Multiple choice zoology origin of life and organic evolution neo darwinism mechanism of evolution other theories of evolution

Human population grows exponentially while food production grows at an arithmetic rate, leading to over population and social problem. This is :

  1. Krenze theory of population

  2. Malthus theory of human population

  3. Krenze theory modified by Malthus

  4. Malthus theory modified by Darwin
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

  • The principle of Malthusian theory of human population states that human populations grow exponentially (i.e., doubling with each cycle) while food production grows at an arithmetic rate (i.e. by the repeated addition of a uniform increment in each uniform interval of time). 
  • This scenario of arithmetic food growth with simultaneous geometric human population growth predicted a future when humans would have no resources to survive on. To avoid such a catastrophe, Malthus urged controls on population growth.
So, the correct option is 'Malthus theory of human population'.
