Question

Natural selection causes what to occur?

1. evolution
2. survival of the fittest
The law of independent assortment
3. Mendel's law of segregation
4. genetic drift

Answer 1

1. evolution

Step-by-step explanation:

Natural selection causes populations to become adapted, or increasingly well-suited, to their environments over time. Natural selection depends on the environment and requires existing heritable variation in a group.

Answer 2

(1.) Natural selection causes evolution to occur.

Step-by-step explanation:

Over time, the naturally occurring variation within a population that arise from mutations, alter in frequency. Some of these variants or traits, may confer advantages to certain organisms, allowing them to reproduce and pass on genes more successfully. These traits become fixed within the population, and eventually the individuals evolve to form a species.

Natural selection, acts on evolution, for or against traits. It ensures that individuals with traits well-suited to their environments and reproductive fitness survive.
