Analogous structures and convergent evolution
The wings of bats and the wings of insects both enable flight but develop from different embryonic structures. These wings are:
Answer A: explanation for every choice
A
Correct. Similar function from different origins reflects similar selective pressures, not shared ancestry.
B
Homologous structures share developmental and evolutionary origin, such as bat wings and human arms.
C
Vestigial structures have lost most of their original function.
D
Divergent evolution produces homologous structures with different functions.
TakeawayAnalogous: same function, different origin. Homologous: same origin, possibly different function.
