Badal appeared in class test but he confused to know the incorrect statement. Would you help him to know that?

Organic evolution is a sequence, about to sudden changes which take place in the primitive organisms under hundred years in which new species are produced. Those organs which have the same basic structure but different functions are called homologous organs. The remains for impressions of dead animals or plants that live in the remote past are known as fossils. Those organs which have different basic structure for different basic design but have similar appearance and perform similar functions are called analogous organs.

In peas, a pure tall plant (TT) is crossed with a short plant (tt). The ratio of pure tall plants to short plants in F2 is

1 : 3 3 : 1 1 : 1 2 : 1

One Two Three Four

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

Reptiles have evolved from birds There is no evolutionary connection between reptiles and birds Feathers are homologous structures in both the organisms Birds have evolved from reptiles

Natural selection is called ‘survival of the fittest’. Which of the following statements best describes an organism?

None of the above

The process by which new species develop from the existing species is known as

Evolution Natural selection Artificial selection Speciation
