Conspiracy Theories, what are they? Why do we believe them? Are any of them true? This week Peter and Russell look at Conspiracy Theories, some of the reasons people believe them and what are some of the more popular ones today.

Have you ever heard a "fact" and thought, wow that's really interesting? Maybe you heard something and thought it was so enjoyable to know that you have repeated it yourself. How do you know it's true? Join Peter and Russell as we take a look at some of the famous facts that people have been told that have turned out to be untrue. Why did we believe them in the first place? Where did they come from? and how do we know that they're not true?

Did you know that the Neanderthals were not the only other human species that lived? At one time we shared this planet with about 5 other "homo" species and we believe our human ancestry was made up of at least 14 other human species. This week Peter and Russell will take a look at our ancestral family tree and find out what other hominins lived before and while we were around. What did we share with them? What did we learn from them? and most important of all What happened to them and why are we the only one's left?
