In order to properly explain how the multi-layered factors at play in this region determined human evolution--through the stages of bipedalism, the emergence of various other hominins such as Sahelanthropus tchadensis and Homo erectus, before finally Homo sapiens arrived--we need to understand the interplay between global climates and tectonic activity.
Small tweaks to a gene that makes a protein important for skeletal development may have led to the big toe and helped shape the human foot for bipedalism (SN: 2/6/16, p.
For instance, it is unlikely that it is Jesus' bipedalism that should be imitated, as this feature is too broad, or that his place in history as a first century Galilean should be imitated, as this characteristic is too inaccessible (Barrett, 2013).
CM AND DM: You use the concept on lameness in Hyperobjects, and we'd like to discuss it further, because it is so compelling in relation to the notions of bipedalism and the carbon footprint, as well as of Oedipus's swollen foot and Achilles' heel.
In addition, Australopithecus, the suspected first toolmaker mentioned earlier, also left us the first record of upright walking or bipedalism.
Objective: "Understanding the locomotor behaviour of our Miocene ape ancestors is critical to reconstructing the evolution of walking on two feet, or bipedalism.
The book then reaches gradually backwards in time, discussing how bipedalism moved us out of the trees and onto the savannahs; convergent evolution of different classes of flying animals; the influence of swimming on the development of vertebrate organization and fins-to-limbs; how animals' needs for movement logically produced a head-to-tail axis and widespread bilateral symmetry; and even how the advent of a complex centralized nervous system developed in service to locomotion.
This effect facilitated the maintenance of blood pressure during the evolution to bipedalism under the low sodium diets, prevalent during human evolution [98].
In this genus, as in other desert inhabitants of the family Heteromyidae, the presence of bipedalism has direct consequences on the speed of movement and leaping distance (Price, 1993).
Bipedalism emerged with the hominid precursors of Homo sapiens.
