Subject: How could have the coelacanth been dated back 300 million years ago?

I'm sorry for the misconception of my question to you last time about the 
coelacanth. I was not stating that it was implausible or impossible for the 
coelacanth to be alive after millions of years, but rather how is it possible 
for the coelacanth to be alive today without any striking or drastic evolution 
taken place? Surely if amphibians or sea creatures evolved into mammals or 
land creatures due to weather or simply random DNA, why didn't the coelacanth 
experience evolutiondue to weather circumstances or random DNA change, like 
every other species. Please do not misunderstand my motives, the only reason i 
write to the MadSci Network is because it gives my insight and replenshes my 
thirst for knowledge, and if i were to hold to my views without knowing 
otherwise, how would I ever know if what i am stating is true or not. That is 
why i sincerely appreciate all your responses, for we both gain knowledge 
through our responses, and that is what science and knowledge is all about.
