How is it that Aborigines light fires by rubbing pieces of wood together?
Rubbing things together creates heat. Enough heat, and stuff like wood catches fire. It's a way of starting fires that's almost always available, if you have the skill and some suitable pieces of wood. You don't need any special lighting equipment like matches, lighters, or flint and steel.
Why do aborigines light fires by rubbing pieces of wood together?
Rubing two pieces of wood together rapidly and consistently can cause enough friction to heat the wood to the point of ignition. However these days I doubt if there are many aboriginals that would light a fire that way. a lighter is much easier.

How do the Australian aborigines make poisonous foods edible?
I think alot of the food that they eat thet is 'poisonous' contains large amounts of Tanin. They wash and boil certain foods for sometimes hours or cook them underground under fires for a long amount of time. Further information: The Aborigines also knew how to make them digestible, by including all parts of the plant. For example, the Aborigines of Cooper Creek lived on nardoo, but when explorers Burke and Wills tried to eat it, they simply starved to death. This was because they did not include all parts of the plants which enables absorption of the nutrients.
