Question

The theory of the human population was explained by
A.Charles Darwin
B.A.R Wallace
C.T.R. Malthus
D.Lamarck

Answer 1

Hint: Theory of population gives a relationship between the exponential population and the arithmetic food supply growth. According to this theory, the population grows in a geometric fashion. disequilibrium exists when the increasing population rate is greater than the food supply.

Complete answer: Charles Darwin published a book named ‘On the Origin of Species’ in the year 1859 on 24th November. The book published by Darwin was considered as the foundation of evolutionary biology. The full title of the book was ‘On the Origin of Species by Means of Natural Selection or the Preservation of Favored Races in the Struggle for Life'. In his book, he stated that the diversity of life descended from a common ancestor through evolution. Therefore, option A is wrong. A British naturalist, geographer, anthropologist, and biologist known as A.R Wallace is famous for conceiving the theory of evolution through natural selection which was published in the year 1858 along with some writings of Charles Darwin. So, option B is wrong. The theory of the human population was proposed by Thomas Robert Malthus in the year 1798. According to T.R. Malthus, a balance between population growth and food supply can be established by positive checks and preventions. So, option C is the correct answer. Jean-Baptiste Lamarck simply is known as Lamarck is best known for its inheritance of acquired characteristics. This theory is known as Lamarckism. Therefore, option D is wrong.
So, option C is the correct answer.

Note:According to the theory of human population if the rate of increase of human population is greater than the food supply then people will die to less amount of available food. The increasing population is indicated by the shortage of food supply.
