WebHomologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features).Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species’ relatedness. Web27 feb. 2024 · The most important thing to remember about homologous structures is that they share common ancestry. In other words, only organisms that are somehow related to each other can have homologous structures. For example, a chimpanzee’s arm and a human’s arm are homologous structures.
