TAT tHERE'S A POINT i'VE BEEN TRYING TO MAKE THAT i DON'T THINK i DO A VERY GOOD JOB ON. THIS TIME i WANT TO TRY AGAIN USING THE THEORIZED EVOLUTION FROM A LAND ANIMAL TO WHALE, SOMETING LIKE A RHINOCEROS TO WHALE.
wITHIN A SPECIES VARIATION FOLLOWS SET PATTERN, IT'S BUILT IN TO THE GENOME, ONE OF TWO ALLELES FOR A GIVEN GENE COMBINE WITH ONE OF TWO FROMT HE OTHER PARENT TO PRODUCE A PTRAIT IN THE OFFSSPRING, A VERSION OF A TRAIT THAT MAY BE THE SAME OR DIFFER SOMEWHAT FROM THAT OF THE PARENTS.
bUT EVOLUTION FROM ONE SPECIES TO ANOTHER HAS NO SET PATTERN IT PRETTY MUCH HAS TO MAKE A NEW GENOME SINCE THE ONE IT STARTS FROM HAS NOTHING BUT GENES FOR THAT PARTICULAR SPECIES. tHESE CHANGE FROM GENERATION TO GENERATION ACCOREDING TO THE PATTERN i MENTION, AND IF THERE'S A MUTATION THAT GETS TREATED LIKE AN ALLELE SO THAT IF IT PRODUCES SOMETHING AT ALL USEFUL IT WILL BE PRESERVED BUT MOST OFTEN IT DOESN'T AFFECT THE OUTCOME AT ALL OR IT MAY PRODUCE A GENETIC DISEASE. iF TIIT SHOULD BE USEFUL THOUGH IT WILL JUST DETERMINE THE TRAIT AS ANY OTHER ALLELE WOULD, THAT PARTICULAR TRAIT THOUGH PERHAPS IN A NEW VERSION. bECAUS THAT IS WHAT THAT GENE does AND YOU CAN'T GET AROUND THAT AS FAR AS i CAN SEE. iF i'M WRONG THEN i HOPE TO FIND IT OUT SOON.
bUT OUTSIDE THE GENOME AS IT WERE, IT'S ALL RANDOM, IT'S ALL CHANCE AND IT'S ALL MUTATIONS. tHAT BEING THE CASE HOW DO YOU GET AROUND THE FACT THAT MUTATIONS ARE JUST GOING TO PRODUCE IRRELEVANT CHANGE AFTER IRRELEVANT CHANGE, CHANGES THAT DO NOTHIJG USEFUL OFR THE ORGANISM AT ALL LET ALONE LINE UP WITH OTHER UCH CHANGES TOWARD A FULLY EVOLVED END PRODUCT LIKE A WHALE FROM A RHINOCEROS. a CHANGE IN A GENE WOULD ONLYU FFECT ONE TRAIT, YOU'D NEED COMPATIBLE CHANGES IN ALL THE GENES FOR THAT TRAIT WHEN THERE ARE MANY THAT CODE FOR IT WHICH IS OFTEN THE CASE, HOW ARE YOU GEOING TO GET COMPATIBLE MUTATIONS EVEN IF YOU BAZILLIONS OF YEARS FOR IT TO HAPPEN?
eVLTIONISTS AS FAR AS i'VE SEEN DON'T EVER DISCUSS THE HOW OF ALL THIS. tHEY SAY GENERAL THINGS LIKE SINCE EVOLUTIONIS TRUE ACCORDING TO THEM THEREFORE SOMETHING LIKE A RHINOCEROS SIMPLY EVOLVED INTO THE WHALE, AND IF THAT SEEMS UNLIKELY WELL YOU JUST HAVE TO LEARN TO THINK IN HUGE SPANS OF TIME, MILLIONS OF YEARS. bUT MILLIONS OF YEARS DON'T DO ANYTHING BUT AVOID THE QUESTION, WHICH IS WHAT MECHANISMS HAE TO OCCUR FOR THE EVOLUTION TO HAPPEN? aND THAT'S WHAT i DON'T SEE THE SCIENTISTS ATTEMPTING TO DEAL WITH. oH NATURAL SELECTION DOE ALL THE WORK. wELL, BUT TELL US how YOU THINK IT WORKS, WHAT DOES IT HAVE TO SELECT FROM? aNDWOULDN'T IT HAVE TO HAVE THOUSANDS UPON THOUSANDS OF CHANGES IN THE ORGANISM TO SSELECT ASSUMING THEY WERE ALL USEFUL AND THEREFORE SELECTABLE. bUT AGAIN WHAT MAKES IT AT ALL LIKELY THAT any WOULD BE USEFUL AND THEREFORE SELECTABLE IF WE'RE TALKINGA BOUT RANDOM MUTATIONS.
tO MY MIND THIS IS JUST ANOTHER WAY THAT EVOLUTION IS IMPOSSIBLE. aND AS LONG AS THE SCIENTISTS TALK ONLY IN GENERALITIES AND DON'T TRY TO ADRESS THE SPECIFICS OF HOW IT COULD WORK IT'S ALL A MAGIC TRICK OR SMOKE AND MIRRORS, JUST A \N EMPTY SHELL OF N IDEA.
i DN'T KNOW IF i'M BEING ANY CLEARER THIS TIME AROUND OR NOT, MAYBE SOMEONE ELSE CAN IMAGINE THIS OUT BETTER THAN i CAN, BUT NO MATTER HOW i THINK ABOUT IT ALL i GET IS ENDLESS MISTAKES IN MUTATION THAT GO NOWHERE THAT COULDN'T GO ANYWHERE EVEN IF YOU GIVE THEM A TRILLION YEARS TO DO THE JOB.
nO, i'M NOT SAING IT VERY WELL. gOOD GRIEF. yOU NEED A WHOLE NEW GEOME, TAHT'S TH PROBLEM BUT THE ORIGINAL GENOME CALLS THE SHOTS AS IT WERE. TO GE A NEW GENOME YOU'D HAVE TO DESTROY THE ORIGINAL ONE, i SUPPOSE GENE BY GENE. bUT ALL TAHT DOES IS PRODUCE JUNK dna.
yOU CAN'T GET THERE FROM HERE, THT'S JUST A FACT. THERE IS NO PATH TO WHALE FROM LAND ANIMAL, OR FROM DINOSAUR TO BIRD. iT CAN'T HAPPNE. aND THE FACT THAT SCIENTISTS DON'T EVEN TRY TO SKETCH OUT A PATH IS HIGHLY SUGGESTIVE OF THE POSSIBLITIY THAT THEY KNOW THER IS NO WAY TO GET THERE SO THEY LEAVE IT ALL IN GENERAL TERMS. tIME AKES IT POSSIBE. nATURAL SELECTION DOES IT ALL. ETC.
