Funny you should mention that - because that is exactly what we see at the cellular level.
No. Try reading through what Percy wrote again. (Or, possibly, for the very first time.)
On the cellular level, we do not see:
(a) Massive complexes of laboratories to design organisms on a world-wide scale about 6000 years ago.
(b) Significant infrastructure for world travel about 6000 years ago.
(c) A major genetic bottleneck affecting all species about 6000 years ago.

You mean, other than the irreducible complexity I eluded to above? Nope that's it.
(1) You were asked for positive evidence of design, not just an argument of the form "evolution couldn't do that, therefore it was designed". But this false dichotomy is exactly what creationists' blunders over irreducible complexity amount to.
(2) You said in your OP:
While mutation often results in a lethal phenotype knockout experiments on SRC genes show that mice can survive without some SRC genes.
Hence, the system is not irreducibly complex.
(3) If it was, then since we know that IC can evolve, it would not constitute evidence against evolution, let alone evidence for design.
