| RockSmith372 said: Single celled organisms that exist today are not suppose to be simple. They have been evolving almost 4 billion years in environment of harsh competitions. Bacteria are one of the most adaptable organisms on earth and can survive pH levels from 1-14 and temperatures from the vents of lava in the ocean to the top of the Himalayas. Now the probability of a simple self replicating chemical reaction is fairly slim. After that, the suitest molecule would be the one that replicates the quickest. Eventually those molecules would absorb from other replicating molecules in order to replicate quicker. This was the first competition against other reactions. Some absorbed other molecules and replicated while others found protection through lipid layers(which in water encloses like a bubble) which protected the molecules. This was the first cell. It was very basic. |
From the article: "The energy metabolism takes place in the so-called powerhouses of the cell, the mitochondria. They transduce the energy taken up as food into adenosine triphosphate, in short ATP, which is the universal energy currency of life. A chain of five complicated molecular machines in the mitochondrial membrane are responsible for the energy conversion."
Every living cell known to man requires these "complicated molecular machines" as much as water. Now I am like you that by faith believes there is life that doesn't require these machines. For life comes only from life. So far man hasn't seen any case where life didn't come from life.
It's a no brainer today that we know life is not simple including bacteria because of hindsight but people back in Darwin's day did, in fact, did see life (cells) as something very simple. Hindsight is always 20/20.
