It is true that scientists determine evolutionary relationships by looking at breeding behavior, geological distribution, and structural similarities between organisms. Scientists can use other criteria to determine evolutionary relationships.
scientists can infer how closely related the organisms are in an evolutionary sense
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.
To build a cladogram showing evolutionary relationships among species, scientists can analyze morphological traits (physical characteristics) and genetic data. By comparing similarities and differences in these traits and genetic sequences, scientists can determine how closely related species are and create a visual representation of their evolutionary history.
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 rely primarily on genetic data, particularly DNA sequences, to determine evolutionary history. By comparing the genetic similarities and differences between different species, scientists can infer relationships and construct evolutionary trees. This approach is known as molecular phylogenetics.

DNA is often studied to find out about evolutionary relationships. By comparing the similarities and differences in the genetic material (DNA sequences) of different species, scientists can infer their evolutionary relationships and construct evolutionary trees. This field of study is known as molecular phylogenetics.

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 use a taxonomic map to help classify organisms. The placement of organisms on this was originally based on similarities between species. Today we are able to look at their actual genes, which has resulted in a better understanding of evolutionary relationships - or the lack of them- and has resulted in some re-classification.
Anatomy and physiology are important in determining evolutionary relationships between animal phyla. Similarities and differences in these traits can provide insights into common ancestry and evolutionary history. By studying the anatomical and physiological characteristics of different animal groups, scientists can infer relationships and construct evolutionary trees to understand the evolutionary links between phyla.

When constructing patterns of evolutionary relationships using molecular phylogenetics, researchers typically compare DNA, RNA, or protein sequences from different organisms. By analyzing similarities and differences in these molecular sequences, scientists can infer evolutionary relationships and determine how closely related different species are. This comparison allows for the construction of phylogenetic trees that visualize these relationships over evolutionary time.

Cladograms are diagrams that show the evolutionary relationships among species based on shared characteristics. They use branching patterns to illustrate how species are related to each other through common ancestors. By analyzing the similarities and differences in traits, scientists can construct cladograms to depict the evolutionary history of different species.
By comparing body structures of living organisms...By studying fossils...And comparing the early development of different organisms.
