| | Homology |
 | | Evolution and homology are closely related concepts but they are not circular: homology of a structure is diagnosed and tested by outside elements: structure, position, etc., and whether or not the pattern of distribution of the trait is genealogical. | | | Homology is a specific explanation of similarity of form seen in the biological world. | | | According to Wells, textbooks should explain that homologies are similarities of structure and function due not to common ancestry but to a common "archetype" or basic plan on which all forms were based (Wells is remarkably cagey as to what he means by "archetype"). |

| | Efforts to correlate homology with developmental pathways, however, have been uniformly unsuccessful. | | | Even the classic example of vertebrate limbs shows that homology cannot be explained by similarities in developmental pathways. | | | The neural tube, embryonic precursor of the spinal cord, is regarded as homologous throughout the chordates, yet in some its formation depends on induction by the underlying notochord while in others it does not. |

| | His data are the only ones I have seen cited as evidence of [what] happens "in the wild." Majerus is attacked as "dishonest" and "text-book writers are lying to biology students", their behavior is "scandalous." [...] If Wells is right, he hasn't demonstrated it here. | | | In doing so he effectively denied any defensible meaning in the words such as deuterosome or ecdysozoan, well established higher taxa which have been erected on characters other than those genes that influence segment identity. | | | Only if symbols are construed to mean what they are not intended to mean can there arise imaginary, insoluble conflicts. |

| | Homology |
| | For example, organs as different as a bat's wing, a seal's flipper, a cat's paw and a human's hand have a common underlying structure, with identical or very similar arrangements of bones and muscles. | | | Homologous structures are structures that are derived from a common ancestor i.e. | | | Richard Owen also distinguished homology from analogy (also known as homoplasy), which he defined as a 'part or organ in one animal which has the same function as another part or organ in a different animal' (Owen, 1843: 374). |

| | Homology (biology) - Wikipedia, the free encyclopedia |
| | For two naturally occurring sequences, percent identity is a factual measurement, whereas homology is a hypothesis supported by evidence. | | | Asking whether two sequences are homologous is a yes-or-no question—there is no such condition as "degrees of homology." Sequence regions that are homologous may also be called conserved. | | | These similar structures evolved through different developmental pathways, in a process known as convergent evolution. |

| | In “Homology in Biology,” Paul Nelson and Jonathan Wells reexamine the phenomenon of homology-- the structural identity of parts in distinct species such as the pentadactyl plan of the human hand, the wing of a bird, and the flipper of a seal--on which Darwin was willing to rest his entire argument. | | | They argue that intelligent design can explain these anomalies and that it can also explain the other facts associated with the phenomenon of homology. | | | As such they argue that intelligent design provides a better explanation of homology than neo-Darwinism does |
