If similar genes do not mean similar function, then common descent truly is meaningless. Especially in light of your 'convergent evolution' claim.

If 'convergent evolution' is true, then 'evolution' can produce similar genes without 'common descent' and 'common descent' has been falsified.

If similar genes do not mean similar function, then common descent truly is meaningless.

Genes can duplicate and then diverge in function. These are called paralogs. Bioinformaticists trace their common descent by the pattern of sequence divergence. Many proteins are sequentially homologous without being functionally similar.

If 'convergent evolution' is true, then 'evolution' can produce similar genes without 'common descent' and 'common descent' has been falsified.

You are confusing sequence convergence with functional convergence. Evolution predicts the latter will occur without the former. Evolution's prediction is borne out by bioinformatic analysis.

No. Convergent evolution refers to convergence of function, not convergence of genes. You really are bluffing this stuff, aren't you.
