Hey guys,

Thanks for the interesting discussions, much better than the usual name calling and personal attacks these climate discussions usually draw.

However I do have a problem with the statement;

"During most of the history of life, species have become extinct at a slow, fairly regular pace."

As a scientist with an interest in evolution (mostly at the bacterial and viral level) this is complete crap. However, I usually pay attention to articles published in a prestigious journal such as 'Nature' so may have to check out this article.

I'd also like to thank 'under one god' for his recognizable (terrible) use of quotation marks is his comments. This allows me to immediately skip reading what usually turns out to be an incomprehensible ramble.

ha ha//stezza has never gone past page 4..of any evolution debate
having lost them all...lol

http://forum.onlineopinion.com.au/search.asp?cx=partner-pub-0168091956504304%3Ayb7rk7-ta83&cof=FORID%3A11&ie=windows-1252&q=stezza+evolution&sa=Search#992

not that he is alone
none have been able to present the evidence
a few admit..evolution is a theory...but stezza dont stick with debate for long..so few facts...so many fixed opinions

sadly i read all of everyones posts...im not afraid of what they might have to learn...but its not for everyone

funny how the same teqniques get repeated..

note a blanket statement...,,<<..As a scientist>>..lol..with an interest in evolution..(mostly at the bacterial and viral level)..this is complete crap....>>>ok strong statement..BUT THEN...NO EVIDENCE...

further he takes it out of context...to big-note his presumed..authority...lol...

FULL/quote<<..The rate at which species are becoming extinct is also far beyond a safe boundary,..according to the scientists.>>>not the auther

further<<..During..most of..the history of life,..species have become extinct at a slow,..fairly regular pace.>>>here the aurther obviously refers to the theory...of gradual evolution...lol his theory...lol

<<And as old species have become extinct,..new ones have been evolving.>>>get it brother?

<<There have been times...when many species have become extinct at a much faster rate,>>>obviously in referance to the dino extinctions...not that the person noted..the full context...lol

but such is the way..of those
who wish to make statements...in lue of fact...lol

put up some proof...but you cant..
you got none
as is well reflected..by your previous postings..then running away

ie your few sharp words are only opinion...lol

Yea, sorry 'under one god' my comment was a bit harsh.

You are right however, I could not convince you of the theory of evolution in our previous debates. Also, I probably could not undeniably prove to you that the world is round, or that it is older than 6000 years old. Luckily thats not my problem.

I will not attempt to convince you of any of these things, as I believe it is impossible to convince you otherwise. I however am able to adapt my beliefs in light of new evidence. Are you able to present an alternative theory to evolution and have it withstand scrutiny?

Lets see.
