Subject: What are the different bandwidth of DNA in different species: humans etc.

"It's funny how people always try and use dogs for their examples, yet
they always seem to leave out the fact that dogs have the widest known
bandwidth in their DNA that allows genetic diversity, this isn't the
norm. You're scenario is impossible if applied to a cheetah which have
a very narrow bandwidth. This narrow bandwidth even prevents
micro-evolution for all practical purposes. Beneficial mutations don't
happen. To pretend they do helps the theory…but it's not good
science".

It is from the http://www.politicalcrossfire.com/forum/viewtopic.php?

I am not really a scientists to know what other word to use instead of
bandwidth but I hope the full quote is helpful.

Thank you in advance for your help.

PS: I would like to have some elaboration on the point of DNA's
bandwidth - as he calls that. Of course, the above quote does not
necessarily reflects my standpoint.
