Im Neolithic Nel. Back when I was paleolithic Nel we did not have any jobs because our only priority was food and saftey.
One important change in developing new jobs was that people were able to specialize in one thing and be very good at it instead of not knowing how to do multiple jobs.
Another important change in developing jobs is it gave people way more time to make way better designs of things that are way more complex because neolith people loved to surround themselves with beautiful things.
This topic is inmporntant because it gave people the opportunity to get really good at one thing to make the best of that one thing which made people do trade for other things which started the topic of trade that we all use now today.
