From their side: "those funny humans were sending a lot of clear

It depends a bit on how hard line you want to be. They don't do quite a
few of the things we normally describe as life until they infect a host
cell and manipulate its genome to reproduce. Even then they subvert the
cell to do these things they do not have their own metabolism as such.

In a strict sense they don't fit the usual definition of "Life".

The fact that they usurp a host cell to do these things doesn't mean
they aren't happening. Viruses are parasitic and like many parasites
they can not complete their life cycle without infecting the host.

But where do you draw the line? Are incorrectly folded protein
autocatalytic infectious agents like prions which cause scrapie in
sheep, CDJ and the insidious nvCJD aka BSE "alive". They need a host to
survive but are to all intents and purposes a catalyst that converts a

This is insane. This is impossible.

Yes, but that is how it works. It took some billions of
years for all that organized complexity to evolve, one
trick at a time.

But it couldn't evolve one bit at a time. If it doesn't all
work, none of it works. And it builds every bit of itself.

Sure it can. Very slowly, with lots of mistakes made and then
erased. Not an efficient process at all. But it does not need
to be.

But each incremental step must be an improvement or it won't be
selected. So how can evolution build an immensely complex
system, where all the pieces have to be working before any of it
it can work (and reproduce itself) ?

No. It doesn't. You are putting arbitrary constraints on what
evolution can and cannot do. Evolution has explored many weird dead
ends as well.

Sorry, your ideas aren't in line with reality. While any given trait
or even species can die out, when it formed and spread through a
population it provided an advantage or at least offered no
substantial liability. While a trait can spread through a population
over time even without being of much benefit, if it is a liability it
will be selected out.

It is you who fail to understand the meaning of "fittest". It does not
mean the global optimum of efficiency. If it did then nature would have
already fixed the defects in photosynthesis. It means gets to reproduce
and form a gradually increasing proportion of the population.

If the system is resource constrained then "fittest" pretty much is
determined by ability to get enough food, not get predated and find a
mate. This usually leads to comparatively simple camouflage.

But in the tropics particularly where the system is not resource limited
and food is abundant there is scope for more complex behaviour with what
are essentially arbitrary preferences of the usually drab female birds
being selected for in the males. These include bright colours, silly
tail feathers, collecting pretty things and beautiful songs.

The male peacocks tail and brilliant blue colour is a pretty good
example. If you think that 6' tail helps it to fly then you must be
completely mad! But without one he will never get a mate...

It is self limiting in that the ones that have tails too heavy to fly
cannot evade snakes or go up into the trees to proclaim their patch.

Amazingly they can fly just about gaining about 10' each time climbing a
tree from branch to branch until they are high enough to make their big
screeching call. First time I saw one I though it was a bin bag!
It basically spans the space of life forms and if there is a niche
with no competition eventually something will evolve to exploit
it.

Another assumption on your part. There is nothing to say all niches
will be populated. The basic increment of evolution is random
changes. Since they are indeed random that does not mean all will be
explored. There is also the fact that for many significant features
multiple traits had to develop before they became significant. So
while waiting for one change to develop and spread through a
population another change may die out.

If there is no competition for the niche then something will eventually
exploit it. Put another way with the same constraints and boundary
conditions approximately the same physical solution has been found more
than once by entirely different plants and animals isolated from each other.

Most recently in the news the flightless rail bird has re-evolved about
140ky after it was last known. Same environment same constraints without
ground predators on an isolated island. It is out of luck too since it
will probably go extinct again due to sea level rise.

https://www.msn.com/en-gb/news/environment/bird-that-went-extinct-136000-years-ago-comes-back-from-the-dead-after-evolving-again/ar-AABbnvo
A change that is beneficial, neutral or only slightly detrimental
to individual survival can persist. Sickle cell anaemia is one such
example - not optimum for the individual but it confers some
immunity to deadly malaria not found in those of us with more
normal blood cells.

https://www.newscientist.com/article/dn20450-how-sickle-cell-carriers-fend-off-malaria/


This does not prove your point.

It exactly proves my point. You fail to understand.

Where malaria is prevalent sickle
cells provide a benefit and so are established in the population.
They are spread more widely only recently since man's other
evolutionary changes have made transportation widespread. Give it a
few thousand generations and it most likely will be selected out.

It doesn't cause enough harm to die out though. And at present we are
still struggling with getting malaria beaten so it may never die out.

The requirement for a novel trait to establish in the population is
for the first person with that novel feature to survive and
reproduce (and for their offspring to be fertile).

And likewise for most subsequent carriers of that trait.

Nature can be very capricious. There are plenty of female spiders that
eat their mate immediately after sex (or before if the males courtship
dance isn't up to snuff). It has evolutionary advantage for the species
(though it is a bit tough on individual males).

I think you are being rather arbitrary about judging viruses. There are numerous bacteria which do very little or nothing at all in a spore state. It is only when they are in a hospitable environment that they "come alive" and begin to reproduce. Same with many plant seeds.

Your point seems to fixate on the fact that the virus requires a host not just as food, but the means of reproduction. I don't see where that makes it any less alive. It reproduces, has motion, feeds and most importantly - the one essential thing left out of MRS GREN - mutates to allow for evolution.

In fact, that they reproduce in very large numbers and depend on mutation for their ability to survive clearly shows how well evolution provides for adaptation and survival enhancement. JL can't understand how replicating DNA could have evolved, but is that really so much more complex than resistance to medication which can happen relatively quickly to most evolution. It demonstrates the power of natural selection combined with mutation.


The fact that they usurp a host cell to do these things doesn't mean

I'm not aware that they have definitively shown scrapie is caused by prions.. But even if so, that lacks every other aspect of live other than reproduction.


They were given the opportunity in the UK to spread like wildfire
because someone thought that ground up abattoir waste would make a very

Like here in the US? We only stopped using mechanically separated beef in 2004. This contains parts of the spinal cord and ganglia which might spread BSE as well as actual brain tissue does. We just got lucky.

That is simply not true. For example, there are no creatures that absorb cosmic rays as their food source. Perhaps and extreme case, but it illustrates that not all niches can be filled. Evolution has to take a path of consistent survival. If there is no way to bridge a gap, a niche on the other side can't be filled.

It has been less than 100 years since we have been able to battle malaria? So in Africa the pressure has been for the gene to remain. Give it a few thousand generations and see if the gene is still around. Also consider that sickle cell anemia is does not strongly prevent reproduction with an average age of death in the 40's.

What has always amazed me is the creationists' ability to claim
simultaneously that natural processes are not enough to create something
as complex as life, but seeing no problem with the existence of an
infinitely more complex entity that needs to be brought as a basis for
an "alternative explanation". In other words, life is too complex to
be created "by accident". Gods apparently aren't.

OK, evolution theory is wrong, genetics is a random fluke that happens
to work by pure accident, be that as it may. So now let's talk about a
credible theory of theogenesis...

What amazes me, or sadly doesn't much any more, it that the only ideas
that most people have, about possible alternates to primordial soup on
Earth, accidentally creating RNA which accidentally invented and
programmed DNA, is to scream "creationist!"

Of course, it's probably impossible to make or use DNA without already
having all the cellular machinery in place to support DNA, which is
all created by DNA.

OK, evolution theory is wrong, genetics is a random fluke that happens
to work by pure accident, be that as it may. So now let's talk about a

Yeah, sadly science has now become political.
This was in the Nat. Rev. today,
https://www.nationalreview.com/2019/05/evolutionary-theory-crowning-achievement-western-civilization/
(nothing new)

I took a seminar in college called the "origin of life".
Interesting to me... but there are not any new ideas since
then... AFAICT.

We need to find other types of life to give us new ideas...
But if it started on Earth, then I think we're stuck with it
coming out of the primordial soup somehow.

Why would life arrive here as spores? Why not robotic spaceships with
chem labs, to cook up something appropriate on the spot?

We've had electricity for a couple of centuries and electronics for
around 100 years, and we're just starting to understand our own
chemistry. What could some ancient civilization do in 10,000, or a
million years? Build a few billion AI robotic chem labs?

It's very probable. At least as good as the soup thing.

All that has done is punted the problem from /here/
to /there/. None of the interesting questions are
addressed let alone answered!

Well the interesting questions are way beyond our knowledge (yet?...).

Evolution as we know it since Darwin can be designed into life by a
creator or life can have occurred spuriously and then evolved etc.,
that much we can ask. Of course if a creator has created life who
created the creator is the obvious next question, not sure if
it counts as one of the "interesting" ones :).

And that superbly complex cellular mechanism, so nicely visualized
in the video John posted (mesmerizing to just look at) has come
into being.... how? Spuriously, by sheer chance? Does not look like it,
I would think it is no more statistically probable than say stable
nuclei to go into a chain reaction. OTOH given enough time who knows...
Then if a creator made it - again, who designed the creator.

Like you say, the best answers to that we have is "we don't know".
Neither do we know if we can possibly know these answers.

So, is this a chicken-egg argument, that you label 'impossible'
rather than admit it's just complicated?

DNA can be used to store books and videos, by building it without
'cellular machinery', i.e. in a laboratory. It's make-able, and use-able,
and no 'probably' about either. Yet, you are comfortable saying 'probably impossible'.

Another assumption on your part. There is nothing to say all niches
will be populated.

If there is no competition for the niche then something will eventually
exploit it.

That is simply not true. For example, there are no creatures that absorb cosmic rays as their food source.

Nothing about these statements is 'simple'.

It's not so much 'untrue' as 'undecidable'. The biosphere, after all, DOES absorb
cosmic rays, and DOES require genetic variation, which comes (in part) from those
cosmic rays. Is a biosphere a 'creature'? Is absorption and utility evidence
that the radiation is 'as food'?

The 'niche' concept is similarly
ambiguous: who is to say what DOES constitute a niche? Is absence of an
occupant a temporary condition, or evidence that the ''niche' is nonexistent?

It's like arguing whether a policy is 'reasonable': some folk say it is, if
they aren't outraged by the policy statement, while others are sure it
is ONLY if a cogent logical treatment of causes and effects supports it.
A third view, is that a person in a discussion can be 'reaasonale' if and
only if he/she reacts to reasoned expressions, and no policy can do that.

Maybe he is right. But then he must accept that the creator
does require a creator too. By exactly the same reasoning.

The only intellectually honest way to leave this infinite loop is not to
enter it at all.

Well, no. Feynman's famous essay from 60 years ago is memorable, but
atoms are the same size now as they were then. In 1959 you could do
litho with a crayon, and today folks making feature sizes of ~10 lattice
constants of silicon in the lab and ~15 in production.

So not so much room remaining, really.

Because approaching it in a way significantly different than extreme
reductionism requires some act of creation. By a deity or your robotic
AI labs or the biker mice from Mars. Fine, but then the onus of
explaining them is on you.

We may never know the origin of the high-temperature superconductivity
as well. So what? Should we give up and not even try to find it out?
