These fossils, along with the slightly older trails of footprints found at Laetoli, Tanzania, prove that early hominins were upright bipeds when on the ground.

However, they also retained many reminders of their tree-dwelling ancestry, especially their rather long arms, short legs, narrow shoulders, and long grasping extremities.

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.

Instead, human evolution has been throughout its long history a matter of experimentation, with new species being constantly spawned and thrown into the ecological arena to compete and, more often than not, become extinct.

Viewed this way, is simply the last surviving twig on a vast and intricately branching bush, rather than the sole occupant of a summit that has been laboriously climbed and, by extension, somehow earned.

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.

A variety of incomplete or broken fossils from the period between about 2.5 and 2.0 mya have been placed in the category of “early .

It had long been known that human beings physically resemble the primates more closely than any other known living organisms, but at the time it was a daring act to classify human beings within the same framework used for the rest of nature.

Linnaeus, concerned exclusively with similarities in bodily structure, faced only the problem of distinguishing is a matter of active debate.

The design of her pelvis and feet are suggestive of bipedal locomotion.

However, other skeletal elements indicate that she spent much of her time clambering through the branches of trees.

The molecular clock concept is based on an assumed regularity in the accumulation of tiny changes in the genetic codes of humans and other organisms.
