A) All hominins (~6 Ma)
B) Genus Homo (~2 Ma)
C) Homo sapiens (~300 ka or ~200 ka)
D) Post-140,000y hominins (incl. REAL (post-140 ka) Neanderthals & Denisovans, Eyasi 1-like Africans except the latest Erectus from Java)

It is not possible to know when a hominid is already a human being. Only the cranial capacity of well-fossilised fossils can give us some guidance. Although it is not entirely certain, for the moment, only those with more than 1,200 m3 of brain matter could be the transitional beings, a kind of "RUbicon". This measure is not reliable either, since in our own species, there are individuals containing about 1,000 cm3 and 2,000 cm3, and both have the same capacities (Anatol France and Cuvier). The cranial fossils do not show the neuronal connections and their density, so little or nothing can be said.
Another parameter is the hand tools, the tools that indicate the progress of the brain.

"It is not possible to know when a hominid is already a human being."
Dependent on the testing NEW PARADIGM.
The oldest-known brains of Sapiens are 1500+cc (cm3), see the attached figure. A sudden increase due to the macroevolution?
Homo sapiens sapiens: 1350-1400 cm3 aprox.
Homo sapiens neanderthalensis or Homo neandethalensis: 1500- 1600 cm3
If LB1 was a retrogressive form of Sapiens (with ~400 cc brain), Sapiens' brain volume is extremely flexible.
In this case, a new species concept to biology:
PARADIGMATIC SPECIES CONCEPT?
Human is a mass of flesh, bones, and ''feelings'', ''Spirit'' Human beings are the most recent representative of the family Hominidae. Humans are mammals that usually live in a group to protect each other. Humans have complex brain and walk on two legs, as well as have vision, sight, and hearing...etc.
