Answer:
The surface and atmosphere of Earth has been changing constantly throughout its history as a result, organisms continue to evolve to adapt to those changes only by evolutionary term.
Step-by-step explanation:
- Survival of the fittest - It refers to the 'survival of organisms' which are best able to 'obtain and utilize' the available resources that results in the 'evolution of organisms' which can adapt to these changes.
- Survival alone is not sufficient for 'evolution of organisms, it's 'reproduction passing on of genes' that really counts.
