Teaching Evolution

Things that replicate are at the heart of the evolutionary
process. Genes replicate with high fidelity and only very
occasionally have random inheritable errors (mutations).
They pass the error onto the offspring. Vast majority of
time the error will make the replicator/offspring less fit
(fit = good at replicating basically, ie. making lots of
copies, making copies fast, making copies with few errors)
giving it a lower probability of surviving relative to
competing alleles. But some random asshole that does
something retarded like code for protein or whatever the
fuck that puts some extra shit on some d00d's skull and over
time its like, omg 'antlers'. And now this crazy asshole is
walking around with rediculous looking spikes all over his
head i mean come on... 111 !
But planets have no underlying replicator, no not atoms or
something because they're not replicators. Fire is not a
replicator, humans aren't replicators even though they have
kids (because by definition a replicator makes a copy and
the child isn't anywhere near an exact copy).
Evolution is a mass search algorithm. you can think of all
like as the same dna strand finding what is most fit in
parallel with all forms of life even taking into account
other forms of simultaneously evolving life as part of its
environmnent. ef0foiaeroijhreioj
you can't take all the disassembled junk yard scraps of an
airplane and have a tornado randomly assemble it into an
airplane all in one go. Evolution is gradual where each
intermediate stage was 'fit' at the time. Half an eye was
fit but it wasn't 'half an eye', just a half evolved
eye, perhaps starting as light sensative skin.
Artificial evolution works, I don't really get the
confusion, just read dawkins 'selfish gene'. He's popular
for 'atheism' now but that previous book really nails
everything. He basically answered 'what's the meaning of
life' and has tons of profound insights such as how the
beginning replicating ancestors of dna might have started.

The real question is, why does something exist instead of
nothing. But thats a more philosophical one. If religion and
science collide than on the philosophical basis (naturalism,
materialism) and not the actual facts of evolution.

I recommand Bunge/Mahner over Dawkins. Dawkins is an Idiot
(well at least when he speaks bout religion)

i don't have a problem with the concept of evolution, just
the classic darwinian model.

- the concept is mostly the same- darwin didn't know about
gregor mendel mechanisms, and now the gene is regarded as
the unit of selection instead of the individual/group.

the fossilrecord does not show the proportionate amount of
mistakes
that would be necessary for new species to be generated by
random process

- genes of species that went extinct are the unfit
'mistakes' of evolution's mass search algorithm in the
fossil record, (unless a random process like an asteroid
collision removed them). If a mistake had no momentum then
it didn't replicate enough to result in fossils. Maybe the
genes have the potential to produce hideous
monstrosities of one sort or another, doesn't mean anything
was selected to evolve along that path. Still some genes of
dinosaurs etc replicate on (like whatever genes result in
having a head, etc). The genes are the replicators while
individuals are temporary 'vehicles' (it was apparently more
fit for individual genes to bunch up into multicellular
organisms).

evolution seems more like the stages of life,
seed to a tree, caterpillar to butterfly and so on.

-That's like life cycle/embryonic development stuff,
something genes code for, not really about the selection of
fit genes.

i don't think saying there is evidence of an order and a
system has to open the god can of worms.

-well the scientific estimate of the earth age supported
with evidence etc contradicts equivalent 'truths' of widely
replicated religions. Or if you want to be less
religion-specific and just say maybe there's a being that
created the universe/world, be it a giant throbbing amoeba
or whatever, you havn't solved what created that creator and
are back at square 1. Some things are designed by a creator,
like an airplane. But those creators underwent evolution by
natural selection.

of course it is, what are you talking about?
science is not dogmatic and never gives definite answers
which is why it's science and it's good

those "monsters" could not adapt as good as others. This, I
think this is reson why fosils of "monsters" is not found,
thats becouse they was rare.

"what i do have a problem with is the idea of random
mutations complex enough to actually result in speciation,
planet formation, stars, sentient organisms with
consciousness, etc. like the article gets into, the fossil
record does not show the proportionate amount of mistakes
that would be necessary for new species to be generated by
random process, if thought about logically and you do the
math.
"

You cannot “do the math.” It is random (or arbitrary
anyway), so it is entirely conceivable that the entire
process happened without so much as a single “mistake.”
In addition, as IAN NOLL said, the “mistakes” are
the fossil record.

What's the problem with Dawkins? Genuinely curious here. I
like him.
