Wow, nirwad is dumb.
He concludes humans and chimps are less similar by using a 30 nucleotide search of the genomes that relies on identity to score a 'match.'
Doesn't he know going to longer strings, without offsetting by allowing mismatches simply amplifies the likelihood of not getting perfect match, so the number of matches decrease!
For example: consider a 59bp genome A, with a single mismatch in the middle relative to B. 58/59 is 98% identity. Now query with a 30 nucleotide search. No alignment will have 100% identity. So nirwads 'search' can take 98% and make it 0%. Well done.
I'm sure there is a way to demonstrate algorithmically that a 30nt search string, that requires identity to match a 99% similar target will give precisely the results he gets (which are in the 60% range).
Of course the hallelujah chorus locks onto this as proof we aren't related to chimps. Here's a suggestion: go to really long threads, and you can get it to go to zero!!!! We're totally unique! Evolution is dead!
