Question

what is the biological sense of evolution?
a change in species over successive generations.
the rapid mutation of a species in a year.
a change in a species environment.

Explanation:

To determine the biological sense of evolution, we analyze each option:

• The first option, "A change in species over successive generations," aligns with the scientific definition of evolution, as evolution involves gradual changes in populations of organisms over many generations due to mechanisms like natural selection, genetic drift, etc.
• The second option, "The rapid mutation of a species in a year," is incorrect because evolution is a long - term process that occurs over many generations, not rapidly within a year, and mutation alone is not the same as evolution (evolution is about changes in the gene pool of a population over time).
• The third option, "A change in a species' environment," is incorrect because evolution is about changes in the species itself (its genetic makeup and traits), not just its environment.

Answer:

A. A change in species over successive generations.
