Episode 2 One Voice in the Cosmic Fugue

This episode was more about biology and evolution than astronomy. Carl is definitely an evolution proponent. I'm a little more flexible in letting people use their "Faith" to decide how much of the evolution story they wish to buy into. On the other hand, I don't think topics like "Intelligent Design" should be portrayed as science.
In regards to the chance of extraterrestial life, it is heartening to know that Earth's life uses the most common chemical element building blocks of the Cosmos. He also implies that the leap from simple microbial life to inteligent civilizations might be as great as the leap from inert chemical to simple life. I hope that we can soon search locations like Mars, Titan, Enceledus and Europa to see if the Solar System has another sample of simple life. Computing chances of life within the Milky Way or the Cosmos is so hard when you only have one occurance to work with.
With his 10 year followup comments, it's interesting that the asteroid explosion 65 million years ago was new information. It shows how scientific thinking modifies over time.
