have speculated on the evolution of the lung. You might disagree with the
mechanism and the evidence or reasoning. But you should not make a
statement which can so easily be disproven 2) You seem to be under the
impression that intermediate steps are disfunctional. I'd suggest that the
problems lie far more with your arguments than with evolution. Why would an
intermediate lung not work ?

You say that I am so easily disproven, and yet you have no proof! Please
show us what these people have speculated so we can comment on it. The
reason why an intermediate lung would not work is that the whole breathing
system has to work perfectly or the animal will die. Unless each step in
the evolutionary process is a large one involving the entire system, it
can't work. This is not normal evolution, in fact it would seem like a
miracle. Please show us how an intermediate step could be funtional, or
show how my arguments are faulted, instead of just saying so with no basis
for your statements.

>Perhaps I should first hear the 'arguments' behind your strawman. Please
explain why a lung required a 'hole' in the lung. Your argument is one that
might be reasonable but you have failed to show that the lung would have to
be punctured. If your argument is that I do not understand all the steps
fully, then you have a point. But all this does is show lack in my
understanding of the mechanisms involved. Does this mean that therefor
evolution is impossible or that evolution of the lung is impossible ? Of
course not.

Ok, this one isn't to difficult. In an animal lung has only one hole, that
it breathes in and out of, and a bird breathes in one hole and out another!
That mean that somewhere along the way it must get an extra hole!

>You have come up with the unsupported argument that evolution of the lung
would necessitate a puncturing of the lung. Perhaps you should make an
effort to support this ? Is puncturing of the lung required ?

If you need another hole, then I guess you have to puncture it.....

is possible only on a very limited scale. Please explain ? And why should
evolution of small scales not eventually become evolution of larger scales
? What mechanism(s) prevent this ? Furthermore there are very conclusive
data that evolution happened. The question remains, what mechanism was
involved.

I don't think the data overwhelmingly shows that evolution took place on a
large scale. The mechanisms that make small scale changes have only been
seen to make small scale changes, therefore we can't conclude they also
made large scale changes, and, to my knowledge, it is not possible to for
these mechanisms to make large scale changes. If you think otherwise, then
please show us how this works.

life forms we know today. Genetic data show support for the observations in
the fossils. So indeed, the data is there and it is undeniable that it
happened, the question remains, how did it happen.

The data may show that at one stage there were simple creatures, and now
there are complex creatures, but it does not show how it happened. There is
nothing there that shows that they evolved, only that there are different
types of creatures now than then, it could equally mean that God created
the animals slowly, putting animals here in steps. This is only evidence if
you already assume evolution to be true.
