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:
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.”
