Analogous structures are evidence of convergent evolution, where unrelated species evolve similar traits independently in response to similar environmental pressures. This supports the idea that evolution can lead to similar solutions to maximize survival and reproductive success in different lineages.
Comparative DNA samples from chimpanzees and humans show very well the concept of evolutionary common ancestry. Aside from that, the differences in DNA among organisms, especially at certain loci, show how long two, or more, organisms shared common ancestry.
DNA (Deoxyribonucleic acid) is the genetic material because it contains the code for the entire organism. It's sort like an equation from which an entire organism with all it's unique differences can be created.
The discovery of DNA and the ability to study genetic sequences have provided strong evidence supporting evolution by showing similarities in DNA among different species, indicating a common ancestry. This molecular evidence was not available to Darwin and has since reinforced the theory of evolution.
Common ancestry. In this case the last universal common ancestor, LUCA.
The DNA genetic code provides the best evidence of the common ancestry of life. Science has shown that there are many similarities between DNA sequences.

Simularities in DNA sequence
Fossil evidence
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.
Actually, it is the strongest evidence for evolution. Without one fossil we would know from the DNA evidence that evolution has occurred and is occurring. It is in the DNA of organisms that we see the strongest evidence for common ancestry. The products of those genes are sometimes highly conserved down the ages. Ribosomes, the workbenches on which proteins are made, differ hardly at at between you and pets.
Simularities in DNA sequence
Common evidence of common ancestry among organisms includes similarities in DNA sequences, anatomical structures, and embryonic development. Comparative studies show these shared characteristics among different species, indicating that they share a common ancestor. This supports the theory of evolution and the idea that all living organisms are connected through a shared evolutionary history.
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.
all organisms share a common evolutionary ancestry. The universal presence of DNA suggests a common genetic code that has been inherited from a common ancestor. This supports the theory of evolution and the idea that all living things are connected through a shared genetic history.
Molecular evidence for evolution includes DNA sequencing, which reveals similarities in the genetic code across species. By comparing the DNA sequences of different organisms, scientists can infer evolutionary relationships and common ancestry. Additionally, the presence of pseudogenes and shared genetic markers further supports the idea of evolution through common descent.
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.
