Which scientist /working is not matched correctly with its work / contribution ?

Options

A. Oparin and Haldane - Given most acceptable theory for origin of life .
B. Charles Darwin - Given most acceptable theory for evolution of life .
C. Thomas Malthus - He has written Assay on population .
D. Hugo de Vries - Gave the theory of germplasm .

Answer

To solve the question of which scientist's work is not matched correctly with its contribution, we will analyze each option provided:

1. **Operin and Haldane**: They are known for their theory of the origin of life, specifically the "primordial soup" theory. This theory suggests that life began in a watery environment with organic molecules forming under the influence of sunlight. This match is correct.

2. **Charles Darwin**: He is famous for his theory of evolution by natural selection. This theory explains how species evolve over time through the survival and reproduction of individuals with advantageous traits. This match is also correct.

3. **Thomas Malthus**: He is known for his essay on population, where he discusses the principles of population growth and its implications. This match is correct as well.

4. **Hugo de Vries**: He is known for his work on mutation and the concept of "mutation theory." However, the question states that he contributed to the "theory of germplasm," which is actually attributed to August Weismann. Therefore, this match is incorrect.

Based on the analysis above, the scientist whose work is not matched correctly with its contribution is **Hugo de Vries**.

**Final Answer**: Option 4 (Hugo de Vries - theory of germplasm) is not matched correctly.
