Santiago Claramunt @sclaramunt.bsky.social · 29/09/2026I agree, hominoids are a basal clade. But they are not “ a lineage” I the strict sense (a single line of ancestors and descendants) 000
Santiago Claramunt @sclaramunt.bsky.social · 29/09/2026That basal node is the origin of the clade. That is what makes a clade “basal”. It is jargon, and I see how it may be confusing for some, but it is a very useful word for describing phylogenetic relationships verbally. 110
Santiago Claramunt @sclaramunt.bsky.social · 29/09/2026Not exactly, Paleognathae is indeed a basal clade, in the sense that it originated at the base of the avian tree (crown clade) 200
Santiago Claramunt @sclaramunt.bsky.social · 29/09/2026No, because hominins are multiple lineages. 100
