FACTOID #53: If you thought Antarctica was inhospitable, think again - its land area is only ninety-eight percent ice. Reassuringly, the other 2% is categorised as "barren rock".
The wings of pterosaurs (1), bats (2) and birds (3) are analogous: they serve the same function and are similar in structure, but each evolved independently.
Two structures in biology are said to be analogous if they perform the same or similar function by a similar mechanism but evolved separately. Similar structures may have evolved through different pathways, a process known as convergent evolution, or may be homologous. Image File history File links No higher resolution available. ...

In evolutionary biology, convergent evolution is the process whereby organisms not closely related, independently evolve similar traits as a result of having to adapt to similar environments or ecological niches. ... In biology, homology is any similarity between structures that is due to their shared ancestry. ...
The concept of analogy is contrasted with that of homology, which refers to two structures that share a common ancestor and share basic structure. Homologous structures may retain the function they served in the common ancestor or they may evolve to fulfill different functions for example, the wings of birds versus the forelimbs of mammals. Analogy is both the cognitive process of transferring information from a particular subject (the analogue or source) to another particular subject (the target), and a linguistic expression corresponding to such a process. ...

Analogy is either the cognitive process of transferring information from a particular subject (the analogue or source) to another particular subject (the target), or a linguistic expression corresponding to such a process.
In a narrower sense, analogy is an inference or an argument from a particular to another particular, as opposed to deduction, induction, and abduction, where at least one of the premises or the conclusion is general.
Analogy is important not only in ordinary language and common sense, where proverbs and idioms give many examples of its application, but also in science, philosophy and the humanities.
Analogies are often used to explain new or complex concepts by showing the similarities between them and familiar concepts.
Analogy from previous judicial decisions is also common, although these decisions are not binding authorities.
Analogies are thus usually drawn from precedent cases: The judge finds that the facts of another case are similar to the one at hand to an extent that the analogous application of the rule established in the previous case is justified.
