Millions of years have they survived to become the honey bees we know today - Apis Mellifera. They are highly efficient in pollinating crops and without them it would be very likely that our diet would become a lot sparser and more expensive. While old hollow trees in forests provided them with many suitable nesting places, it is with regret to say that those are becoming more and more rare. Now, they find their new housing in chimneys, attics, hollow walls, compost bins and the hives that humans have created. It's not easy - pesticides, habitat loss, exotic pests and predators, climate change, and more - make it a challenge to ensure their survival in long term. But as long as they can, they'll happily buzz around in search for flowers.
