Firstly and most importantly it is the fact that the anatomies of all life follow a pattern of nested hierarchies. More recognisably, we often find atavistic structures that have diminished function in modern lifeforms, but not in sister clades or in more basal (and possibly extinct) lifeforms.
Slight anatomical changes over significant amounts of time resulting in new species and adaptations is precisely what evolution is. Having a knowledge of certain anatomies allows for comparison. Take orangutan anatomy for example. It is extremely similar to human anatomy, but there are certain differences that tell us that humans are not descendants from orangutans. Also, the fossil record on which evolution evidence is so well based, relies largely on classifying anatomical characteristics.
Anatomy is a useful tool in gaining evidence for evolution. The most useful thing is to examine homologous structures, ie anatomical similarities between different species. The best example of this is the pentadactyl limb. It is found in humans, dolphins and bats. This shows that at some point in the past there must have been a common ancestor from which these 3 diverse groups of animals evolved.
Because of the morphological homologies they display with similar structures in other extant and extinct lifeforms, following, like virtually every other morphological or anatomical feature of life, the nested hierarchies of biology.

Accept fossil evidence, anatomical evidence, molecular evidence
Fossil records, anatomical similarities among different species, and the observation of natural selection in action were some of the key pieces of evidence used to support the idea of evolution when it was first proposed.
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.
Homologous structures are evidence for evolution because they indicate that different species share a common evolutionary ancestor. These structures have similar underlying anatomical or genetic features, suggesting a shared evolutionary history. For example, the bones in the limbs of vertebrates all share a common anatomical structure, indicating a shared evolutionary origin.
The evidence from the fossil record is considered the strongest support for other forms of evidence in evolution. Fossils provide a physical record of past organisms, showing changes over time and the relationships between different species. This evidence complements genetic, anatomical, and embryological evidence to provide a comprehensive understanding of evolutionary processes.
Fossil record: The transition of species over time, as documented through fossils, provides indirect evidence of evolution and common ancestry. Comparative anatomy: Similarities in the anatomical structures of different species, such as the pentadactyl limb in vertebrates, suggest a shared evolutionary history.
Fossil records, anatomical similarities, embryological development, and genetic similarities are all forms of evidence that support the theory of evolution. These pieces of evidence show the gradual changes in species over time and provide support for the idea that all organisms are related through common ancestry.
Vestigial structures are remnants of features that were functional in the ancestors of a given species but are no longer useful in the current species. This supports the idea of evolution as it suggests that species have evolved over time from ancestors with different anatomical features. The presence of vestigial structures provides evidence of common ancestry and the gradual changes that have occurred over time through the process of evolution.
Similarities in DNA sequences, anatomical structures, and developmental pathways provide evidence of a common ancestry among organisms. Additionally, the study of fossils and transitional forms help support the idea of evolution and common ancestry.
