Dr Alice Roberts asks one of the great questions about our species: are we still evolving? There's no doubt that we're a product of millions of years of evolution. But thanks to modern technology and medicine, did we escape Darwin's law of the survival of the fittest? Alice follows a trail of clues from ancient human bones to studies of remarkable people living in the most inhospitable parts of the planet and the frontiers of genetic research, to discover if we are still evolving - and where we might be heading.

We have a relationship with few things in nature the way we do with snow: we hate it, we love it, and we think we understand it. But we barely know the contradictory and beautiful components of snow’s character. But that’s something scientists are changing. From the formation of single flakes to the howling 70 km/h winds of lake effect snow storms to the destructive power of avalanches, intrepid researchers are bringing snow science into the 21st Century.

What are the origins of life? How did things go from non-living to living? From something that could not reproduce to something that could? Earth is estimated to be about 4.5 billion years old, and for much of that history it has been home to life in one form or another. Our planet is teaming with life, from the highest mountain to the deepest ocean; life is everywhere. But what was the firing pistol that started the evolutionary race? How did material go from non-living to alive? It's one of the most fundamental and difficult questions that has challenged us since the beginning of time.
