Which option BEST describes the evolution of these features of bats and birds?
The forearms of the birds and bats are similar in structure, so this feature came from a common ancestor. The wings of birds and bats are not similar in structure so this feature did not come from a common ancestor.
The forearm of the birds and bats are similar in structure, so this feature did not come from a common ancestor. The wings of the birds and bats are not similar in structure so this feature came from a common ancestor.
The forearms of the birds and bats are similar in function, so this feature came from a common ancestor. The wings of the birds and bats are not similar so this feature did not come from a common ancestor.
The forearms of the birds and bats are not similar in function, so this feature did not come from a common ancestor. The wings of the birds and bats are similar so this feature did not come from a common ancestor.
An index fossil is useful to determin the ages of different organisms. Which of the folling fossils would make the BEST index fossil?
Based on both figures, what can be inferred about the limbs of a bat and a bird?
Bats and birds are two closely related animals
Bird ancestors had four limbs and bat ancestors had two limbs
Bats and birds are both relted to frogs and other amphibians
Bat ancestors are more closely related to humans than to birds
