The critical phrase being "if Kurt is correct." If 5-6% is
enough to separate baramins, then what do you say to the
following matrix?

P_trog G_gori

H_sapi 0.67% 0.67%

G_gori 1.32%

These percent differences were computed from an alignment of
human (H_sapi), chimp (P_trog), and gorilla (G_gori) myoglobin
sequences. We would have to say that a mere 0.67% protein
sequence difference is enough to separate baramins. This would
mean that your turtle samples are not in the same baramin. My
point is this: sequence information is not widely applicable.
Different baramins have speciated differently. Some have
literally exploded (the insects) while others have produced
only a few species (human, platypus, and aardvark). We have to
use the sequence information in conjunction with other
characteristics. I stand by my claim that sequence information
alone is insufficient to determine baraminological
relationships.

I do want you to know that I appreciate the work you are
doing. We definitely need more creationist molecular
biologists.
