What of the following is NOT a postulate of Lamarck’s theory of evolution?
Use and disuse of organs
- Acquired traits are inherited
Natural selection is the mechanism of evolution.
Organisms are driven to greater complexity.
Use and disuse of organs
Natural selection is the mechanism of evolution.
Organisms are driven to greater complexity.
Hint:
3 main theories of evolution are: (I) Lamarckism or the Theory of Inheritance of Acquired characters. (II) Darwinism or the Theory of Natural Selection. (III) Mutation theory of De Vries.
The correct answer is: Natural selection is the mechanism of evolution.
Lamarck's theory includes four main propositions:
- Change Through Use And Disuse.
- Organisms Driven To Greater Complexity. ...
- Inheritance of Acquired Characters. ...
- Effect of Environment and New Needs.
But natural selection is a postulate of Darwinism theory.
