Rarely devious, I was here, this is a "trick question"
Rarely devious, I was here, this is a "trick question".
Cytochrome C was one of the first examples of what some evolutionary molecular biologists came to refer to as a "molecular clock". In 1963 Margoliash famously wrote;
"It appears that the number of residue differences between cytochrome C of any two species is mostly conditioned by the time elapsed since the lines of evolution leading to these two species originally diverged. If this is correct, the cytochrome c of all mammals should be equally different from the cytochrome c of all birds. Since fish diverges from the main stem of vertebrate evolution earlier than either birds or mammals, the cytochrome c of both mammals and birds should be equally different from the cytochrome c of fish. Similarly, all vertebrate cytochrome c should be equally different from the yeast protein."
And so was born the idea among evolutionary biologists of NEUTRAL! mutations, occurring with clocklike regularity and having apparently no discernable affect on the phenotype pro or con!!!!!!!!
Well how now brown cow can that ever square with mainstream Neo-Darwinism I would ask????????!!!!!!!!!
And where is God in all of this anyway?
I'm no expert on bacterial DNA sequences, but are you sure? Have you sampled all the available bacteria on the planet? The claim may be entirely correct, I do not know, but if so that points to one big lacune in our knowledge base, but I'm not sure it points to much else.
ETA: There are two obvious explanations if that observation is correct. One is that we simply haven't looked at enough bacterial species and certainly not the one from which mitochondria were derived. The other is that the 'intermediate forms' no longer exist and are lost to time. A third possible explanation is that it's all just magic, but that isn't very satisfying.
