Question

Describe Darwin's four postulates in your own words. What would have happened in the snapdrag- on experiment if any of the four had not been true?

Answer 1

Darwin's four postulates are: organisms have variations, some variations are heritable, organisms struggle to survive and reproduce, and variations that increase fitness are more likely to be passed on.

In the snapdragon experiment, if any of these postulates were not true, it would impact the outcome.

Step-by-step explanation:

Darwin's four postulates are:

1. Organisms have variations.
2. Some variations are heritable.
3. Organisms struggle to survive and reproduce.
4. Variations that increase fitness are more likely to be passed on.

In the snapdragon experiment, if any of these postulates were not true, it would impact the outcome. For example, if organisms didn't have variations, there would be no basis for natural selection to act upon.

Similarly, if variations were not heritable, there would be no transfer of advantageous traits to future generations. And if there was no struggle for survival or reproductive success, fitness would not come into play.
