Cranial capacity

has been used on those affected by dementia and Alzheimer's in hope of bringing these subconscious memories back. ("Ellis, 2014") Listening to the same song while studying and testing has also proven to increase performance through enhancing memory capacity. ("Music…

The study of the evolution of human beings often presents many challenges. One of the main challenges is the limited evidence and the constant emergence of new forms of evidence. From time to time, scientists encounter the challenge of naming the fossils and putting them into their appropriate species. In this paper, I am going to discuss the Homo erectus, Homo Heidelbergensis, and Archaic Homo sapiens. The paper will make comparative analyses of the individual species and point out why I…

technological innovation that came with evolution. H. sapiens have a larger brain than other primates, as well as speech capabilities. The skull of H. sapiens are high and vaulted – a higher forehead than the H. erectus, which provides a large cranial capacity. The skull is also rounded in the back and eye sockets are square rather than rounded. Interestingly; humans are the only species with a protruding chin. Humans have smaller teeth and do not have the pragmatism and heavy brow ridges of…

1. What factors should be considered to provide maximal protection when people are exercising in the cold? To avoid excessive heat loss, our bodies use peripheral vasoconstriction, nonshivering thermogenesis, and shivering, which is usually not enough. Peripheral vasoconstriction We must also rely on behavioral responses like huddling behavior and putting on more clothing to help insulate our deep body tissues from the environment. During aerobic exercise, clothing insulation and exercise…

H. erectus evolved from A. afarensis and lived from 1.9 million years ago until 300,000 year ago. (Kottak 9.1 Recap 189) A complete fossil of H. erectus found in West Turkana showed that the species had a cranial capacity of 900 cubed centimeters and had a modern body shape and height. (Kottak 182) The H. erectus was essentially modern as it was much larger and had longer legs than earlier hominins. It had a modern skeleton with a body and brain size more relative…

evolutionary stage; they are more like dark – skinned ‘savaged’ than normal, law – abiding white people” (Raffle and Brown, 2011 p.29). Moreover, Lombroso declared, that common features for criminals are “thinning hair, lack of strength and weight, low cranial capacity, receding foreheads, highly developed frontal sinuses…darker skin, thicker, curly hair, [and] large or handle-shaped ears” (Lombroso cited in Bowling and Philips, 2002 p.57). Furthermore, Lombroso acknowledged, that “white…

Syndrome Recent febrile illness, likely viral. Positive for bilateral weakness, numbness, paresthesia, finger dysesthesia. Severe hyporeflexia or areflexia. Lack of well demarcated sensory level (Andari, 2016). No evidence of damage to cranial nerves, particularly cranial nerve 7. Relatively rapid progression, 5 days since illness as opposed to several weeks (Andari,…

Hominin expansion throughout most of Africa occurred with Australopithecines, Paranthropus, and early Homo habilis. Each species was advancing, and adapting to their various habitats. However, a new homo was entering the playing field, which was not only biologically modern but was capable of creating tools. This new species is known as Homo ergaster/erectus, and they were on the verge of breaking out into new territory. This group would soon leave the cradle of Africa and traverse to Asia,…

The use of tools have been an essential part of human history and culture, even before modern humans evolved. Being made up of many layers, tools are valuable sources of evidence that reflects the dexterity and cognitive abilities that the hominid species possesses whether extinct or still living. In this essay, I will be discussing the impact of tools use and the effectiveness it had on our evolutionary history and cultural practices. Developments towards human evolution that aided tool making…

increase in technological, economic, social and cognitive behavior that occurred and then the ability to expand to different regions of the world came. These radical changes were triggered by neurological mutations that allowed for greater cognitive capacities. The environment of Africa allowed for the…
