Which of the following are homologous organs
1 Wings of birds \& Locust
2 Wings of birds (Sparrow) \& Pectoral fins of fish
3 Wings of bat \& Butterfly
4 Legs of frog \& Cockroach
Explanation:
Homologous organ - which have the same origin and similar basic structure but may differ in external appearance and function. E.g.- Wing of birds and pectoral fins of fish. Analogous organ-Anatomically different but functionally same. e.g: (a) Wings of birds and locusts (b) Wings of bat and butterfly. (c) Pectoral fin of shark and flipper of dolphins.

Which of the following statements is not true?
1 Flippers of penguins and dolphins are a pair of homologous organs
2 Analogous structures are a result of convergent evolution
3 Sweet potato and potato is an example of analogy
4 Homology indicates common ancestry
Explanation:
Flippers of penguins and dolphins are analogous organs as they help in swimming but do not have the same structure. These result in the convergent evolution. - Homologous organs have the same structure but have different functions, according to the needs of the organisms. Hence homology indicates common ancestry. - Analogous organs have developed for the same function but do not show a similarly in structure. Hence they are a result of convergent evolution. - Ex- Wings of birds and insects that perform the same process that is flying. insects wings are the outgrowths of the insects exoskeleton that enable insects to fly. Bird wings are a paired forelimb in birds.

The classical example of adaptive radiation in development of new species is
1 Darwin finches
2 Marsupials of Australia
3 Giant turtle
4 All of the above
Explanation:
The classical example of adaptive radiation during formation of new species is marsupials of Australia, Darwin's finches and giant Tortoise. Adoptive radiation is the rapid diversification of a single species into a variety of new species that occupy different ecology niches. Darwin finches are a group of 18 species of finches that are found on Galapagos Islands in Antarctica region. The finches have evolved different beak shapes and sizes.

An evolutionary process, giving rise to new species adapting to new habitats and ways of life is called
1 adaptive radiation
2 adaptation
3 convergent evolution
4 microevolution
Explanation:
Adaptive radiation - Adaptive radiation (= Divergent evolution). Development of different functional structures from a common ancestral form for adapting to new habitats and ways of life is called adaptive radiation. The concept of adaptive radiation in evolution was developed by H.F. Osborn in 1898. Example. Darwin's finches of the Galapagos islands had common ancestors but how have different types of modified beaks according to their food types of modified beaks according to their food habits.
