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?

It's Friday the 13th, join us to find out about the superstitions that scare us, the reasons why we avoid walking under ladders and what you can do to be a Friday the 13th Survivor!

Join Peter and Russell for part 2 of their look at where are all the aliens. Touching on the Fermi Paradox and chatting about the challenges of space, from success and remembering those we lost to disaster. We even ponder the question of what if we are alone?
