Neanderthal

The Journey to Populating the Earth Hominid began to populate the earth millions of years ago, from Africa and eventually spread out to all of the continents on Earth. The journey took millennium through errors and trials of survival and social organizations. Through Homo sapiens’ excellent adaptation, cognitive revolution and complex social organization, we were able to spread out as much and as fast as we did and dominated the entire planet. The harnessing of fire played an extremely…

sapiens to become faster, obtain wider food sources, forage, and escape climatic conditions, and create better tools and technology for survival. These advanced qualities allowed greater resource competition against coexisting species, such as the Neanderthals, outliving them in the process. The act of energy conservation in the human body can be attributed to bipedalism, because “more ground can be crossed with less energy, and this would be important in moving between widely scattered patches…

Scientific method not only links to bigger contexts and objectives for this course, but also enhances our understanding the evolution in human populations. From race to cultural identities, scientific method greatly acknowledges the evolution of our biological adaptations and diversity. We put great emphasis on the scientific method because it never seeks for absolute, definite answers. Instead, it opens up new possibilities of stronger evidence to support the human evolution. With many…

DISCUSSION OF THE CAUSES OF HUMAN SKIN COLOR VARIATIONS The variation of human skin color is a complex phenomenon which have not yet been researched and studied conclusively. However, various researchers and academicians have given insight about the possible causes of this important trait. Different researches using people from different parts of the world, evaluation of their environments and diet and to some extent DNA analysis have given a variety of possible causes of human skin color…

Charles Darwin is very well known for his theories on evolution and most importantly his three principles of evolution by natural selection. Darwin’s first principle is that a variation exists within populations. Some examples of variations include body size, bone structure, tooth size, hair thickness, shape of the rib cage and position of the foramen magnum. In Evolution, Dr. Alice Roberts provides examples of early hominins and how their physical makeups were reconstructed by archeologists…

Genetic Engineering, Cloning, and Stem Cell Research Research over the last few decades has enabled scientists to identify the genes that compose the human body. Although this is a fascinating branch of scientific research, the numerous uses of genetic engineering carry with them many ethical questions. Some of the possible uses of gene manipulation listed by Boss (2013) include: cloning to produce or replace children or to create children with special qualities, manipulation of genes in order…

characteristics these being influenced by genetic or hereditary characteristics. This was one of Lombroso's largest, and most disproved theories, that individuals with more primitive appearances such as broader foreheads or more prominent chins, similar to neanderthals. More popular today though are biological traits that have the greatest effect on neurological traits. These theories attempt to distinguish among individuals on the basis of structural, functional, or chemical differences in…

In today’s fast pace society no one is exempt from the demands of work, and the resulting fatigue. Nowhere is this better illustrated than in the life of a nursing professional. Nurses are scheduled to work 12-hour shifts as a matter of course. Then, to make a 40-hour workweek and obtain benefits they work a fourth 12-hour shift. Already into overtime, the nurse will volunteer for even more hours to satisfy their need to care for people in their charge. Also, the particular needs of the case or…

People have existed on earth for billions of years. Many species of animals and fish that do not have males as a part of their community, but instead, they have the ability to reproduce asexually. Even though males are not necessary for survival, Matt Ridley argues using different business references and nature examples to prove men are similar to animals by nature because that is how women bred them to be. Ridley uses a different style of writing to further prove his point of the essay. The…

In 1735, Carolus Linnaeus, proposed a system of classification for all plants and animals in his book Systema Naturae, and used his system to give us the name of Homo sapiens which literally means wise man. In this system, each genus could have many different species, and each genus is part of larger categories of living things. In Linnaeus’s system, he categories homo as our genus, but we are also a part of the primate order, which is a category much larger than our own genus. Linnaeus…
