>>14068474>or maybe those upright walking organisms that didn't have arched aorta died outLOL no. The entire species and all alleged relatives to primates would have had an arched aorta long "before they walked upright" and we know this because nobody is stupid enough to claim organs can just redesign themselves in a few million or so years.
Feel free to prove me wrong and show me fossil evidence that non arched aorta mammals that almost walked upright died out. Ooops you can't because the fossil record supporting evolution is a faith based religious dream for delusional morons.

>>only those with a better diet survive>It has its ups and downsWhat does this even mean in your head?There is no synergistic effect between diet and tailbones so your statement is meaningless. A better diet helps prevent rectal prolapse no matter if you have a tailbone or not, and it's helpful for other unrelated reasons as well. Humans don't always have access to "better diets" either so the best design choice remains having a tailbone because forcing a species to be more selective with its diet is BAD for reproductive fitness, not good. You obviously don't understand how the hypothesis of macro evolution works.
