Concept:The statement describes a biological process that slowly changes an organism's characteristics over many generations.
Explanation:The changes mentioned are gradual and cumulative, meaning they build up step by step over time.
These changes are adaptive, as they help the organism adjust better to its environment.
They are heritable, so they can be passed from one generation to the next.
A very long period of time is required for such changes to become significant.
Once enough changes have accumulated, a completely new species may emerge.
This entire process is known as organic evolution.
Adaptation is only a single beneficial trait or adjustment, not the whole process.
Survival refers only to living long enough to reproduce, not to forming new species.
Interspecific competition describes rivalry between different species for resources.
None of these options describe the long-term origin of new species as fully as organic evolution does.
Answer:C. organic evolution
