Question

A scientist who gave a theory very similar to that given by Darwin
A)Malthus
B)Wallace
C)Goldstein
D)Mendel

Answer 1

Darwin gave the theory of natural selection. The scientist who gave the theory similar to that on Darwin worked on plant and animal diversity and concluded the same as that of Darwin. He studied the animals and plants that were only typical to the Malay Archipelago.

Complete answer:
To solve this question, we must know about the theory that is similar to that of Darwin.
A British naturalist studied the organisms of Sulawesi. He said that these organisms are unique and are not found anywhere else. These organisms on the islands are isolated from the other population for a very long time. They evolved into new species. This happened due to natural selection and was put forward by Alfred Wallace. He independently proposed the theory of evolution and jointly published papers with Darwin and thus Darwin put forward his theory of Origin of New Species.

Malthus- He put forward the theory of population. He proposed that the population growth is exponential while the growth of food supply is linear.

Goldstein- The Goldstein is a German physicist who worked and discovered discharge tubes.

Mendel- Mendel is called the father of Genetics. He put forward the theory of Inheritance. He said that the unit of inheritance is the basis of transfer of characters from parents to offspring.

Hence, the correct answer is option (B)

Note: Wallace is known as the “father of biogeography”. He did extensive fieldwork in the Amazon river basin followed by Malay Archipelago. He identified the faunal divide which is now termed as Wallace line. He also believed in transmutation of species.
