Answer:
You can find collision zones on the edge of the Pacific Ocean offshore Washington, Canada, Alaska, Russa, Japan, and Indonisa.
Explanation:
Generally speaking, there are 2 major forces that cause genetic divergence in the majority of populations and systems.
And those are;
Natural Selection
and
Mutation
Natural selection causes a divergence due to the fact that organisms with " "better", more advantageous traits dependent on their environment, survive and reproduce, while the others have the lesser chance. (This causes traits in the population to change over time.)
Mutilation/Mutations, on the other hand, is a change in the genetic material of an organism-specifically when DNA is copied incorrectly.
This changes a portion of the genetic makeup of an organism, therefore changing the organism, and changing its future generations of offspring (when made...etc)
