The cell responds to "stressors." The stressors may be random, but the cell's response is not. For example, cosmic radiation is presumed to strike cells randomly, some mutate as a result and most of the mutations are lethal, but some are not. Those that survive, reproduce and they in turn may also mutate and survive to reproduce, and so it goes on and on. Eventually, the end result may somewhat removed from the original progenitor cell. And that's just in response to one of a whole slew of stressors in the cell's environment.
From the cell's point of view it is to adapt to the stressors in the environment and those which survive are accomplishing that goal by using the information derived from the stressors.
[The cell responds to “stressors.” The stressors may be random, but the cell’s response is not.]
Granted, some cells are coded to indeed respond to stressors, and infact to switch functions sometimes, however, it’s clear that many cels don’t- cells which would have been necessary to change in order for hte next higher form of life to evolve. As well, I again must point out that the coding that allows cells to adapt and survive, must have coem from somwhere, and one should ask where? If a cell doesn’t have the necessary info to begin with, it will not be able to adjust and survive- One must also take into concideration that the amount of changes in higher in higher lifeforms is simply staggering- simply too much to account for the cause being random mutations and environmental stresses. Most of the cells present in differing species don’t change according to stressors.
I can see where you’re going with htis, and yes, it’s a hypothesis that does make soem sense incertain cases, but I’m afraid I have to dissagree with the premise
This is a true explanation of evolution of species if and only if all information regarding the construction of an offspring is contained in DNA coding. This is not establlished. In addition your statement “most of the mutations are lethal, but some are not” is inexact from a mathematical standpoint. The real numbers reflect a statement more like, “ mutations resulting in significant differences that do not actually kill the offspring are astronomically unlikely, while some trivial modifications do occur very rarely.”
Before you begin the infinite monkeys argument please be aware that I am aware that the time allotted for mutation to play its species game is 1 billion years more or less from the Cambrian explosion until now. Not much time at all for a stepwise approach to making a behemoth out of a multicelled bug.
