Evolution of a species over several generations

This MCQ is based on Evolution(It is a change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction).

Select the correct statement from the following options.

Mutations are random and directional. Darwinian variations are small and direction less. Fitness is the end result of the ability to adapt and get selected by nature. All mammals have evolved vivipary as an adaptation.

Which type of selection is industrial melanism observed in moth, Biston bitularia [NCERT Exemplar]

Stabilising Directional Disruptive Artificial

Missing link in evolution is:

Pheretima Limulus Peripatus Archaeopterys

Hardy-Weinberg principle explains :

Chromosomal Genetic drift Genetic equilibrium All of these

As per Neo-Darwinism, which is mainly responsible for evolution?

Mutation Natural drift Both of these All of these

Dispersal of population depends on:

On immigration On Emigration On Migration All of these

Evolutionary history of an organism is known as:

Ontogeny Phytogeny Ancestry Palaentolgy

Which of the following is used as an atmospheric pollution indicator?

Lepidoptera Lichens Lycopersicon Lycopodium.

The bones of forelimbs of whale, bat, cheetah and man are similar in structure, because

One organism has given rise to another

They share a common ancestor

They perform the same function

They have biochemical similarities.

Palaeontological evidences for evolution refer to the

Development of embryo

Homologous organs


Analogous organs.

Animal husbandry and plant breeding programmes are the examples of

Reverse evolution

Artificial selection


Natural selection.

The theory of spontaneous generation stated that

Life arose from living forms only

Life can arise from both living and non-living

Life can arise from non-living things only

Life arises spontaneously, neither from living nor from the non-living.

Homologous organs indicate

Convergent evolution.

Divergent evolution.

Adaptive radiation.

Natural selection.

Darwin judged the fitness of individuals by

Ability to defend itself.

Strategy to obtain food.

Number of offspring produced.

Dominance over other individuals.

Change of frequency of alleles in a population results in evolution. This statement is proposed in

Darwin’s theory

Lamarck’s theory

Hardy-Weinberg principle
