Science has shown how naive the long-held assumption of “simple bacteria” is. Indeed, there is nothing simple about these tiny prokaryotes.
For example, two German scientists said in regard to intracellular signaling in bacteria:
"Despite the apparent simplicity of the basic signaling mechanisms, signal processing in bacteria can show a large degree of complexity. The magnitude of internal and external stimuli means that behavioral decisions must involve cross-regulation between individual sensory systems. At the same time, individual signals have to be insulated against unspecific cross talk to preserve the specificity of input-output relations." (Kentner, 2011)
In the face of such enormous complexity, secular scientists must engage in “just-so” accounts of its origins. In regard to how bacteria respond to the vast assortment of environmental signals, six evolutionists said, “A wide range of signal perception modes have evolved.” (Krell, 2010) This explains nothing. Neither does stating that membrane pores (channels) in microbes “have evolved to be usually closed (in an occluded conformation).” (Kung, 2010) Scientists have never observed signal perception modes “evolving” or membrane channels “evolving” to be usually closed. Creationists maintain that the detailed conditions required for their very existence (life) were created “in the beginning.”
