When the protein structure changes there has been evolution in the organism
Anatomical embryological evidence refers to similarities in developmental patterns and structures among different organisms, providing insights into their evolutionary relationships. Biochemical evidence involves comparisons of proteins, DNA sequences, and other molecules to understand evolutionary relationships. Both types of evidence can complement each other in confirming evolutionary relationships between organisms.

Biochemical analysts use similarities in molecules like DNA, proteins, and enzymes as evidence for evolutionary relationships. The more similarities there are between the molecules of different organisms, the closer their evolutionary relationship is believed to be.

Determining the natural variations that exist in physical evidence
Biochemical evidence of evolution is considered indirect because it does not provide direct evidence of specific evolutionary events or transitions in the fossil record. Instead, it demonstrates similarities in molecular structures or sequences across different species, which support the idea of a common ancestor but do not directly show the process of evolution occurring.
Physiological similarities suggest the species evolved from the same ancestor.

Biochemical evidence of evolution is considered indirect because it does not provide direct observation of evolutionary changes happening over time. Instead, it relies on comparing similarities and differences in biochemistry, such as DNA sequences or protein structures, to infer evolutionary relationships among organisms.
