Fossils. These show the incredible amount of time required to turn early life forms into stone. Studying the fossils, one can see the similarities and evolution of species over time. UNREST.
Fossils can be used as evidence for evolution because they can show the development of a species over a long period of time.
Biochemistry is concerned with chemical substances and processes that occur within plants, animals and microorganisms. All life has prominent similarities at a molecular level. Organisms have basically the same:Genetic code in their DNAEnzymes used for basic metabolic processes, such as cellular respirationStructural Chemicals in their basic cell components, such as the phospholipids in cell membranes.
The types of evidence that are used to classify organisms including genetic similarities.
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.
All species have the same genetic code.
Related species have similar embryos.
this is because they have a link with early ancestors of similar structure.
Modern taxonomists use molecular evidence, such as DNA sequences, to classify organisms based on how their relationships changed over time. By analyzing similarities and differences in genetic material, taxonomists can determine the evolutionary relationships between different species and create more accurate classifications. This molecular evidence complements traditional morphological and ecological data to provide a more comprehensive understanding of evolutionary relationships among organisms.
If you mean, "are they ignorant for being in evolution," then no. The theory of evolution is a well-founded, heavily detailed theory with an enormous amount of evidence behind it. The theory of evolution is used to study disease. It's used to study agriculture. It's used to bring together all of the sciences pertaining to life.

Because it is more accurate than using physiological differences as used in the past.
