I think location greatly affects speed of evolution. Like
right on the coast offers creatures 3 very different
potential evolutionary pathways- stay on coast, sea, or
land. Or a rainforest or coral reef. Probably the most
important environmental input for a living thing affecting
its fitness.. is all the other living things. So when one
thing gets more complex (more sophisticated predator maybe)
the fitness criteria for all other living things it affects
also becomes more complex. Maybe the burgess shale just
happened to be a 'rainforest'y location. Or maybe if genes
are legos that can attach 1 other piece, to simplify, maybe
another piece evolved that can attach 3 pieces or something,
thus making more combinations.

Yeah I think that's definitely true, lifeforms seem to adapt
to complexity via random mutation, whatever is an
advantageous mutation to the situation is spread, whatever
no longer works disappears via environmental
changes/predation. Something as simple a small cluster of
light detecting cells on your back can mean the difference
between life or death. Suddenly detect a shadow blocking the
light on your back, move quickly!

I love prehistoric life/paleobiology so I'm really glad to
find this. Will check it out when I get home from work!

I know what you mean about wanting to go back in time to see
what things really looked like (vs. just their impressions
left in fossils). It still blows my mind to think that
megafauna like dinosaurs or some ice age mammals actually
walked the earth... (to say nothing of all the smaller
creatures that came about from the Cambrian era) Amazing.

yes please listen its really interesting the guests are very
knowledgeable in this one.

Yeah whats really interesting is how a lot of these animals
existed for tens of millions of years but infact represent
evolutionary dead ends, they have no decedents, they
couldn't adapt fast enough to changes, or were superseded by
a more efficient animal. I mean I don't think our fate as a
species is any different, on geological times scale we
barely exist

there are so many lush things to listen to on the Beeb site
like that, wish i had the time to get thru em, will check
this one out tho.. (there's a REALLY good one on EVP
recently, i think it's on the 'Seriously' one...?)
How the fuck did DNA come about anyway? Is that evolving too
or is it like a runtime thing that doesn't change? I used to
just stare at my hands and think about how they came about
until I felt quite strange, fun.

yeah its very strange if you think about it, we are
topologically the same as a nematode worm, a torus shape
with a mouth and an anus. What I find freak is how we have
fractal fingers bodily symmetry

Also, I think i read somewhere that there are occaisonally
big leaps that they can't really account for with mutation
just pootering along.. that's quite fascinating.

yeah that's what the Cambrian explosion was in essences,
just simple life forms and suddenly in a short time scale
geological, multitudinous lifeforms sprang forth, what
caused it is a matter of great debate

you can see that with simpler life forms like sea slugs and
sea cucumbers that don't have a brain as such just large
ganglions and collections of neurons that enable them to
feed and do other actions but not necessarily think

complicated watch gears used to be the best metaphor for
whatever the universe is or is doing, now computers. so just
like convergent evolution re-invents wings/eyes
independently, computer programs maybe re-invent whatever
the universe is doing. So i don't get how the universe can
calculate so much. if i rotate one thing about another thing
in 3d space, i have to program to 'rotate about z to get in
the correct z plane, rotate about y to get in the correct y
plane, do the desired rotation, unrotate y, unrotate z' (i
might have remembered it slightly wrong). But the universe
has zillions of planets rotating, not to mention zillions of
grains of sand/dirt on each planet, and it's like voxel
geometry so it is calculating all the stuff inside
the surface of a planet as well, not just external mario 64
surface polygons.
Maybe it doesn't do rotation algorithms since that'd lag, or
maybe each 'tick' of the program takes zillions of 'years',
we just don't feel it because our brains only update on the
next program tick. maybe everything merely calculates
immediately locally like a cellular automata, even sight is
your eyes interacting with immediately local photons.
gravity spooky action at a distance is tricky but maybe
doing same. or instead of moon rotating around earth, it's
just 'moon moves in straight line (object in motion stays)'
AND 'tug slightly in straight line to earth as gravity'. So
2 straight lines each tick can simulate rotation for more
efficiency.

Yeah I think this is one of the most fundamental questions
of physics, what is the information density?

is there a locality to this sort of thing, i.e. are things
only rendered when there is an observer, when there is no
obsereve effect is it just in some probabalistic state, Are
we thinking in too simplistic terms to describe what is
actually going on?

I was thinking of the ethics involved in future games,
imagine you had a game like sim city full of actualised
Artificial intelligences would it be ethical to send in a
Godzilla creature to destroy their town for a bit of fun,
dare you turn of your computer? would it be ethical to do
so?

Oh yeah I was going to write but forgot. Like you can get on
the ground and see all these complicated insects. a flea
even has its own mite parasites, i wonder what is the
longest chain of that, i know one whale in a documentary had
actual normal crabs as parasites around its eye, maybe those
crabs have parasites that have parasites, gets to a single
cell soon i guess, a chicken egg is a huge single cell. well
maybe the universe simply doesn't compute that stuff unless
someone looks at it. then again you can watch a bug move,
look away, look back and it didn't pause, it's further
along.. but maybe something else was watching it.

That's a weird thought, like the bug didn't actually move,
my brain was just edited to think it moved..

actually I figured out the most likely scenario, occam's
razor or whatever... why update all this complicated reality
made of zillions of atoms/quarks calculations etc... when
you can instead simply update the mind. Astronomically way
more efficient. Only things you observe or think about need
to be calculated. Distant planets? They're compressed to
vague blurry concepts of any information you're seen or read
about them. It's all memes. The universe is just memes in
your brain. I'ma call this "w M w's razor". The only other
"razor" that exists. Nothing exists until you think about
it. Maybe my mind has been tainted with a sickness to make
me think about bad thoughts and monsters in order to make
them memetically exist. It is the matrix, soipsism, it's the
model that makes most sense computationally.
