Homo erectus

this age we see that the assortments of guys and females contrasted marginally, because of bone structures. Patterns in the division of work were built up ahead of schedule in advancement and got enhanced with the development of the huge brained Homo erectus. A greater cerebrum required a size increment in the conception channel and female pelvis. These and other physical changes overstated sex contrasts in the division of work with respect to the chasing versus get-together stages. This time of…

Archaologists have only found skeletal remains of Homo sapiens in the New World, however Homo erectus and previous life forms have been found in the old world, implying that Homo sapiens crossed into the New World in the time of the ice age. The only explanation as to how the migration occurred is a land bridge connecting Northeast Asia to Alaska, however there is no land connecting the two in present day, only a strait that is fifty six miles wide at its narrowest point, and approximately 180…

From both the article and the textbook, some of the unique qualities of humans are its bipedalism, large brain, complex language, and the ability to forge tools. Of all the traits listed above, bipedalism is one of the most vital. Not only was it essential for the survival and expansion of our species, but according to Darwin it is considered a key force for human evolution. (Ironically enough, one of the major health problems that people face today is living a sedentary life style.) Before we…

Every culture has a different way of “being.” They have different traditions and customs that are passed down from generation to generation. Alongside all of their practices and beliefs, every culture has their set of norms. A norm is an expected standard of behavior and belief within a given culture that is usually implicitly passed from one generation to the next. Today, over two-thirds of adults in the United States are overweight or obese. In order for a person to gain enough weight to be…

1. Homo sapien, our direct ancestors, emerged approximately 300,000 – 100,000 B.C.E. They were larger and more advanced than their previous ancestors, hence why they were known as the “wise human”. Homo sapiens were cave dwellers and hunters, much like homo habilis and homo erectus. Homo sapien was not known as the “tool-making” human like homo habilis was, but homo sapiens hatchets and needles made the stone and bone tools of homo habilis look quite juvenile. Homo sapien walked upright, a…

Since the emergence of the genus Homo, the hominins went through great patterns of evolution over generations. Through series of adaptations, the genus Homo spread in various geographic locations and eventually emerged as anatomically modern humans. With the allele frequency changes that evolved in the genus Homo, there is key evidence that microevolution led to macroevolution. From speciation to extinction, the modern synthesis helps us explain not only the mechanisms of evolution and the…

Until 11,700 years ago our earth had been in the Pleistocene Epoch, incorporating an evolutionary surge that lead to Homo Habilis, who lived from about 2.1 to 1.5 million years ago(2). By the peak of this duration the global temperatures on earth dropped by about 5oC, plunging the entire planet into an ice age, creating vast glaciers miles deep that expanded across limitless amounts of land, locking hordes of water into impenetrable sheets of ice. However, this gave a few species on earth a…

The first mammals evolved from mammal-like reptiles at the end of the triassic period. Therapsids, or mammal-like reptiles, is an order of reptiles that lived in the Permian and Triassic Periods before going extinct in the mid Jurassic Period. It is difficult for scientist to determine when the divide between therapsids and mammals occurred. Early mammals had small, mouselike forms. Very few were large, because dinosaurs were the unquestioned dominant land animals on earth. The ecological niche…

of cranial capacity), roughly equivalent to modern apes, like the chimpanzee (at 400-500cc), and the gorilla (at 500-700cc). The expansion of the hominid brain appears to have only really begun with the genus Homo. Between 2 million and 700,000 years ago, the size of the brain of Homo erectus actually doubled.…

Evolution is the change in a period over time. Scientist use evidence of evolution to prove that there was a change in organisms over time. If the evidence is present, scientist would come up with theories that are reasonable enough to have support from the pre- historic time frame. The lab is to show the people how living things came to be in the present day. Including how fossils as evidence explain why there maybe certain functions were used in the early stage of an organism. Hypothesis: If…
