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

Question

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 clade is a group of organisms that share a common ancestor and all its descendants. A taxon is a group of organisms that are classified together based on some criteria. Not all taxa are clades, but all clades are taxa.
