[ELI5] What’s the difference between a clade and a taxon?

And can one species with no subspecies (like the very lowest branch of the phylogenetic tree with no subbranches) be a clade or a taxon?

Answer 1

A taxon is much more general, and refers to any group that taxonomists place organisms into. A clade is that, plus the organisms share a common ancestor. A clade is a type of taxon, specifically a monophyletic taxon.
