Hi

ToE predicts "gradual" progressive evolution from simple to complex.
---------------------------------------------------------------------
ToE doesn't predict progression from simple to complex
It only concludes that the things we observe ( the fossils / the
actual biodiversity etc ... ) are the actual SURVIVORS ---> those who posses ( at this moment ) the ( potential )possibilities to produce progenitures which will be (eventually ) fertile ( succesfull ) in the future
Furthermore
You can only conclude that a phenotype is "in balance with his actual environment "( ---> it works--> it is a set-up of components that performs etc ... ) or that it has reached a "goal "( it's alive now ) when the PROCES ( which always takes time ) to reach the present state , has reached the now ( at least in your observing mind ) ...
... IOW the adjectives "progressive" and "degressive " are only evaluations of OUTPUTS of "processings" ---> not the reverse
progressive/ regressive is only a characteristic derived from the
reached conclusion ...
For Sure there is a ( one direction ) arrow of time ---> it is flowing from past to the future : and it comes together in the now , which is already gone when we try to catch it
Fossils are just some ( preserved ) snapshots
Present biodiversity just an horizontal "slice "of the phylogenetic tree
Gradualism is the film ---> just all the small ( very slowly changing )series of photos
---> if you compare the first and the last " still " pictures of a movie (taking for example 2 hours to project ) they are not at all " slightly "different .... They are VERY DIFFERENT ....
You just missed the in-betweens --> it doesn't mean they weren't
there
Same goes in " recordings " of repetitive minimal music
Some of these performers just "repeat the same thing "( a sequence
--> generally a two bars figure ) in a loop ---> many people find
this boring ---> however if you " record " such a performance and
you only listen to the beginning and the end of the piece ---> you will remark that it is not at all the "same thing " you end up with two completely different sequences ( even the number of bars can
change )
Not finding all the " intermediate steps "( or simply the impossibility to scan them all --> there are really too many of them ) doesn't mean that they don't exist ---> There can be a "butterfly effect "
Sure from simple to complex can also be "defined "( that is approached from another "perspective " ) as
--> progression in the organisation on more higher levels
kind of some "fractional " manner ( see fractionals / Mandelbrot ... etc --> any search engine will do )
?--->Molecular --> protocellular ---> uniCellular --> multicellular ---> social insect states ----> ?
-->Starting from "simple thing " to " complex thing " ?(progression )
--> Starting from " complex thing " to simple thing (regression )
--> or all kinds of combinations of both ? ( Backtracking for example )
Seems ALL to be plausible propositions , from a theoretical point of view
( I personnally like to think that there ARE backtracking strategies in evolution --> of course it is a proposition based on analogies with certain methodologies in problem solving , and I have no biological or genetical evidences to back it up ( this is no CLAIM only a suggestion )
BUT WE MUST NEVER FORGET that we only have " real " acces to the (preserved ) outputs that are still around and some snapshots ...

"ToE doesn't predict progression from simple to complex. "
It isn't about " predictions "
it isn't even strictly about ToE
It's all about terminologies
and about the multiple meaning of words , used in public and general
speech ....
Saying that ToE is "predicting" progression from simple to complex
( that there is a direction ) or for that matter ;from complex to simple /or a combination --->
is a vague statement as long as you are not describing what you mean by complexity or by simplicity
As far as I understand it some "Living creatures "are more complex
in their organisation of components than other simplier ones "
However each of the singular components are very complex
structures themselves
AND the( ecological )interactions of the "living creatures " in the whole biosphere is very complex too
What kind of complexity you are talking about
---> complexity increase in the species ? complexitie increase in the genotypes complexity increase in the phenotypes ? complexity in the design complexity in the planning ? Increase /decrease of information
ON WHAT LEVEL OF ORGANISATION IS A STRUCTURE MORE OR LESS COMPLEX
ToE;
I don't know what toe is saying /predicting
Talk about that with the experts ....
Creationist however --->ToE is saying ( even predicts )
----> etc
But ToE certaintly doesn't say
that the cell is "simplier "then the human being
nor does it predict that the living things ( you call them creatures
I call them survivors ---> or the actual products of ongoing
causal chains ---> well it's all chemistry and nanothechnologies , anyway )
in the future will be complexer or better or worser
Worser or better ?
or complex or simple ?
or good or bad ?
must all be there ---> otherwise it is impossible to say there is a
plan or a directed design or
whatever intelligently plotted scenarios
Simply that there is a movement( be it progressive or regressive or
a combination of both ) and ToE tries to find the mechanism behind
it
all without ,invoking supernatural imperatives ....
I do not make"brilliant observations "
(by the way I don't mind sarcasm , I even appreciate it )
but
I just read in your posts
words , words , words and again words .... "
I think you are brilliant
--> you should try novel-writing and poetry .... ( or maybe you
do it already ... all the time , Bravo )
Sure
'the living creatures are alive'.by definition
is that a problem ?
Something is a survivor because it is the last step in a chain
of descendance and , sure it is alive and well now ...So we can
label it alive ( or maybe it is a virus that is
both alife and death ---> but nevertheless a survivor ---> or
maybe some "created "parasite kind ( maybe by a devil? )
with no ancestry ? )
