Can you give me an example of an organism that has changed where its environment has not changed at all?
Here.
Thanks you have just proven my point. An unchanging environment where bacteria are increasing in fitness.
You really should learn to read a bit better.
What you might also want to take into account that the ONLY non changing environment is of the sort the article is an example of: AN ARTIFICIAL one!!
Because in nature there is no unchanging environment.
I get the feeling that you won't get this, but you have made a complete arse of yourself. You add another example of my theory that Americans have deficiencies in thinking. You are a victim of the Twinkie diet.
Note, first, that thedoc asked: "Can you give me an example of an organism that has changed where its environment has not changed at all?" He didn't specify whether the environment was
natural or
artificial, now did he?
But why do you think they carried out this experiment in the first place? Because, in fact,
there are natural environments that are stable and unchanging over long periods of time. Here is what Richard Dawkins wrote about this in The Blind Watchmaker:
If the conditions in which a lineage of animals lives remain constant; say it is dry and hot and has been so without a break for 100 generations, evolution in that lineage is likely to come to a halt, at least as far as adaptations to temperatures and humidity are concerned. The animals will become as well fitted as they can be to local conditions. This doesn't mean that they couldn't be completely redesigned to be even better. It does mean that they can't improve themselves by any small (and therefore likely) evolutionary step: none of their immediate neighbors in the local equivalents of 'biomorph space' would do any better.
The experiment conducted with bacteria appears to show that Dawkins was
wrong about there being no further evolutionary changes in a stable environment, but that's beside the point for the purpose of this reply to you. As everyone can now see, YOU are wrong in stating that there are no
natural unchanging environments!
Why don't you email Dawkins and insult him, instead of me?
You have made an utter fool of yourself. No doubt not the first time.
