minus-squarewanderer@lemmy.worldlinkfedilinkEnglisharrow-up4·6 months ago‘Single celled’ is a characteristic, not a lineage. Organisms don’t necessarily have the same characteristics as their ancestors.
minus-squareaname@lemmy.onelinkfedilinkEnglisharrow-up2arrow-down2·6 months agoYou’re seriously splitting hairs about lineage when you know humans are obviously not fish.
minus-squarewanderer@lemmy.worldlinkfedilinkEnglisharrow-up1·6 months agoA species can not evolve out of a clade. I am not splitting hairs, I am simply accepting cladistics classification as valid.
minus-squareaname@lemmy.onelinkfedilinkEnglisharrow-up1·6 months ago I am simply accepting cladistics classification as valid. Obviously you are not, since fish are not considered a monophyletic group.
