Hardly. There's a lot of room at the bottom. A phrase still as true today
as it was half a century ago!

What's insane is people still think this stuff was created in the snap of
some magic finger.

It is an impressive anination of the the copying and transfer of DNA is
actually occurring at a molecular level inside every cell. Thanks for
sharing. It is a shame that you cannot be bothered to understand it.

Asking him to understand it is trifle unreasonable - he hasn't got the education on which an understanding might be built. And while we can probably understand the transcription from DNA to messenger RNA (which is presumably what was being animated) the business of getting from there to protein synthesis is trickier.

It is worth watching to the end. It does show mRNA being created and
then follows it to the next stage where it is read and the protein being
formed by amino acids.

It's a peptide chain at that point. Not many proteins are formed of just
one, so when transcription of the assorted bits is done, still "some
assembly is required".

It also shows the intricacy of the DNA replication process. I hadn't
realised that whilst one half of the strand can be copied without any
difficulty the other has to be copied by skipping along a loop and then
working backwards. The molecular machinery has a preferred direction.

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.

The current general opinion is that the RNA world emerged first, and only
later did the DNA world to emerge. The problem with RNA as a genetic store is
that it is too error-prone, sharply limiting how big and fancy a critter can
be. DNA removed that limitation.

Very interesting video.

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.

The very first step is probably something like an RNA molecule that can
copy itself or catalyse the formation of its own components. Things can
bootstrap up from there given geological timescales. The exact details
are still unclear but plenty of people are working on the problem.

It builds us too, but that's a detail.

Eventually. Given about 4.5bn years of evolution.

He didn't say that. He probably does know enough to know where to look to find out exactly what is going on, and enough to know that it would take a while.

Nothing crazy about it. That's what random variation plus selection can manage.

So what? Three billion base pairs is already quite a few zeros.

Actually, that's exactly what it did.

A famous fallacy. Each stage of development has to work, but the successive evolutionary steps can follow any path that works.

Eventually. Haekel said that ontogeny recapitulates phylogeny

https://en.wikipedia.org/wiki/Recapitulation_theory

which happens to be wrong, but in an educational way.

> It builds us too, but that's a detail.

But important to us, at the moment. We clearly need intelligent redesign.

I've read several books lately about evolution at the biochemical
level. There's a lot of hand waving about the initial origins of life,
the accident in the conjectured primordial soup thing. Some math
analysies put the probability of that happening, anywhere in the
universe any time in the past 12 billion years, so close to zero it
would be tiring to type all the digits.

The great mysteries are the origin of the universe, the origin of
life, and consciousness. So far we are clueless about all three.

Cell and molecular biology is fascinating... At one time in my youth
I thought I wanted to be a biologist. I haven't kept up at all with the
subject. Anyone know of some good books?

I found this list,

Then you will have heard of RNA-world.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3331698/

We can haggle about whether life first got started in the proximity of
deep water smokers or in a tepid pool somewhere. Self organising redox
chemical reactions are very rare but not completely unknown in inorganic
chemistry. It isn't that much of a stretch for a particular sequence to
occur once that can then take over. RNA instability pretty much
guarantees that it will evolve to become better or vanish without trace.


Some math
analysies put the probability of that happening, anywhere in the
universe any time in the past 12 billion years, so close to zero it
would be tiring to type all the digits.

Usually such "analyses" are done by Young Earth Creationists with their
own huge axes to grind.
The great mysteries are the origin of the universe, the origin of
life, and consciousness. So far we are clueless about all three.

We are not too bad on the origin of the universe. Big bang cosmology
works right back to the first 10^-43s or so when physics breaks down.

Biologists are making huge progress with the origin of life. Sequencing
entire genomes for species has become almost routine today.

Synthesising designer DNA from scratch is already possible.

Consciousness is the most elusive of the three to pin down. I am
inclined to believe that it is an emergent behaviour in a sufficiently
complex network of computational elements. Time will tell - computer
simulations of the brain are getting closer to being able to match a
human and if Moore's law holds for another decade or so will get there.

The most recent attempt I am aware of simulated 1s of 1% of a human
brain and took 40 minutes to do it on one of the top supercomputers.
They are still about 100x short on capacity and 2400x too slow.

https://www.telegraph.co.uk/technology/10567942/Supercomputer-models-one-second-of-human-brain-activity.html

Science progresses by experimenting with nature to see how and why it
works. You seek to invoke magyck that merely pushes back the problem to
the next layer of the onion with "who designed the designer?".

There's only one force in the universe powerful enough to construct
something that complex: evolution. One must either believe that, or believe
that there is something impossibly wrong with all known laws of physics*.

proven.)

between our retina and our brains.
