Fossil record shows a progression of organisms from simple to complex forms over time. Comparative anatomy reveals similarities in bone structure and development between different species, indicating a common evolutionary ancestry. Genetic similarity and shared sequences in DNA among different species provide strong evidence for common ancestry and evolution.
Though the forelimb of your cat or dog does not look much like your arms these are homologous structures that are almost identical bone for bone. This shows the common ancestry of all tetrapods and the closer common ancestry of you and your mammal pets.
The wings of birds and bees are an example of analogous features, as they have evolved independently in each group and do not share a common ancestry that possessed wings. Homologous features are those that are inherited from a common ancestor and are usually more similar in structure.
Fossil evidence
The comparisons between the anatomies of various organisms show common ancestry which supports evolution.
Examples of structures in different organisms that share a common ancestry include the pentadactyl limb in vertebrates (including humans, cats, bats, and whales) and the similar bone structure seen in bird wings, bat wings, and pterosaur wings due to a common ancestor from which they evolved. Another example is the vertebrate eye structure found in humans, birds, and octopuses, which have evolved independently yet share common features due to their shared ancestry.

Oh honey, it's like asking if the chicken or the egg came first! Both structure and function play a role in understanding the relationship between organisms. Structure gives you the blueprint, while function shows you how that blueprint is being used. It's a package deal, you can't have one without the other, darling.
how can you relate the structures of a chicken wings and the human arm adapted to served different function ignore that first answer because it makes no sense.some similarities are: 1)both of them have elbows 2)both have epithelial,connective,muscle,and nervous tissue
While there is no one common ancestry, many of them have Irish ancestry.
Homologies, similarities in structure or genetic sequence among different species, can reveal common ancestry and evolutionary relationships. Studying homologies can help us trace the evolutionary history of organisms and understand how they have diversified over time. By comparing homologous traits, scientists can infer the shared ancestry and evolutionary pathways of organisms.
The strong evidence for the common ancestry of all vertebrates is THE SIMILARITY OF THEIR EMBRYOLOGICAL STAGES.

Fossil record: Shows a gradual change in species over time, supporting the idea of common ancestry and evolution. Genetic evidence: Similarities in DNA sequences between different species indicate shared ancestry and evolutionary relationships. Comparative anatomy: Homologous structures among different species suggest a common origin and evolution from a common ancestor.
Common ancestry refers to the shared biological heritage between two or more species, indicating that they all descend from a common ancestor. For example, scientists study common ancestry to understand the evolutionary relationships between different species and trace their evolutionary history.
A purebred horse with the paper work that shows his ancestry.
