Question

Are the arms of bat and bird homologous or analogous? Please justify.

Answer 1

analogous because bats and birds do not share a common ancestor, thus it is an example of convergent evolution.

Homologous are traits shared between different species that share a common ancestor.

Answer 2

Analogous are traits that are shared between different species that do not share a common ancestor

Answer 3

I learnt that analogous organs are same in function but different in structure, whereas homologous organs are those which are same in structure but different in function. So, I couldn't understand your answer. please explain in more simple words.

Answer 4

Structure dictates function

Answer 5

Yeah, that's true.

Answer 6

Well Bat arms and bird arms are the same in function and different in structure so obviously they are analogous.

Answer 7

They both exist to facilitate flight

Answer 9

so you basically just answered your own question by giving the definition of analogous

Answer 10

I just had a doubt. Lot of thanks for clearing it. Cheers!!!!!!!!!
