The other day, I watched a 3 part special about what makes us uniquely human from the rest of the animals on the planet, namely chimps. It was very interesting and I wanted to share it with you. I'm linking to each full length video and then below I will link to Science Talk's interviews with Alda about the show and other interesting things.
Here's some information from PBS:
After some three and a half billion years of life’s evolution on this planet – and after almost two million years since people recognizable as human first walked its surface – a new human burst upon the scene, apparently unannounced.
It was us.
Until then our ancestors had shared the planet with other human species. But soon there was
only us, possessors of something that gave us unprecedented power over our environment and everything else alive. That something was – is –
the Human Spark.
What is the nature of human uniqueness? Where did the Human Spark ignite, and when? And perhaps most tantalizingly, why?
In a three-part series broadcast on PBS in January 2010, Alan Alda takes these questions personally, visiting with dozens of scientists on three continents, and participating directly in many experiments – including the detailed examination of his own brain.
