Hi Guys,

I guess this is more of whimsical posturing rather than a question.
But I have just finished reading a chapter of my textbook
(Microbiology:Principes and Explorations: Jacquelyn Black) which goes
into some depth to explain Prokaryotic and Eukaryotic cell structure
and I am completely blown away with what i've read.

I guess what has struck me as just absolutely amazing is how ingenious
and perfectly designed these cells are. It really is a masterpeice and
I find myself asking the question as to how these cells and their
designs came about.

Now to add the caveat that I am not religious and that I don't seek
this to become a question of the universe thread but i'm just having
trouble reconcilling just how these cells originally came about.

Could someone please point me to a theory of how, I guess the building
blocks of humans started ie evolution or the opposing theories etc???

Microbiology just never ceases to amaze me, you think your studying a
fairly well defined subject but it just keeps raising questions. In my
mind anyway :)

Best Regards

HI Griffith

Your amazment is a experience I think most biologists have atleast once in
their existence.

Reality, the living world , its origions and mechanisms of creation are
awsome  targets for thought.

HAve you read  Philip Dawkins "The blind watchmaker", I think you would find
it interesting

At the risk of bandwith I  include a couple of quotes from that work ;

"In crossing a heath, suppose I pitched my foot against a stone, and were
asked how the stone came to be there; I might possibly answer, that, for
anything I knew to the contrary, it had lain there forever: nor would it
perhaps be very easy to show the absurdity of this answer. But suppose I had
found a watch upon the ground, and it should be inquired how the watch
happened to be in that place; I should hardly think of the answer I had
before given, that for anything I knew, the watch might have always been
there."

"We have seen that living things are too improbable and too beautifully
'designed' to have come into existence by chance. How, then, did they come
into existence? The answer, Darwin's answer, is by gradual, step- by-step
transformations from simple beginnings, from primordial entities
sufficiently simple to have come into existence by chance. Each successive
change in the gradual evolutionary process was simple enough, relative to
its predecessor, to have arisen by chance. But the whole sequence of
cumulative steps constitutes anything but a chance process, when you
consider the complexity of the final end-product relative to the original
starting point. The cumulative process is directed by nonrandom survival."

Hello,
        Just a quick note... The book "The blind watchmaker: why evidence
of evolution reveals a universe without design" is written by Richard
Dawkins.
