Question

What is most likely to occur if a new road is built through a forest and uses barriers throughout the forest?
The barrier will not affect the animals in the forest.
All animals in the forest will experience mutations. Over time, new animal species will be created and geographically separated using the barrier.
All animals in the forest will experience mutations. Over time, the barrier will geographically isolate the animals, resulting in new species in the forest for each animal species.
The barrier will initially geographically isolate all of the animals in the forest. Over time, each animal species will experience mutation, resulting in new species of all animals in the forest.

Answer 1

The most likely occurrence if a new road is built through a forest and uses barriers throughout the forest is:

The barrier will initially geographically isolate all of the animals in the forest. Over time, each animal species will experience mutation, resulting in new species of all animals in the forest.

This option accurately reflects the process of geographical isolation leading to evolutionary changes, where isolated populations may adapt to their specific environments over time, potentially resulting in the emergence of new species.
