Here's a breakdown:

* Inherited trait: A characteristic passed down from parents to offspring through genes.

* Survival: The ability to stay alive in a particular environment.

* Reproduction: The ability to produce offspring.

* Environment: The surrounding conditions in which an organism lives.

Adaptation is a key concept in evolution. Organisms with beneficial adaptations are more likely to survive and reproduce, passing those adaptations on to their offspring. Over time, this can lead to changes in the characteristics of a population.
