Final answer:
A strictly evolutionary worldview is often associated with atheism and secular humanism, both of which accept evolution without invoking the divine. Biology does not support or negate the existence of a deity, and many individuals and religious denominations reconcile their faith with evolutionary science.
Step-by-step explanation:
The worldview that aligns with a strictly evolutionary explanation for the origin of the universe is often linked to atheism and secular humanism. Both atheism, which is the lack of belief in a god or gods, and secular humanism, a philosophy that emphasizes human value and agency without recourse to the divine, can incorporate an evolutionary perspective on life's development. Evolution, as a scientific theory, does not directly address the existence of a spiritual realm; it is solely concerned with explaining the diversity and complexity of life on Earth through natural processes such as mutation, natural selection, and speciation.
While individual scientists might hold personal beliefs ranging from atheism to devout religious faith, biology as a discipline does not support or negate the existence of a deity. Evolution's explanatory power lies in its ability to account for the observed diversity of life, not in speaking to spiritual questions. Still, many individuals find ways to reconcile their spiritual beliefs with acceptance of evolutionary science, as most major religious denominations in the United States do not see evolution as incompatible with their theologies.
