Not too sure about the scientific content, but it certainly sounds like a different addition on the Darwin celebrations this year.
Here's the blurb from the Soho Theatre website:
On the 150th anniversary of the publication of Darwin's Origin of the Species, Nina Conti and 'the missing link', her foul-mouthed talking monkey, attempt to explain evolutionary theory. But with schizophrenia at close range, and with Monkey determined to sabotage her scientific credentials, she ends up unveiling far more than the Mysteries of Evolution... Thankfully, in the interest of entertainment, they've included songs, jokes and superfluous nudity. Winner of the Prestigious Barry Award at the Melbourne International Comedy Festival 2008.
