Question

is the bird arms and bat arms homologous and analogous

Answer 1

The arms are basically the limbs which are modified to wings in case of birds and bats.

The wings of the bat and the bird are analogous while the forelimbs are homologous in nature.

The forelimbs are modified into wings; both the bird and bats have nearly same sets of bones; which are called as homologous structures.

Answer 2

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

Convergent evolution describes the acquisition of the same biological trait in unrelated lineages.

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