The Human Spark is a new three-part documentary special on PBS in which Alan Alda soldiers after the genetic and cognitive elements that make him smarter than your average chimpanzee. In the first episode, he travels to numerous archaeological sites and many of the world’s finest research centers to look at how humans diverged from neanderthals and why we’re the ones writing the history books. Episode two tracks a series of experiments on chimpanzees and human children to illustrate the psychological differences. The final installment shows off some of the latest brain imaging studies and and linguistics research to postulate a theory on the nature of the ‘human spark’. With an interesting scientific premise as a basis, a hot field in which a lot of exciting, new information has been discovered within the last decade, and financial sponsorship by the Alfred P. Sloan Foundation, one of the most generous and prestigious in all of science, this should have been a knockout for PBS. Sadly, the finished product is merely another example of a strong concept with poor execution, punctuated by bloopers that the documentary’s creators were too pressed for content to take out.
