Analogous structures are physically similar structures that evolved independently. Examples include bat and bird wings. Thorn and spine, as well as tendril comparisons, are not analogous structures.
Analogous structures refer to physically similar structures between two taxa that evolved separately. They do not share an evolutionary history but serve similar functions. One example of analogous structures is the wings of a bat and bird, which evolved independently.
On the other hand, thorn and spine are not examples of analogous structures as they may have different functions and can be homologous in certain cases.
Similarly, the tendril of Lathyrus and Gloriossa being compared are not analogous structures as they may have different embryonic origins despite serving a similar function.
