A	Thomas Malthus	1	Branching descent
B	Hugo Vries	2	Studies on populations
C	Charles Darwin	3	Use and disuse theory
D	Lamarck	4	Saltation

• A. A - 4, B - 1, C - 2, D - 3
• B. A - 3, B - 2, C - 1, D - 4
• C. A - 4, B - 3, C - 1, D - 2
• D. A - 2, B - 4, C - 1, D - 3

Answer 1

The correct option is D A - 2, B - 4, C - 1, D - 3

1. Thomas Malthus stated through his studies on the populations that human populations grow exponentially while food production grows at an arithmetic rate. This scenario predicted a future when humans would have no resources to survive.

2. Hugo de Vries regarded single, large step mutations called saltation as the reason for evolution.

3. Darwin regarded natural selection and branching descent as the key concepts of the theory of evolution. Branching descent may be defined as the process by which new species originate from a single common descendant.

4. Lamarck proposed the theory of use and disuse of organs which state that if an organ is constantly used, it would be better developed whereas disuse of organ results in its degeneration.

So, the correct answer is 'A - 2, B - 4, C - 1, D - 3'.
