As an Oxford palaeontologist who has been working on this problem since 1966, I have been asked for my opinion on the veracity of its claims. There is a misplaced fixation upon beasts of the Burgess Shale.

Below are outlined some of what I take to be its more laughable misunderstandings. So antiquated is this view that the screenplay for this film could have been written by teachers in 1954, or even by Mack Sennett at Keystone studios in 1912, just after the Burgess Shale biota was first reported by Walcott.

These included archaeocyathan sponges and many small shelly fossils. Did the film producers suffer amnesia at this point in the story? Small steps can be made very quickly indeed – as with virus evolution today. The film appears to have been shot within the walls of Cambridge University UK, with interviews taking place in the Sedgwick Museum, or around colleges such as St John’s and King’s College.

Or did that great prankster – the Intelligent Designer – make some big mistakes? Some think they perceive some blue highlights around the faces here, suggesting blue-screen shots in which the Cambridge settings have been imposed later.
