Question

students are provided with labeled diagrams of forlimb structures for three organisms with homologous structures.
according to the above diagrams, which structures in figures 2 and 3 are homologous to c in figure 1?

Explanation:

Homologous structures are anatomical features in different organisms that have a similar underlying structure (derived from a common ancestor) but may have different functions. In Figure 1, structure C is a bone. In Figure 2, structure U is a bone that is homologous to C (as they are part of the fore - limb skeletal system with a similar basic bone structure, indicating a common evolutionary origin). In Figure 3, structure M is a bone that is also homologous to C (again, part of the fore - limb skeletal framework sharing a common ancestral bone pattern).

Answer:

M and U
