Furthermore, some of the fossils attributed to O. It should be noted, however, that indisputably bipedal hominins e. Currently, the debate over whether or not O. Thus, its evolutionary relationships with later hominin species are not well established. While some researchers are convinced by the features in this species that seem to indicate that it practiced bipedalism, others remain skeptical.
In addition, due to the fact that O. Drawing connections between O.
The habitats in which O. Evidence from non-hominin animals found at O.The Psychology of Security. I just posted a long essay (pdf available here) on my website, exploring how psychology can help explain the difference between the feeling of security and the reality of security..
