Match column 1 with column 2:
| COLUMN 1 | COLUMN 2 |
| A. Saltation | i. Darwin |
| B. Formation of life was preceeded by chemical evolution | ii. Louis Pasteur |
| C. Reproductive fitness | iii. de Vries |
| D. Life comes from pre existing life | iv. Oparin and Haldane |
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) -A-iii, B-iv, C-i, D-ii
| COLUMN 1 | COLUMN 2 |
| A. Saltation | iii. de Vries |
| B. Formation of life was preceeded by chemical evolution | iv. Oparin and Haldane |
| C. Reproductive fitness | i. Darwin |
| D. Life comes from pre existing life | ii. Louis Pasteur |
A. Saltation → iii. de Vries
DeVries believed mutation caused speciation and hence called it saltation (single step large mutation).
B. Formation of life was preceded by chemical evolution → iv. Oparin and Haldane
Oparin and Haldane proposed the theory that life originated from non-living matter through a process of chemical evolution. They believed that simple organic molecules formed first, which eventually led to the origin of life.
C. Reproductive fitness → i. Darwin
Charles Darwin emphasized the concept of reproductive fitness (also known as "Darwinian fitness"), which means the ability of an organism to survive and reproduce, passing on its genes to the next generation.
D. Life comes from pre-existing life → ii. Louis Pasteur
Louis Pasteur by careful experimentation demonstrated that life comes only from pre-existing life. He showed that in pre-sterilised flasks, life did not come from killed yeast while in another flask open to air, new living organisms arose from ‘killed yeast’.
