Re: why Cytochrome C... why neutral...
Hi judge,
This statement in the paragraph you quoted rang alarm bells for me :
quote:
It could be called extraordinarily coincidental, if not to say miraculous, that these neutral changes always and only take place around the diverging of two species.
The author seems to have based it on information that probably doesn't exist. How do they know that cytochrome C doesn't vary within the same species of shark? What study is this based on? How much individual sequence data is there on the shark genome?
Cytochrome C seems to vary in humans for example. I've just queried "cytochrome C NOT oxidase" here and I found that items 7-49 had variations in the cytochrome C gene (the first 6 were from another gene with cytochrome C in it's name). That's quite a lot of variation for genetic drift to play with.
I would add that I am not a geneticist so I may have committed a horrendous error here (people are welcome to correct me and make me look daft ), but I'd still want to see the studies that show that no variation is seen within species.
Cheers

Re: why Cytochrome C... why neutral...
Yeah...
well...
that is of course another way of doing it. If you wanted to make it easier to do and much more easy to understand.
Cheers Wounded.
Sometimes I wonder why I bother
