In this paper, the morphology of chicken mutants with the autosomal recessive mutation taplid2 is described. Rather unusually, bearers of this mutation develop teeth and a jaw structure bearing significantly more in common with crocodiles then with other chicken, and the mutation occurs on the same homologous region used for development of reptile mouths. From an evolutionary perspective, birds - now a seperate clade of reptiles - no longer express teeth, but have not necessarily lost the genes with which to make them. If, as YEC science contends, genetic homologies are evidence of essential common design -theres no such think as junk, organismal dna shows no evidence of common descent- why did god feel the compulsion to include such bizzare characters? What purpose does it serve? Is it a co-incidence, and nothing more?
