No Way Outgathered in Barcelona to discuss the evolution of multicellularity. It is yet another challenging topic because it contradicts the evolutionary model. The most obvious contradiction is that it requires a series profoundly sophisticated enhancements and changes to occur in a population of unicellular organisms. Such changes are unlikely to occur spontaneously and the evolutionary narrative inevitably relies on moves that are reminiscent of the proverbial “And then a miracle occurs.” As one paper admitted:
The emergence of multicellular animals or metazoans from their single-celled ancestors is one of the most important evolutionary transitions in the history of life. However, little is known about how this transition took place.
Indeed. Little is known about how multicellularity evolved simply because it is not plausible to begin with. The result is vague speculation that sometimes looks more like just-so stories than scientific hypotheses:
We have proposed that the evolution of soma involved the co-option of ancestral life-history genes whose expression was conditioned on environmental cues (as an adaptive strategy to enhance survival at an immediate cost to reproduction), through shifting their expression from a temporal/ environmentally-induced into a spatial/ developmental context.
Of course evolutionists must believe that it occurred—someway, somehow. And in typical fashion, even if evolutionists cannot explain how something evolved, at least they can provide the usual fitness rationale and draw up the usual evolutionary trees depicting when it evolved and how it propagated along the evolutionary tree according to evolution’s pattern of common descent.
Unfortunately for evolutionists this exercise usually frustrates the theory as the various biological wonders inevitably do not follow the pattern of common descent, but instead arise independently more than once.
That is nowhere more true than with the miracle of multicellularity which, if evolution is true, must have independently evolved more than, err, twenty-five times.
Evolution not only is apparently quite good at constructing biological wonders, it does it over, and over, and over again.
The theory is saved, however, because we know it is a fact.
