1. Carolus Linnaeus

2. Charles Darwin

3. J. B. Lamarck

4. Ernst Mayr

Q.

Q. Any population has variations in characteristics. Those characterisatics enable some to survive better in the nature. Darwin called this as .

1. natural selection
2. origin of species
3. survival of fittest
4. Darwinism

Q. Which one of the following phenomena supports Darwin’s concept of natural selection in evolution?

1. Development of transgenic animals
2. Production of ‘Dolly’, the sheep by cloning
3. Prevalence of pesticide-resistant insects
4. Development of organs from stem cells for organ transplantation

Q.

Which of the following scientist is not related with organic evolution?

1. T.R. Malthus

2. C.D. Darlington

3. Erasmus Darwin

4. Charles Darwin

Q. Which one of the following sequences was proposed by Darwin and Wallace for organic evolution?

1. Overproduction, variations, constancy of population size, natural selection
2. Variations, constancy of population size, overproduction, natural selection
3. Overproduction, constancy of population size, variations, natural selection
4. Variations, natural selection, overproduction, constancy of population size

Q. Which of the following is the correct sequence of events in the origin of new species according to Darwinism?
I. Natural selection
II. Inheritance
III. Survival of the fittest
IV. Struggle for existence

1. I, II, III, IV
2. II, III, I, IV
3. III, IV, I, II
4. IV, II, III, I

Q. Read the following statements and identify the correct option that is a criticism of Darwin’s theory of evolution.

A. Darwinism explains the arrival of the fittest
B. Darwinism did not explain the evolution of terrestrial animals from aquatic forms
C. It explains the presence of vestigial organs
D. Darwinism did not differentiate between somatic and germinal variations

Q. Match column I with column II and select the correct option.
