Evolutionists have had little success explaining this onetime event. Thomas H. Huxley likened it to a barrel that is filled rapidly with apples. Then it takes longer to fill the remaining spaces with pebbles, sand and finally water. Today’s explanations are more technical-sounding but no less reliant on speculation as opposed to direct description. Steven Stanley compared it to the introduction of bacteria croppers which prey on dominant species which previously had suppressed diversity. J. J. Sepkoski compared it to rapid growth of bacterial populations in a virgin petry dish. Were the Precambrian oceans a virgin ecosystem with the raw materials of oxygen and food supplied by ancient bacteria? Steve Jones wondered if the Cambrian explosion reflects some crucial change in DNA—life’s genetic material. "Might a great burst of genetic creativity," asks Jones, "have driven a Cambrian Genesis and given birth to the modern world?"
Now, thanks to new research, we have yet another explanation: calcium. Evolutionists are now saying that a rise in ocean calcium levels may have triggered the assembly of unicellular organisms into multicellular organisms and the rest, as evolutionists say, is history. As one report explained:
the question of what was the trigger for the single cell microorganisms to assemble and organize into multicellular organisms has remained unanswered until now.
What is astonishing is that there is anyone left out there who questions evolution. Can't they see that these guys are doing the heavy lifting? This is just rock solid investigative research, the kind we've come to expect from evolutionists.
