| Apr 19, 2023 at 0:34 | comment | added | Michael MacAskill | @BryanKrause Yes, and there many examples of extant bilaterally symmetric animals with > 2 eyes, eg many spiders have 8. Eyes have evolved independently something like 22 times, so there is vast variety that eludes simple generalizations. | |
