Question

question 2 1 pts reproductive isolation is to speciation as natural selection is to ecological isolation. polyploidy. hybridization. adaptive evolution.

Explanation:

To solve this, we analyze the relationship: Reproductive isolation is a key mechanism for speciation (the formation of new species). Natural selection is a key mechanism for adaptive evolution (evolution that leads to organisms being better adapted to their environment). Let's check other options: Ecological isolation is a type of reproductive isolation, not related to natural selection's role. Polyploidy is a chromosomal change, not linked to natural selection. Hybridization involves mixing genetic material, not the role of natural selection. So natural selection drives adaptive evolution, matching the relationship of reproductive isolation to speciation.

Answer:

D. adaptive evolution
