Which one is the most acceptable and recent theory of organic evolution?
- A. Lamarckism
- B. Darwinism
- C. Isolation theory
- D. Synthetic theory
Answer: D. Synthetic theory
The most acceptable and recent theory of organic evolution is Synthetic theory, also known as Neo-Darwinism.
Synthetic theory combines Darwin’s natural selection with subsequent advancements in genetics, population genetics, and molecular biology. It explains how:
- Mutations introduce genetic variation in populations.
- Natural selection acts on these variations, favoring individuals with traits better suited to their environment.
- Over time, populations can change significantly through this process, leading to the evolution of new species.
