We like to think that humans are special, and we are but we are not one of a kind. The past thirty to frothy thousand years in human history have been really unique in the sense that we are alone on our planet. Earlier than this and there were always different types of humans around, those that we met and mixed with.
Thanks to well preserved DNA we now know that there were at least four other distinct types of human on the planet at the same time as us. There could even have been more than that but we just haven’t discovered yet. All of these other forms of humans however have been lost in time.
In this episode of Horizon, Alice Roberts sets out to explore the latest discoveries in the study of human origins, we discover the vast advances which are transforming this field of study thanks to our modern understanding of genetics.
These advances in genetics have also led us to discovering that our ancestors met and interacted with these other types of humans, in ways that still affect us today. Alice herself uses these revelations to update our picture of the human family tree.
