mtDNA / Nuclear DNANo / No
Divergence Date (fossil calibrated)5.9 MYA

Orrorin: no genome; hominin total-group context only.

Ardipithecus kadabba

mtDNA / Nuclear DNANo / No
Divergence Date (fossil calibrated)5.5 MYA

Ar. kadabba: no DNA; divergence vs chimps per TimeTree-style priors not directly measured.

Ardipithecus ramidus "Ardi"

mtDNA / Nuclear DNANo / No
Divergence Date (fossil calibrated)4.4 MYA

Ar. ramidus: no DNA; node age approximates last common ancestor of Ardipithecus-grade hominins.

Australopithecus anamensis

mtDNA / Nuclear DNANo / No
Divergence Date (fossil calibrated)4.0 MYA

Au. anamensis: no DNA; used in comparative population genomics as fossil anchor.
