Evolutionists have discussed a wide variety of mechanisms to produce the biological change their theory requires. Horizontal gene transfer, cell fusions, directed mutations and domain shuffling are some of the more exotic mechanisms to go along with the more traditional mechanisms such as genetic mutations. But these mechanisms were not available in that warm little pond (or deep sea vent, or comet hurtling toward earth, or ...) where evolution got its start. The very mechanisms of evolution had to have, at some point, evolved. You can read more about this here and here. We now hear evolutionists speaking of "the evolution of evolvability," and "preprogrammed evolution." Simply put, evolution had to have created evolution. Does this make sense?

Evolutionists see no problem with their idea that evolution creates evolution. As one evolutionist rhetorically explained, "Does fire create fire?" Indeed, fire certainly does create fire. Does this resolve the problem that evolution must have created evolution?

New research shows that in the span of just fifty years songbirds have become slightly smaller, probably as a consequence of global warming. This is no big surprise as it has long been understood that size is inversely correlated with temperature. The Darwin contemporary Christian Bergmann first observed this trend, in terms of a correlation with latitude, and the trend became known as Bergmann's Rule. But how did the change come about?

The new research, which accounts for more than 100 species and almost half a million birds, shows a rapid reduction in size as the earth warmed in recent decades. The change is slight, but the statistics in the massive study are undeniable.

Perhaps the change is a consequence of natural selection shifting the populations to slightly smaller sizes, as the smaller individuals have greater reproductive success. Or perhaps the change is a result of built-in biological responses to the temperature change.

However the changes arose, the process involved complex structures and mechanisms--structures and mechanisms that must have evolved if the theory of evolution is true. Under evolution, we must believe that not only have the world's species evolved, but their various response mechanisms have as well.

Evolutionists explain that evolution happened to construct such response mechanisms. When needed those mechanisms were helpful, and so were selected for.
