Please enlighten me on how you have tested natural selection acting on a random mutation which results in an organism having increased fitness? I think the joke is on you.
Mutation doesn't mean increased fitness; the mutation could have an adverse effect on the organism but through the process of natural selection those that are capable of surviving to reproduce are the organism.
Taking 3 seconds to research would answer this question. You can test evolution with bacteria, fruit flies, or any organism that goes through generations rapidly. On top of the fossil record that confirms the theory makes for a compelling case especially when compared to the "god dunnit" crowd.
Next time do a bit of research before next time you think of wasting my time with facile questions.
Mutations do produce fitness according to the theory or your theory of evolution is dead on arrival. Somehow you are of the crowd that believes that only neutral or beneficial mutations get passed on and we know by the numbers that this is not true. 6,000 genetic disorders and counting. How many beneficial mutations can you point out ? I am willing to bet just a few.
The mutation could have an adverse effect on the organism ? I know for a fact in most cases it has an adverse condition on the organism. I worked in a research lab for over 11 years studying mutations and cells. The majority of flies that showed any change at all were deformed and all flies suffered a shorter life span. The only flies that showed any kind of trait changes over a few generations those traits were lost and the flies reverted back to the origional traits.
I suggest you do some research before you call someone else out. Start with the conditions needed for mutation fixation. I pointed out nine conditions needed for mutation fixation to happen then how these conditions are impossible to be met. So let me suggest since you like Google to google mutation fixation and you will find several articles on it and why it is needed for evolution to happen.
There is nothing compelling about the theory unless you care for conjecture and vivid imaginations. Just about anything you can throw out there has been already dealt with within this thread. You can borrow your buddies copy and paste jobs because all you are doing is regurgitatiing what they have already pasted. Not meaning to be short but I don't like attitude from Ideologues.
