Evolution 3

Development of different functional structures from a common ancestral form is called

• differential evolution

• adaptive radiation

• non-adaptive radiation

• regressive evolution

The process by which different type of finches were evolved in Galapagos islands is a consequence of

• adaptive radiation

• geographic similarity

• geographic dissimilarity

• adaptive convergence

The original finches from which other finches arose on Galapagos island were

• seed-eating

• insectivorous

• vegetarian

• carnivorous

Which one of the following aspects of evolution is shown by Darwin’s finches?

• Biogeographic evidence

• Industrial melanism

• Biochemical evidence

• Embryological evidence

The diversity in the type of finches and adaptation to different feeding habits on the Galapagos islands, as observed by Darwin, provides an evidence of

• origin of species by natural selection

• intraspecific variation

• intraspecific competition

• interspecific competition

Australian marsupials are the example of

• homologous radiation

• analogous radiation

• adaptive radiation

• convergent radiation

When more than one adaptive radiation appeared to have occurred in an isolated geographical area, it is

• convergent evolution

• divergent evolution

• natural selection

• genetic drift

The classical example of adaptive radiation in development of new species is

• Darwin’s finches

• marsupials of Australia

• locomotion in mammals

• All of the above

Example of convergent evolution is

• Darwin finches and marsupial mouse

• Placental wolf and Tasmanian wolf

• Placental wolf and Darwin finches

• Tasmanian wolf and marsupial mole

Which of the following is not an examples of adaptive radiation?

• Wombat, numbat, flying phalanger

• Darwin’s finches

• Different mammals in other parts of world

• Lemur and spotted cuscus
