The most accurate evidence of an evolutionary relationship between two organisms is the presence of shared genetic similarities, specifically in their DNA sequences. This indicates a common ancestry and evolutionary history between the two organisms.
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 determine evolutionary relationships between animal phyla using evidence from comparative anatomy, fossil records, molecular genetics, and embryology. By studying similarities and differences in these aspects across different animal groups, researchers can infer how they are related to each other in the tree of life.
The term "missing link" is often used in evolutionary biology to refer to a hypothetical ancestral species that fills the gap between different evolutionary stages. It is commonly used to describe a transitional fossil that would provide evidence for the evolutionary relationship between two different species.
Molecular evidence refers to the use of genetic material such as DNA or proteins to understand evolutionary relationships between different species. By comparing molecular sequences, scientists can determine how closely related organisms are and study their genetic diversity and evolutionary history. This type of evidence is widely used in the field of molecular biology and genetics to gain insights into the evolutionary processes that have shaped life on Earth.

The number and structure of chromosomes help determine evolutionary relationships between species. Chromosome comparison helps to provide evidence of the relationships in a species.
Biochemical analysts use similarities in molecules like DNA, proteins, and enzymes as evidence for evolutionary relationships. The more similarities there are between the molecules of different organisms, the closer their evolutionary relationship is believed to be.
Anatomy and physiology are used, as they provide insights into the structural and functional adaptations of organisms, which can help determine evolutionary relationships between phyla. These aspects, along with molecular data and other evidence, are important for understanding the evolutionary history of different groups of organisms.

They show similarities between organisms structure. if the similarities are large then it shows that those organisms share a common ancestor.
Zygomycetes and ascomycetes are considered sister taxa within the fungal kingdom based on morphological evidence, such as the presence of nonseptate hyphae, asexual spores, and sexual spores enclosed in sac-like structures. This suggests a close evolutionary relationship between the two groups, possibly sharing a common ancestor in fungal evolution.

A branch on a phylogenetic tree indicates the evolutionary relationship between different species. The length of the branch represents the amount of evolutionary change that has occurred between the species, with shorter branches indicating a closer relationship and longer branches indicating a more distant relationship.
Whales and dolphins are believed to have evolved from artiodactyls. This is supported by genetic and anatomical evidence, showing a close evolutionary relationship between these groups.
