Ontogeny recapitulates phylogeny: Baby baleen whales have teeth (before they lose them)

As a final note on my series on whales, I’ll mention an interesting tidbit about teeth. Despite the fact that baleen whales lack teeth entirely, fetal baleen whales do have tooth buds that never fully develop.

This ties in nicely with both the fossil and genetic evidence that baleen whales descended from species that lost their teeth as they transitioned to filter feeding.

Questions for creationists

Why would God create baleen whales with tooth buds that fail to fully develop? Is it a coincidence that whales have tooth pseudogenes and putative transitional fossils showing evidence of losing teeth?
