Characters that provide evidence for evolutionary relationship are homologous analogous taxonomic convergent morphological
Jennifer Stoner
Which of the following is a correct interpretation of the wings of bats and the wings of birds? they are homologous because the common ancestor of bats and birds had wings they are not homologous because their similar internal bone structure evolved independently as an adaptation for flight they are homologous because they are adapted for the same function they are homologous because they have similar internal bone structure inherited from a common ancestor they are not homologous because wings evolved from different ancestral organs in birds and bats
