The article doesn’t seem to mention it, but I’d be curious to know if this or similar duplication contributes to how many organisms - including humans - display symmetry and use it as a sign of genetic fitness.
Eg. Humans. Lots kv studies show people finding symmetrical faces attractive.
Maybe symmetry is the body’s way of showing off how good it is at producing the same outcome twice - and attraction comes from the idea that that body could do it for your offspring too.
