Laetoli Foot Prints Analysis

Leaving the area of the “Infrasound encounter”, I venture down a long narrow trail, investigating an area on the lake shore. Lurking in this area were at least three Bigfoot that I would soon encounter. The following is this account taken from my book “The Bigfoot Field Journal – Volume 1.”

What are common motifs found in cave paintings such as those at Lascaux and Altamira? Summarize the current theories about their original meaning and purpose

We share almost 99 percent of our genetic material with chimpanzees. Yet we have several traits that are very different. Two legged walking, or bipedalism seems to be one of the earliest of the major hominine characteristics to have evolved. To

The Australopithecine are some of the earliest known hominids and they embody many characteristics that are associated with bipedalism. Bipedalism is a highly specialized and unusual form of primate locomotion that sets modern humans apart from all other living primates as we are the only extant obligate bipeds. Many evolutionary biologists and paleoanthropologists have devoted innumerable research hours to attempting to understand this unique form of locomotion and how it evolved. A number of interdependent morphological adaptations occurred over a long period of time to solve challenges posed by habitual bipedalism. As a result, there are obvious differences that exist between early and late hominin species.

They found that Au. ramidus had very similar characteristics to Sahelanthropus Tchadensis an ancestor that dates to 6-7 million years ago. Ardi had a foot that was primitive and had an opposable big toe which was most likely used to grab on branches. She also had a long and curvy spine just like humans. Its pelvis was large like those of apes and had short and broad shoulders suggesting it had a lower center of mass and could possibly walk on one leg at a time. But it is also thought that it was still spending a lot of time in the trees as well. Thus, why it is thought to be intermediate form of bipedalism it lived in both worlds, walking upright, and climbing trees, equal success in both biospheres. Although Ardi is not the connection to apes it still served to prove that the ancestor of apes was a lot more primitive than we believed. There are still several questions to be answered in this puzzle called our ancestry. It may seem that more questions arise as more clues are found, but that is science, there would be no intrigue left if all questions were

In the article “Born to Run” by Adam Summers, who is an assistant professor of bioengineering and ecology and evolutionary biology at the University of California, Irvine, the author states that throughout time bipedalism has evolved to benefit endurance running. Summers also claims that bipedalism modern humans have differs from the one our early ancestors had. The author relies on the research by Dennis M. Bramble and Daniel E. Lieberman that have improved the understanding of human bipedalism and its evolution. According to Summers, the corrections made by Bramble and Lieberman’s research helped to draw a more accurate picture of an early human.

Through the years, the recurring debate of one creature’s existence has distinctly proven to stand out amongst many others. At a first glance, the idea of this creature, frequently regarded as bigfoot, seems preposterous and even a tad bit foolish. However, it is not completely absurd to believe that a large, biped humanoid, and ape-like creature is roaming the acreage of America. With substantial evidence provided by numerous credible sources, there is no room for doubt or for a struggle to believe that bigfoot does certainly not only exist, but thrive on earth as well. There have many accounts on the specifications of bigfoots characteristics, however, those do not point towards a reason for ambiguity. Bigfoot can be found in mountains, creeks,

First, evidence from the hominid fossil Ardy and archaeological evidence from the same area where Ardy was found points to the evolution of bipedalism in a woodland environment. This goes against the previous assumption that bipeds adapted to a more desolate environment. Additionally, it was also previously believed that bipedalism started with organisms that walked on two legs and their knuckles as a today’s chimp walk. However, there is no evidence in Ardy’s bones that it ever walked using its knuckles. On the other hand, Ardy possesses a short, broad hipbone which allows for bipedalism, but also a much longer lower half of the pelvis which would be more useful for climbing. Consequently, while Ardy could walk on two legs, it could not walk as well as future bipeds such as the fossil Lucy or modern humans. Lucy is often described as “the ape who stood up” and is further down the evolutionary track toward modern humans. This evolutionary adaptation to stand and walk on two legs opened great doors for humankind. Most important was the fact that walking on two limbs rather than four freed up our very special hands and empowered humankind to build tools and reshape the world as no creature could

One would think such an endeavor would be heralded by the “Bigfoot Community” at large, disappointingly it was not. The monumental effort but forth was placed under attach almost immediately once word circulated that such a study was underway.

The Ardipithecus ramidus foot shows key characteristic features of bipedality. Whilst there is evidence to show support for bipedalism it is hypothesised that was an occasional form of locomotion used less commonly than arboreal methods. This can be seen through the

What did the early American pioneers see when traveling the uninhabited wilderness of the early 1800’s? Could they have be seeing a black bear standing momentarily on its hind legs or was it actually what we now call Bigfoot today (“The Canadian Encyclopedia”). The origin of Bigfoot dates even further back to Native American myths portraying a large aggressive ape like animal walking on its hind legs eating children and animals (“New World Encyclopedia”). Since then there have been thousands of reports of supposed Bigfoot sightings including footprints, photos, videos and the actual carcass of a deceased Bigfoot. For over 80 years scientist have been discrediting the thought of the existence of Bigfoot, but throughout time scientist have

The first piece of evidence that led the Lartets to draw conclusions about where the Cro-Magnons originally lived is the layering of the talus that was found above the skeletons. According to the reading “The Cro-Magnons”, “Lastly, above these different layers, and all over the shelter itself, lay the rubbish of the talus 3 (4 to 6 meters thick), sufficient in itself, according to what we have said above about its mode of formation, to carry back the date of the sepulture to a very distant period in the Prehistoric Age” (Lartet and Lartet 1). In other words, the layer of talus found above the skeletons lead paleontologists to think that these people were alive in prehistoric times. While paleontologists were not able to immediately figure out where the Cro-Magnons originally lived, this evidence did narrow the search, as it gave researchers an idea of the area that people in that time preferred to live by. Thus, the layer of talus above the discovered skeletons helped the

In the study by Hunt, it is argued that the evolution of bipedalism was an adaptation by early hominids used in the gathering of food not only from otherwise hard to reach arboreal sources but also from “terrestrial” sources as well (Hunt 1996). The use of bipedalism in the gathering of food allowed early hominids and more modernly, though in

Approximately 4 million years ago a wonderful evolutionary phenomenon was happening in Africa. Early hominids, man’s ancestors, were beginning a giant leap in their evolution. These hominids were moving out of the forest and beginning to walk upright, out on the open plains (Fagan, 98). This change from quadrupedalism was the most significant adaptation that ever happened to these early hominids. It caused many adaptations that make man what he is today. This process occurred in early hominids for many different reasons, each reason helping to perfect the upright walking posture. Bipedalism is thought to have occurred because of changes in environment, feeding habits, thermal regulation, and

There has been much debate concerning the origins of bipedalism. Bipedalism, or the ability to move on two legs (eLucy, 2007) was said to have emerged due to climate change in East Africa, for sexual display purpose, to reduce exposure to sunlight, the need to use weapons and tools and many more (NOVA, 2013). There are numerous arguments associated with bipedalism as no one can be entirely sure as to what constituted to the emergence of this trait, which was first present in hominins Australopithecus Afarensis. Anthropologists claim that there is a missing link in the evolutionary lineage that makes it hard to confirm the real cause of bipedalism emergence. However, there are some models which are widely accepted by scientific world, such
