How do accents develop?

I’m trying to understand how accents develop. For example, why do people from Australia, New Zealand, Canada, and the US all have different accents when certain regions in those countries were populated by people immigrating from the same region in the UK? (I.e. the west coast of Scotland.)

Edit: Thanks for all your replies. This is a really interesting topic!

Ever heard of the game ‘telephone’?

Behavior is adaptive, language is a cultural adaption that is literally created on the fly as we use it. We are improvising like jazz musicians all day with each other.

As babies we learn and copy every aspect of being that we observe around us. Then we put on a show of what we learned for our babies in turn. As humans iterate through this process stylistic differences will arise. 

Imagine the magnitude of organization and commitment required for those differences to not emerge through thousands of iterations.
