That's not quite what it says. What is says is that mutation RATES are low, not mutation NUMBERS. And it only says that mutation ALONE doesn't have much of an effect, because mutation needs a selective factor (such as natural selection) in order to result in significant changes at a population level.
Can you explain that please?
Mutation rates are low = The
number of mutations occurring... to my understanding. It's not the speed of the mutation.
If you can't define it, then how can you claim they are rare?
Define what? A mutation? You didn't ask me to define a mutation. You asked me "what
a mutation that is useful on the macro level would look like".
So what would you class as a non-micro mutation? And what prevents micro mutations from adding up to large changes (as they have been observed to do)?
Non micro mutation?
Mutations occur. We know this. The article I linked says.
The only mutations that matter to large-scale evolution are those that can be passed on to offspring. These occur in reproductive cells like eggs and sperm... called germ line mutations.
The article gave examples.
From these examples, an ear, an eye, a nose,... etc, may be altered, as is
shown with the cat's ear curling.
Another example, is like building a resistance, like for example, the immune system building up a stronger defense system.
The article says nothing about mutations adding up to produce anything. Rather it says this...
There are some sorts of changes that a single mutation, or even a lot of mutations, could not cause. Neither mutations nor wishful thinking will make pigs have wings; only pop culture could have created Teenage Mutant Ninja Turtles — mutations could not have done it.
Why am I answering all your questions, and you are refusing to answer any of mine?
I'll try again.
Is there anyone who can define any mutation that can be useful on the macro level?
That's okay. As long as there is mutual understanding that mutations are not rare in the sense that they do occur every time a living thing reproduces.
That still depends. Since,
mutations are random. They don't choose
where they happen. So no one can say they are occurring all the time where it really matters.
The article also said...
Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.
If it doesn't occur in the reproductive cells, they don't matter at all - keeping in mind, my focus is on the major level of modification.
