Bipedalism is very important for human evolution and development because the upright stance adopted by early hominids allowed gave them a number of advantages. Firstly the creature could have both hands free to carry things; to use tools; to dig; cut; climb and to fight. The…

Disadvantages are that the eyes are now further from the ground, so further away from tracks being followed, or from low growing food. Also, by standing tall, the person is more likely to be seen at a distance by enemies and predators. As hominids moved out of Africa into cooler climates they were at a disadvantage as more of the body surface was exposed to colder weather.
The Dikika infant was a three year old (Sloan) member of the Australopithecus afarensis group, and was found encased within Ethiopian sandstone. The baby is apelike in her upper body, but human like below the waist. She is very small, and is likely to have been carried a lot of the time. Her skull supports only the same space that a three year old chimp’s brain would, so, in evolutionary terms, bipedalism seems to have come before great brain development. Jenk describes how some argue that the ape like, tree climbing facilities exhibited in this specimen may simply be inherited, and were not necessarily used. Others say that these creatures used both humanoid bipedalism and ape like methods of locomotion.
This is the skeleton of a very young child. This means that the skeleton does not exhibit the changes that would have occurred in an adult, because certain muscles were being used in preference to others. What is needed is a complete adult skeleton before a definitive answer can be arrived at with regard to the preferred method of

ANTHROPOLOGY ESSAY QUESTION Renowned anthropologist theorist and researcher Sherry B. Ortner (1974) has made a critical and in-depth analysis of women within biological and cultural perspective, on the foundation of which she has endorsed the relationship between woman and man on the one hand, and between woman and nature on the other.
According to the Savanna-based theory, the adoption of the upright posture and the subsequent walking or standing on the two hind appendages was caused by the transition from the lifestyle on trees to erect walking on the savannah (Strickberger 474). Among other scholars, Elizabeth Vrba supports this theory.
The relationship between phenotype, genotype, and natural selection is essential to the knowledge of heredity and development organism. Phenotype refers to the traits that an individual has, and is determined by the genotype and the environment. Natural selection comprises of the process which results from differences in reproductive successes among unique individual phenotypes living at a given generation and eventually resulting in a biased representation of genes at the next generation.Natural selection acts on phenotypes because differential reproduction and survivorship depend on phenotype.
Anthropologists in general look at cross-cultural differences in social institutions, cultural beliefs, and communication styles. In fact in recent years with the growing globalization, this subject has gained much more importance. Knowledge about human diversity is helpful especially in the case of global organizations.
Genic activities, as argued in biological anthropology, will bring about different outcomes under different conditions. Most voluntarily observable characteristics are influenced to a lesser or greater extent (Merrell & Ingersoll, 1962).
They attribute this cooperative behavior to rainforest chimps, and contest the argument that cooperative behavior originated only after the change of habitat from the rainforests to the savannahs.
This topic is of obvious importance in the ongoing
heory of “Out of Africa” which presents the fact that the present human generation has mainly evolved from Africa and this evolution actually took place 100000 to 200000 years back.
Answer: Anthropology is a subject which deals with the evolution of human beings and studies
Additionally, the hunter-gatherers built villages and towns. This led to change of their environment by adoption of specialized food crop cultivation. This led to excessive food production, which in turn led to trade in surplus
They became extinct; it is not in doubt their close semblance to the early human ancestors. Experts in Hominid research refer to them as man-apes and also ape-man this is because they have features of the two groups,
