Comparing the structures can also help in identifying conserved features that are important for their function.
