Some dinosaurs had feathers although they could not fly but birds have feathers that help them to fly. In the context of evolution this means that 
(a) reptiles have evolved from birds 
(b) there is no evolutionary connection between reptiles and birds 
(c) feathers are homologous structures in both the organisms 
(d) birds have evolved from reptiles

Answers (1)

Answer: (d)

Solution:
In the context of evolution, the use of feathers by birds for flying means that birds have evolved from reptiles. Dinosaurs had feathers but could not fly using them. Birds later adapted the feathers for flight. Since dinosaurs were reptiles, this means that birds have evolved from them.

Therefore, option (d) is correct.
