An interesting evolution study

paraphrase: “loss of a complex trait is often irreversible”
“genetic coding data indicates complex trait studied did not arise multiple times, contrary to conclusion which would be reached based on statistical analysis of living species with said trait” (that sounds a lot like complex traits must be inherited from ancestors to me… 
)
quote: “The study contradicts earlier studies of complex trait evolution, which have tended to favor multiple reappearances of complex traits after these organs were lost in ancestral species.”
