We can also live just fine without an appendix. Literally the only thing the organ can do is suddenly develop a severe infection and kill you without surgery which has only become reliably available in the past 100 years or so. (Blah blah bacterial reservoir or whatever: that's of evidently very low value compared to sudden and painful death)

There's also no reason we shouldn't be immune to funnel web poison: cats make an enzyme which deactivates it, whereas primates don't.

There is also no reason our eyes can’t see in the dark because cats can and no reason to not to lay eggs because that’s more practical and way less dangerous (and probably painful) than giving birth directly. Also too bad that we haven’t multiple hearts for redundancy.

Ok.

So what does that means ?

Means there's room for improvement.
