Purported examples of poor design usually represent opinions resulting from armchair critics’ limited understanding of the technical literature.
Organizers of the St. Louis World’s Fair believed human zoos would “shed light on the theory evolved by Darwin as regards the evolution of the human race.”
Darwinian evolution will never succeed in disentangling itself from racism because it must always have its “official subhuman.”
You can watch Axe taking on arguments for “stupid design,” as offered by well known atheists like Neil deGrasse Tyson or lesser lights such as Nathan Lents.
A couple of years ago, Professor Lents became fascinated by orphan genes, and went looking for them in the human genome.
