First off, im sure those hox genes dont control tightness of legs, size of heart and everthign else ive mentioned let alone the co ordination of there growth. Did you see any co ordination with those fruti flies..nope, we had heads coming out of eyes, and of course the legs had no blood supply, which means that the veins must be controlled by a differetn gene. either way, invoking hox genes simply means nothing becuase, there amount of growht would still have to be proportional, and judging by teh fruitly mutatons that is a serious long shot...of course ive yet too see girrafes fossils that look like anything drastic happened in there hox genes..(maybe we just havent found them yet?) this is very different since its not coevolution its co growth from a pre existing recipe. the coevolution involves long stretches of time where diffrent parts of the anatomy gain complementary mutations..which, for me at the moment, hard to swallow, but maybe im wrong, Ill just have to keep studying. well im glad that you are the first person to admit that indeed you do belive that these things had to keep up..everyone else just danced around it. Of course you have just admitted to invoking a miracle. Do you realise how many changes your talking about, over 6 mllino years, with only an average of 60 mutations per germline and most are in non coding regions do you know the task you are setting the mechanism?(that stat was for humans, but im sure it cant be much less or more for girrafes, of course im open to be proven wrong) How many times do you think the same mutations occured? since you obviosly think there were alot of failurs then teh same thing must have occured over and over... Its not as simple as simply claiming those others died, indeed how do you you test that many of those mutations happened and produced failed attempts? what would be the evidence for that. Since not all of the needed chagnes would be linked to the same hox gene then you are invoking a miracle(either way).. I see no strong evidence at all for this claim, and it gets worse a thousand fold when we talk about symbiosis or sexes etc, the problem gets so bad as to become biblical! I will adress this in a future thread should you wish to check it out.. not to mention you obviously feel this is a common phenomenon. Did you see those italian wall lizards i posted on? One can only invoke faith when applying the mechanisms to that incident.
