The fact that sheep insulin can be substituted for human insulin is an example of evidence of evolution based on comparative biochemistry. Insulin is a peptide hormone.
Comparative anatomy does not prove evolution itself, but is strong evidence because it shows that animals and species do change through periods of time; if evolution were not so, there would be no comparison possible since they would either be exactly the same or they would be different species.

Yes, a theory should be supported by evidence in order to be considered valid and credible. Evidence helps to substantiate the claims and predictions made by a theory, allowing for testing, verification, and refinement of the theory as needed.
The 3 major areas of evolution: homologies, fossil evidence and geographical distribution of speciesA. Homology or similarities between and across species is a key evidence for evolution. The theory goes that species that are related to each other share similarities that were derived from a common ancestor. For example, the forelimb of tetrapods: i.e. the arm of a human, flipper of a dolphin, wing of a bat, and the wing of a bird--reveal similar structures. When compared to a common ancestor such as the Eusthenopteron -- one can see that each aforementioned descendants retains some of the same ancestral characteristics.B. Fossil are remnants of organisms fro past geological times that have been encased in rocks. Through radioactive dating, scientist can determine the approximate age of the fossils. In addition, by examining each stratigraphic levels (rock layers)--scientists can make assessments that for example if an when an organism originated and died out. Comparative studies of fossil records with now-living organisms can be used to show how that organism or related ones evolved over time.C. Different species can be found in geographic regions. Some species can also be found in one region. For example, the flightless cormorant can only be found on the Galapagos Island. Other cormorants found in other regions still retain the ability to fly.
All of the above examples are direct evidence for evolution. Genetic changes in plants, antibiotic resistance in bacteria, and pesticide resistance in insects all demonstrate how species can adapt and evolve to survive in changing environments. This supports the theory of evolution by natural selection.
Prove is a term used in math. Comparative biochemistry supports with many lines of converging evidence the theory of evolution by natural selection. For a brief example consider cytochrome C, the electron shuttle that shuttles electrons between the I and II complex of the electron transport chain. This biochemical process is highly conserved in many types of organisms, being remarkably the same process from organism to organism, but showing the expected slight genetic variation that can be tracked down the taxa to support the common ancestry of evolution.
direct evidence is the observation of evolution as it occurs. We have discovered novel genes conferring an advantage in an environment in which the ancestral population lacked those genes entirely. One example is flavobacterium that evolved nylonase enzymes. Antibiotic resistance is another example.
Simple example. You know hair color is under genetic control. Two types, blond ( which is recessive ) and brown ( which is dominant ) exist in our population. These two alleles are in a 75% to a 25% frequency. ( dominant to recessive ) if that frequency changed to 60% to 40% you could say that evolution had taken place. Evolution is the change in allele frequency in a population of organisms over time. ( example very simplified ) PS Scientist do not prove things. They support their work with the evidence.

There are thousands of instances of direct evidence of evolution. The most well-known example is that of Darwin's Finches. These finches were observed through fossil records to have changed over time to adapt to their environment.
Comparative anatomy does not prove evolution itself, but is strong evidence because it shows that animals and species do change through periods of time; if evolution were not so, there would be no comparison possible since they would either be exactly the same or they would be different species.
The theory of evolution is supported by the fossil record, which reveals a chronological progression of species and transitional forms that illustrate gradual changes over time. Comparative anatomy shows similarities in the structures of different species, indicating common ancestry; for example, the forelimbs of mammals, birds, and reptiles have similar bone structures despite differing functions. Additionally, comparative embryology demonstrates that embryos of diverse species exhibit striking similarities in early development, further suggesting a shared evolutionary origin. Together, these lines of evidence reinforce the concept that species evolve and adapt over time through common descent.
Scientists use various lines of evidence, such as the fossil record, comparative anatomy, embryology, and genetics, to show that living things have changed over time. By studying these pieces of evidence, scientists can construct evolutionary relationships and track changes in species over generations. This accumulation of evidence supports the theory of evolution.
fossil evidence is when scientist study fossils to figure out how the animal died how it evoled
I suppose it is after all there are som many evidence about it for example the ancestor things to do with apes.
Dinosaur bones, plant fossil, sealife fossil the evidence proves that there were animals long ago, and can support evolution
