I don't know what you think this means, but I don't know that anyone is claiming definitively that we know our evolutionary lineage. I don't know that they ever have.2 of 2

human evolution | History, Stages, Timeline, Tree, Chart, & Facts
8.1-Australopithecus afarensis (Lucy), the most famous specimen of Australopithecus is “Lucy,” (the specimen included several hundred fragments of bones collected over three weeks that may or may not be from a single individual) from Ethiopia that has been dated to 3.2 mya.
Here is how Britanica currently identify it “GROUP OF EXTINCT PRIMATES CLOSELY RELATED TO, IF NOT ACTUALLY ANCESTORS OF, MODERN HUMAN BEINGS"
Australopithecus | Characteristics & Facts
- In May 1999, the well-recognized Science et Vie journal used the title "Adieu Lucy" (Goodbye Lucy) on its cover and wrote that the apes of the Australopithecus genus should be removed from human genealogy.
- April 17, 2007, PNAS wrote “This particular morphology appears also in Australopithecus robustus. The presence of the morphology in both the latter and Au. afarensis and its absence in modern humans cast doubt on the role of Au. afarensis as a modern human ancestor."

- Apr 2020, ScienceAdvances wrote” Contrary to previous claims, sulcal imprints reveal an ape-like brain organization and no features derived toward humans.”

**LUCY IS AN EXTINCT PRIMATE THAT IS WITH NO CLEAR EVIDENCE TO JUSTIFY ITS CONSIDERATION AS AN ANCESTOR, YET IT'S STILL USED IN SCIENTIFIC REFERENCES AS A HUMAN FOREBEAR.**
8.2- Homo habilis (Handy Man) lived 2.4 million to 1.4 million years ago in Eastern and Southern Africa
- Apr 1999, Science wrote:
“We present a revised definition, based on verifiable criteria, for Homo and conclude that two species, Homo habilis and Homo rudolfensis, do not belong in the genus.”
“Thus, H. habilis and H. rudolfensis (or Homo habilis sensu lato who do not subscribe to the taxonomic subdivision of “early Homo”) should be removed from Homo."
“Both H. habilis and H. rudolfensis should be transferred to the genus Australopithecus “ see 8.1 above for Australopithecus

- January 2000, MBE published an article stating:
“This may seem to be an unexpected statement, because for 3 decades habiline species have been interpreted as being just such transitional taxa, linking Australopithecus through the habilines to later Homo species. But with a few exceptions, the known habiline specimens are now recognized to be less than 2 Myr old (Feibel, Brown, and McDougall 1989 ) and therefore are too recent to be transitional forms leading to H. sapiens.”

“Who Was Homo habilis—And Was It Really Homo?”
“In the past decade, Homo habilis's status as the first member of our genus has been undermined"

**EVEN SO H. HABILIS CANNOT BE CONSIDERED AS A TRANSITIONAL FORM LEADING TO H. SAPIENS BUT YET HOMO HABILIS IS STILL USED IN SCIENTIFIC REFERENCES AS A HUMAN FOREBEAR. **
8.3- Homo erectus (sometimes called Homo ergaster) lived between about 1.89 million and 110,000 years ago in Africa and Asia.
- 1994, Courier Forschungsinstitut Senckenberg published a research with the title
“The Case for Sinking Homo erectus”
The group of researchers from USA, Australia, Czech Republic & China said:
" There is no distinct boundary between Homo erectus and Homo sapiens in time or space”
“There is no speciation involved in the emergence of Homo sapiens from Homo erectus. These reasons combine to require that the lineage be regarded as a single evolutionary species.”

- October 1997, Nature wrote:
“ Even with the discovery of Neanderthal genetic material, we still cannot decide whether the Neanderthals were one of several related species in an extinct radiation, a single species close to our own, or a ‘race’ of H. sapiens (with that species redefined to include 2 myr old H. erectus).”
One skull does not a species make - Nature.
- June 22, 2015, LiveScience wrote:
“The lineage and evolutionary history of H. erectus and other Homo species is unclear, and has been muddied further by recent finds.”
“Confusing matters more, after analyzing a new skull — called Skull 5 — in 2013, researchers made the controversial argument in the journal Science that various contemporary Homo species, including Homo rudolfensis, Homo habilis and possibly Homo ergaster, were actually Homo erectus.”
“Scientists also don't agree on whether H. erectus is a direct human ancestor to Homo sapiens.”
Homo Erectus: Facts About the 'Upright Man'
**EVEN SO H. SAPIENS WAS REDEFINED TO INCLUDE H. ERECTUS AS A SINGLE EVOLUTIONARY SPECIES BUT YET H. ERECTUS IS STILL USED IN SCIENTIFIC REFERENCES AS A HUMAN FOREBEAR. **
8.4- Homo neanderthalensis (Neanderthal) lived about 400,000 - 40,000 years ago in Europe and southwestern to central Asia.
- April 2014, a study published on PLOS ONE based on 151 earlier papers about the Neanderthal, showed that Neanderthals were not less intelligent than modern human.
“archaeologists’ characterizations of Neandertals as cognitively inferior to modern humans have created an interpretive framework within which subtle biological differences between Neandertals and modern humans tend to be overinterpreted”
“archeological record was not different enough to support the purported cognitive “gap” between them and their contemporary modern humans.”
Neandertal Demise: An Archaeological Analysis of the Modern Human Superiority Complex
- June 2020, a study published on the Royal Society showed that Neanderthal and anatomically modern humans (AMH) were capable of interbreeding to produce fertile offspring.
https://royalsocietypublishing.org/doi/10.1098/rspb.2020.0690#d1e1039
Neanderthals were not less intelligent than modern human; their brains were just as large as ours and often larger. Neanderthals practiced same sophisticated and symbolic behavior like modern humans. Neanderthals were homogeneous species capable of interbreeding with AMH. Neanderthals genome sequence showed same 99.7% genetic material of modern humans, meaning Neanderthals were humans and most importantly they were not human ancestors.
**EVEN SO NEANDERTHALS WERE NEITHER TRANSITIONAL FORMS LEADING TO H. SAPIENS NOR HUMAN ANCESTORS, YET NEANDERTHALS ARE STILL SHOWN OR IMPLIED TO BE AS SUCH IN SCIENTIFIC REFERENCES.**
ALL OF THESE SPECIMENS WERE EITHER PRIMATES LIKE THE CASE OF “AUSTRALOPITHECUS AFARENSIS” OR ACTUAL HUMAN LIKE “HOMO NEANDERTHALENSIS”. THERE IS NO EVOLUTIONARY TREE, NO TRANSITIONAL SPECIES, AND NO COMMON ANCESTOR OTHER THAN IMAGINATION AND WISHFUL THINKING. GREAT MINDS AND GREAT EFFORTS ARE WASTED, EVEN SO REAL WORLD DATA NEVER SUPPORTED THE PREDICTIONS OF THE TOE BUT UNDER THE FALSE NOTION THAT ONLY ONE (UNFALSIFIABLE) HYPOTHESIS IS POSSIBLE, THEN ALL OBSERVATIONS HAD TO BE INTERPRETED TO FIT THIS HYPOTHESIS.
Why do you have to pump so much into posts and why all the bolded caps? Are you angry?
