The Evolution of Homo
Many people believe that humans evolved from neanderthals, but it is known that the latter was not man’s predecessor, but rather a totally different sub-species that competed with the former for survival. It is safe to say that the closest living things that resemble a neanderthal would be gorillas and chimpanzees, big, burly, and strong. Humans are frailer, smaller, and weaker than both, and thus inferior to a neanderthal. The latter were amazingly skillful at weapon making and hunting, and were around much longer than the early humans (McDougall, 2009). Much like a jackrabbit to a cougar, Homo sapiens must have had something that neanderthals didn’t, the big question is, “What was it?”
Dr. Bramble had studied the skull of early hominids and found something astonishing. The back of the skull of our predecessor Australopithecus afarensis was smooth, while the back of the skull Homo erectus had a notch in the back of it (McDougall 2009). Surely something had to fit in that notch, and something did. It was something that can only be found in animals that run, such as horses and dogs, not in pigs and chimps. What lies on the back of the skull of such running animals is a stabilizer ligament, the nuchal ligament, that is only useful in stabilizing the head when the animal is moving fast, much faster than a trot let alone a walk. This is only just one piece of evidence out of many that the genus Homo must’ve been made for moving fast.
Dr. Bramble teamed up with Harvard professor Dr. Daniel Lieberman to further explore the differences between the anatomy of H. erectus and A. afarensis by studying the difference between humans and chimps respectively. Bramble and Lieberman found that there are a number of ligame...

...shin splints (painful shins due to great force). All of these injuries can obviously be seen to be caused by the use of conventional running shoes. According to Dr. Paul Brand, “we could wipe out every common foot ailment within a generation by kicking off our shoes (2009)”.
McDougall also writes of a young Alan Webb, America’s best miler. Webb was very injury prone in terms of lower legs and feet. Essentially his coach had him run barefoot after practice to strengthen the muscles in the foot. Soon, the arch of his foot got stronger and higher, and he was injury free. He later went to become one of the fastest indoor high school milers, and run an American record in the mile.
Nowadays, many running shoes manufactures have spent billions of dollars in coming up with shoes that mimic running barefoot, and more people are turning towards this barefoot running trend.

Biodiversity on Earth: The Evolution of Homo Sapiens Essay

- Biodiversity Earth is home to millions of different species, but only one dominates. Us, the Homo sapiens. Our intellect, innovations and activities have altered our planet. Our cleverness, our ideations, and our activities now drive all the global problems we face. Since the beginning of Homo sapiens, we have greatly altered the supply of nutrients, the environmental composition, and diversity. During this time we have continuously added so much pressure that, in the next century, we may fall out of the envelope of which many species evolved....   [tags: little ice age, intellect, innovations]

Alternative Genetic Influences On H Sapien Evolution Essay

- Alternative Genetic Influences on H. sapien Evolution The DNA (deoxyribonucleic acid) of all the people living in our world today contains a record of human history. Just like a family tree, our DNA shows how we are related to our relatives and takes us back in our history to those that came before us. Most of us have old, black and white photos of some of the folks on our family tree and we find, for the most part, that those ancestors looked fairly similar to us. However, scientist are now finding that if you could obtain a photo from members of your family tree over 40000 years ago you may find it a bit difficult to point out any similar features....   [tags: Human, Human evolution, Archaic Homo sapiens, DNA]

Essay on Ancient History: Neanderthals to Homosapiens

- NEANDERTHALS TO HOMOSAPIENS Neanderthal the most recent archaic human, who was introduced to this world between 300,00 and 100,000 years ago then after many years were replaced by humans between 35,000 and 24,000 years ago. Neanderthals inhabited Eurasia from the Atlantic regions of Europe eastward to Central Asia and from as far north as present-day Belgium southward to the Mediterranean and southwest Asia.” (www.britannica.com). Human populations that were very similar to Neanderthals lived in eastern Asia and Africa....   [tags: arcaic human, evolution, homo sapiens]

Human Language Essay

- The emergence of human language is associated with the Homo sapiens period. This is estimated to be about 200,000 years ago, when this species came into existence. However, the emergence of language was between 30,000 and 100,000 years ago. In explaining the question of where the language emerged, it will be appropriate to focus on the remains of the Homo sapiens who existed between these periods of time. As it will emerge from the discussion, more recent Homo sapiens remains have been unearthed in France, Australia and China....   [tags: communication, homo sapiens, evolution]

The Superior Temporal Gyrus Of The Left Cerebral Hemisphere Essay

- The Wernicke’s area is an area located within the posterior aspect of the superior temporal gyrus of the left cerebral hemisphere (Aboitiz 1997), that is, an area in the back of the left side of the brain. The Wernicke’s area is associated with speech recognition and comprehension, and working in unison with Broca’s area (the part of the brain responsible for speech production), allows for higher forms of communication between individuals (Binder 1997). The development of the Wernicke’s area and language as a whole, is believed to have had a huge impact on the evolution of Homo species, as it provided a means of communication and co-operation between individuals, giving a unique advantage ov...   [tags: Human, Human evolution, Archaic Homo sapiens]

Modern Humans Are The Only Ones Who Exists Today Essay

- In the Pleistocene Era, hominins have been expanded rapidly in terms of survival, such as availability of food resources, migrating and how they defend their territories. Then, this has been lead hominins to develop intelligence and create a wide variety of tools. However, there is no specific evidence or answer to, how did human beings evolve and where did they come from. Environmental conditions or pressures have been played importantly, that contributed to the selection of the genus Homo in Africa, Europe, Asia, Australia, and there is an anatomical evidence over the past one million years, culminating in our modern genome; leads to developing human cognition and explains why modern human...   [tags: Human, Human evolution, Archaic Homo sapiens]

Different Traits Of Homo Sapiens Essay

- Introduction: One of the most distinct traits of Homo sapiens is the exceptional size of its brain relative to other species with a brain mass that is markedly larger, with the human brain three times as large as would be expected by the proportions of other primates (Marino, 1998). In particular, the association areas in cerebral cortex of humans responsible for cognitive functions such as ‘language, theory of mind, reciprocal exchange… the use of tools [and] cultural learning’ is significantly larger than those found in other primates (Rilling, 2006, p....   [tags: Human, Human evolution, Primate, Homo erectus]

Essay about Homo Sapiens and The Ecological Hypothesis

- It is obvious that the human brain has become more susceptible to knowledge over the course of time but what remains undetermined is what the cause of the evolution of the brain is. Light has been shed on many possible theories that potentially explain this morphological evolution, however, two theories seem to draw the most attention: the ecological hypothesis and the social brain hypothesis. For reasons involving food scarcity, early Homo sapiens evolved in order to keep themselves sated and survive, according to the ecological hypothesis....   [tags: human brain, evolution, theories]

The Neanderthal Fossil And Homo Sapiens Essay

- The Neanderthal fossil was first discovered in 1829 but it was not until 1856 that conclusions were made. Originally they were not categorized as possible human ancestors until further discoveries of fossils were discovered in the mid-19th century. The taxonomy of the Neanderthals has been highly debated between homo neanderthalensis or homo sapiens because of their close physical similarities with humans, eventually they were ruled as a subspecies of homo sapiens. The similarities between Neanderthals and homo sapiens was traced back by DNA from 350,000 to 500,000 years ago identifying a common ancestor between the two taxonomies....   [tags: Human, Neanderthal, Human evolution, Pleistocene]
