If a trait $\mathrm{A}$ exists in $10 \%$ of a population of an asexually reproducing species and a trait $\mathrm{B}$ exists in $60 \%$ of the same population, which trait is likely to have arisen earlier?
If a trait $\mathrm{A}$ exists in $10 \%$ of a population of an asexually reproducing species and a trait $\mathrm{B}$ exists in $60 \%$ of the same population, which trait is likely to have arisen earlier?
