Just for the record, the 98% number keeps changing.
Just for the record, that number depends on how the similarity is measured. Various methods exist.
Some will show 96% others will show 98%, etc.
However, it's always consistent accross the board. No method shows more similarity with mice then it does to other primates for example.
Secondly, a common creator would re-use some of the genome for similiar creations.
That would be a decend argument, if the similarity being talked about would only refer to "common blocks". But that's not accurate. What is striking is the patterns of similarities. Its hierarchical nature. That is NOT something we would expect in context of a "common creator".
Evolution explains why chickens, who don't have teeth, have DNA to build teeth.
Evolution explains why we share an enormous amount of ERV's with chimps (=which is
inserted DNA as a result of an infection).
A "common creation" does NOT explain such a thing. Not at all. In fact, it only raises even more questions.
Just to illustrate....
Imagine a computer that only requires 4 wires to connect all the parts to the motherboard. Analogous to chicken DNA to build teeth, the case of the computer would hold those 4 wires and
in addition another bunch of wires that
aren't connected to anything. Or that are connected to stuff that isn't working, for example a hard drive that isn't connected to the power supply and thus "just sits there".
That's not how an engineer does things.
It's not energy/resource efficient. It's bad practice. It's bad design.
Any engineer working like that would be fired instantly for being a total amateur.
However, a process like evolution would
inevitably lead to such structures.
For evolution, it would actually be a
bigger challenge to explain why a teeth-less animal like chickens would have NO TRACE of genes to build teeth at all!
In an evolutionary context, it is fully expected to find such inactive genes or traces thereof in teethless animals, considering their ancestry.
Another great example is the non-functioning eyes of moles. They can't even open their eyes. Their eyeballs are covered by a layer of skin. Their eyes do not function. But they are still there, hidden behind skin.
An engineer who's going to design a life form that does not have the ability of sight, is not going to give it eyeballs and have it spend resources and energy on developping those eyeballs....
Likewise, an engineer who's going to design a life form that has no teeth, is not going to give it the "codes" to build teeth.
It amazes me that people use this argument..... "similarity = common design". As if a chicken having non-functioning DNA to build teeth or a mole having non-functioning eyeballs is better explained by an "all-knowing perfect engineer" then through the process of evolution - in which it is actually EXPECTED to encounter such structures.
Amazing.
