Which is unsurprising as any original self replicating organisms that showed up significantly later would be at a massive disadvantage, and early competition had billions of years to find a winner.
It’s worth remembering that evolution can end get stuck in suboptimal solutions because they still beat 99.999…% of the possibilities. Our blindspot is an issue but it showed up early enough that there’s been vast amounts of optimization based around that initial slightly sub optional feature.
