Anth 368 Midterm 1.What roles do plate tectonics play in the geomorphology of Pacific Islands? The earth’s crust is made out of plate tectonics. Each plate has a defined boundary and direction it moves. The plates in Earth’s crust perform two actions; they submerge under each other or they spread out. The Pacific Plate is the largest plate and it borders around many plates. The Pacific Plate moves northwest. New crust is formed from magma outpours‚ which are a result of the zones spreading.

THE WORLD That’s a rather vague question. The earliest true humans were Homo erectus. These early humans only used stones to begin with. Their earliest technology was called Oldowan and involved breaking smooth‚ rounded pebbles from rivers in rather a crude fashion to get a sharp edge to cut with. Later they developed a more sophisticated technique‚ creating a large‚ hand-held item shaped rather like a teardrop. It had two sharp sides coming to a point and one dull‚ rounded side which the

Introduction to Hominid Evolution Hominid evolution is the theory of the origins of the human species (Homo sapiens). Current understanding of human origins is obtained largely from the findings of paleontology‚ anthropology‚ and genetics. Of all primates‚ humans share particularly close affinity to other members of a group known as hominoids‚ or apes. Humans and their immediate ancestors‚ known as hominids‚ are notable among hominoids for their bipedal locomotion (Using two legs for walking)

People care more about murders‚ airplane crashes‚ etc. instead of the exploding populations or the growth in the amount of nuclear weapons that exist. Because of this‚ our environment starts to deteriorate. The environment will continue to deteriorate‚ and such events will be out of control

Representatives of homo erectus gradually replaced them around a million years ago when they also spread across Africa and into Europe and Asia. Homo erectus gave way to homo sapiens around 100‚000 years ago. The first homo sapiens formed the Bushman culture of skilled hunter-gatherers. Around 2‚500 years ago Bantu peoples migrated into Southern Africa from the Niger River

Evolution is the change in the inherited characteristics of biological populations over successive generations. Evolutionary processes give rise to diversity at every level of biological organisation‚ including species‚ individual organisms and molecules such as DNAand proteins.[1]All life on earth is descended from a last universal ancestor that lived approximately 3.8 billion years ago. Repeated speciation and the divergence of life can be inferred from shared sets of biochemical and morphological
