No consensus has developed on exactly where this find fits into the human family tree (or, more appropriately, “family bush”), but, even if it is a hominin, it is highly unlikely to be a direct ancestor of , then, emphasizes an evolutionary pattern that seems to have been a characteristic of the tribe Hominini from the very start—a pattern that aligns it with what is observed in most other evolutionarily successful groups of mammals.
Human evolution, it appears, has consistently been a process of trial and error.
It is difficult to say how the wide variety of early hominins were interrelated.
Moreover, although these ancient forms were clearly members of the same larger group, discerning exactly how any of them may have been connected to later species is problematic because of incomplete fossil evidence or different interpretations of the same evidence.
Some paleoanthropologists extend the span of this species far back into time to include many anatomically distinctive fossils that others prefer to allocate to several different extinct species.
In contrast, a majority of paleoanthropologists, wishing to bring the study of hominins into line with that of other mammals, prefer to assign to molecular clocks to calculate how long species had been separated from a common ancestor.
These are thought to belong to the same species as the remarkably complete 1.6-million-year-old skeleton named “Turkana Boy,” found at nearby Nariokotome.
This early radiation (diversification) of hominins, of which the latest survivors lived as recently as about 1.5 mya, made for a rather motley assortment.
Historically, this process has been considered a more or less direct series of assumed improvements within a single lineage that eventually culminated in the burnished “perfection” of .
As flattering to the modern human ego as this picture may be, it is evidently quite wrong.
Given these apelike cranial proportions, it is hardly surprising that many paleoanthropologists have characterized these early hominins as “ from Hadar, Ethiopia.
Ardi’s skeleton, which is more than 50 percent complete, dates to about 4.4 mya.
