A new study challenges decades of conventional wisdom on what caused the geologically sudden rise of multicellular life on earth. So what mechanism triggered the Avalon explosion and other similar infusions of new life? And is it a science stopper to use intelligence or mind as a working hypothesis? On this ID The Future, we welcome back paleoentemologist Dr. Günter Bechly to answer these questions and more. A 1959 paper argued that an increase in oxygen content was a pre-condition for the rise of the first complex macro-organisms. This became mainstream consensus for decades. But a new study shows that this geologic event, known as the Avalon explosion, was actually precipitated by a drop in oxygen levels. Dr. Bechly explains the new paper's findings. He also explains the type of mechanism that has the power to produce the effects in question.
