Question 40 2.25 pts Homology can be a confusing concept. The same structure can be referred to as homologous or analogous, depending on what specifically is being referred to. For example, the bones of the wing in bats and birds are homologous. However, the function of those bones in supporting flight is analogous (i.e. independently/convergently evolved). They key difference between homology and analogy is: Homologous traits are traits that are similar due to common ancestry Convergent evolution doesn't makes sense from a functional perspective, it evidence of contingency and randomness in evolution Homologous traits are traits that have to share the same function in the organism Homologous traits define polyphyletic groups. The function of a trait can never be homologous across species, but is always independently evolved and analogous

Homology can be a confusing concept. The same structure can be referred to as homologous or analogous, depending on
