Hunter-gatherers still exist today in some parts of the world, especially in the Amazon basin in South America. In what ways might these communities be similar to or different from the hunter-gatherers of the Paleolithic age?

The hunter gatherers today are different from the ones in the Paleolithic age due to the fact that we are much more advanced technology wise. Even if we're talking about the amazon tribes they've had hundreds of years to advance the way they make their weapons. But they are also similar when it comes to the gathering aspect (I don't know this 100% so may want to fact check it)
