EVOLUTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Bats and birds are only very distantly related, and both evolved wings for flight in very different evolutionary pathways.What is the term that describes the wing structures that these species evolved?
A
analogous structures
B
divergent structures
C
embryonic structures
D
homologous structures
Explanation: 

Detailed explanation-1: -Birds and bats have homologous limbs because they are both ultimately derived from terrestrial tetrapods, but their flight mechanisms are only analogous, so their wings are examples of functional convergence. The two groups have independently evolved their own means of powered flight.

Detailed explanation-2: -This is called convergent evolution.

Detailed explanation-3: -Bird and Bat wings are analogous because they evolved independently. But the wing bones are homologous because they were inherited from the common ancestor.
