How Can Morphology Show That Organisms Are Related

Prior to the advent of Darwinism, homology was attributed to the existence of. then it should be possible for them both to appear in the same organism. So, if evolution is to provide an adequate explanation for homology, it is necessary to show. In particular, if similar morphological structures (structures that appeared.

Comparing the features of one organism to another helps scientists learn about both. While logic decrees that those with the most similar morphology are most.

(I prefer "preying" rather than "praying" because I don't think these insects are. It culminates in unrelated organisms with similar morphological characteristics even. However, several examples show that the same phenotype might evolve.
