Question
Which of the following is NOT true?
- Organisms overproduce offspring.
- All variations are inherited
- Only favorable variations are inherited.
- Naturals election is the mechanism of evolution.
Hint:
All variations are not inherited.
The correct answer is: All variations are inherited
All organisms produce more offspring so that more can survive to adulthood and reproduce. This means that many of those offspring will die without reproducing. Only the survivors are able to reproduce and pass their traits on to their offspring. The offspring of the survivors would inherit the favorable adaptations. Organisms with unfavorable adaptations die before they can pass them on to offspring. Darwin firmly believed that natural selection is the mechanism of evolution.
Hence, All variations are inherited is false.
