The name Galapagos islands has been given on the basis of occurrence of 

  1. Black cooled lava

  2. Giant Tortoises

  3. Giant iguanas

  4. All of the above


Correct Option: B
Explanation:
  • The Galapagos Islands are located in the eastern Pacific Ocean, 973 km off the west coast of South America.
  • Galapagos islands discovered in 1535 by a Spanish bishop named Fray Tomas de Berlanga, he named the island Galapagos after the impressive giant tortoises found there.
  • Hence the name Galapagos islands have been given on the basis of occurrence of Giant Tortoises.
  • So, the correct answer is 'Giant Tortoises'.

The term Darwin's finches was given to Galapagos finches by 

  1. Huxley

  2. Spencer

  3. Wallace

  4. Lank


Correct Option: D
Explanation:
  • The term Darwin's finches was given to Galapagos finches because, On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection.
  • Darwin's finches comprise a group of 15 species endemic to the Galápagos (14 species) and Cocos (1 species) Islands in the Pacific Ocean.
  • The term Darwin's finches was given to Galapagos finches by David Lank in the book Darwin's finches.
  • So, the correct answer is 'Lank'.

Darwin's finches occur in 

  1. Australia

  2. Galapagos islands

  3. Siberia

  4. India


Correct Option: B
Explanation:
  • The term Darwin's finches was given to Galapagos finches because, On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection.
  • Darwin's finches comprise a group of 15 species endemic to the Galápagos (14 species) and Cocos (1 species) Islands in the Pacific Ocean.
  • Hence Darwin's finches occur in Galapagos islands.
  • So, the correct answer is 'Galapagos islands'.

Galapagos Islands were visited by :

  1. Wallace

  2. Darwin

  3. Lamarck

  4. De Vries


Correct Option: B
Explanation:

The Galapagos Islands were prominently featured in Charles Darwin's landmark book on evolution, The Origin of  Species. On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection.

So, the correct answer is 'Darwin'

Darwin was most influenced by :

  1. Lamarck's theory of acquired characters

  2. Weisman's theory of origin of species

  3. Wallace's theory of origin of species

  4. Essay on Population by Malthus


Correct Option: D
Explanation:

Thomas Malthus' work helped inspire Darwin to refine the natural selection by stating a reason for meaningful competition between members of the same species. Not surprisingly, Malthus, an ordained minister, believed that hunger and disease were aspects of life implemented by God to stop populations from exploding. Malthus was an influence through his book 'Essay on Population'

So, the correct answer is 'Essay on Population by Malthus'.

Which book was written by Charles Darwin?

  1. Origin of species

  2. Species Plantarum

  3. Genera Plantarum

  4. De Naturien Familien


Correct Option: A
Explanation:
 Origin of Species Charles Darwin 
 Species Plantarum  Carl Linnaeus
 Genera Plantarum  Carl Linnaeus Armand's Neo
 De Naturien Familien   Armand's Neo

So, the correct answer is 'Origin of Species'

'Origin of Species' was written by :

  1. Oparin

  2. Weismann

  3. Lamarck

  4. Darwin


Correct Option: D
Explanation:

On the Origin of Species (or, more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life), published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology.

So, the correct answer is 'Darwin'

Most important theory of general biology was proposed by :

  1. Mendel and Morgan

  2. Beadle and Tatum

  3. Watson and Crick

  4. Darwin and Wallace


Correct Option: D
Explanation:

The most important theory of general biology is the theory of evolution by natural selection. In the early 19th century Jean-Baptiste Lamarck (1744 – 1829) proposed his theory of the transmutation of species, the first fully formed theory of evolution. In 1858 Charles Darwin and Alfred Russel Wallace published a new evolutionary theory, explained in detail in Darwin's On the Origin of Species (1859).

So, the correct answer is 'Darwin and Wallace'

Which was not proposed by Darwin?

  1. Struggle for existence

  2. Natural selection

  3. Genetic drift

  4. Survival of the fittest


Correct Option: C
Explanation:

The main concept of Darwin's theory was natural selection. Other main points were High rate of reproduction, Total number almost constant, Struggle for existence, Variations, Survival of the fittest. It didn't had genetic drift. Hence, option C is correct.

Darwin's theory of pangenesis proposes __________.

  1. Some physical basis of inheritance.

  2. Development of useful organs and degeneration of useful organs.

  3. Increase in organ size with age

  4. Development of organs due to will power.


Correct Option: A
Explanation:

In 1868, Darwin put forward the Theory of Pangenesis. According to this theory, every organ of the body produces minute hereditary particles, called gemmules or Pangenes, and they can be carried through the blood into the gametes. It laid emphasis on some basis of inheritance. Hence, Option A is correct.
