Range unicellular eukaryotes <10^8, sometimes 10^6: invertebrates ~10^6: some vertebrates 10^4 individuals

Comments P.3 left column 3rd paragraph:"Unicellular eukaryotes often have Ne<10^8, sometimes ranging down to 10^6 , implying that insertions of small to moderate size will frequently be unmovable by natural selection...The effective population sizes of invertebrates tend to be in the neighborhood of 10^6, with that of some vertebrates (including humans) ranging down to 10^4, and in such cases the power of random genetic drift is sufficient to overwhelm the ability of natural selection to eliminate quite large insertions on the basis of DNA-level costs."
