REASONING AND INTERPRETATION – Practice questions 1. Understanding the ecological mechanism that causes extinction is fundamental to conservation as not all organisms are threatened by the same factors. A total of 1012 threatened bird species in 95 families were studied to see how they were threatened by different factors: · habitat loss · persecution by humans and introduced predators · other factors (introduced competitors‚ hybridization and disease) and unknown risk factors. Scientists investigated

incisors‚ canines‚ premolars‚ and molars (upper +lower jaw) multiplied by 2 would equal to the total number of teeth present in the mammal. The dental formulas for these three species: coyote (Canis latrans)‚ deer (Odocoileus virginanus)‚ and human (Homo sapien) are all different. The coyote had the dental formula of 3-1-4-2/3-1-4-2 (x2)‚ which produced the total of 40 teeth. The deer had the dental formula of 0-0-3-3/3-1-3-3 (x2)‚ which equaled to 32 teeth. The human species had a smaller number of

(Section 10.1‚ pp 222-224) Figures to review: 10.1‚ 10.2 Biological evolution • Biological evolution is defined as any genetic change in a population that is inherited over several generations. These changes may be small or large‚ noticeable or not so noticeable. Species • the major subdivision of a genus or subgenus‚ regarded as the basic category of biological classification‚ composed of related individuals

In an ancient site in Israel called Gesher Benot Ya’aqov burned wood and seeds were discovered dating back to 790‚000B.C. Findings in the Transvaal‚ South Africa‚ show that Hominids were making fire far before previously thought.

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.

human as vegetarian is centered on the characteristics of the human body compared to carnivorous animals. It argues that because humans don’t have claws or pointed teeth we shouldn’t eat meat. However‚ I found that the digestive and dental system of homo sapiens serves as an example on omnivorous adjustment because the incisor teeth and canine are good to tear cooked meat into pieces‚ whereas the molars are needed to grind vegetable matter. Furthermore‚ vegetarians argue that carnivorous animals have

Evolution of human intelligence The evolution of human intelligence refers to a set of theories that attempt to explain how human intelligence has evolved. These theories are closely tied to the evolution of the human brain and to the emergence of human language. The timeline of human evolution spans approximately 7 million years‚[citation needed] from the separation of the Pan genus until the emergence of behavioral modernity by 50‚000 years ago. The first 3 million years of this timeline

their nature‚ these have not been preserved to any great degree. Surviving artifacts of the Paleolithic era are known as Paleoliths. Humankind gradually evolved from early members of the genus Homo such as Homo habilis — who used simple stone tools — into fully behaviorally and anatomically modern humans (Homo sapiens sapiens) during the Paleolithic era. The Neolithic Age‚ Era‚ or Period‚ or New Stone Age‚ was a period in the development of human technology‚ beginning about 9500 B.C.E. in the Middle

characterised by speciation. The term speciation refers to “the formation of new and distinct species in the course of evolution”. Recently‚ experts in the field of evolution have given special emphasis to the new and most controversial issue of Homo floresiensis. Homo floresiensis (known as the Hobbit Man and LB1) is the little bodied and an extinct species that was discovered from a fossil and simple stone tools in 2003 on the island of Flores in Indonesia. Scientists indicate that the fossil belongs to

Religion and Wisdom go hand in hand. That one is unable to thrive without the other. In this Explanatory Synthesis I will discuss Karen Armstrong and Robert Thurman beliefs and differences about the two subjects. I am going to be using the section “Homo Religiosus” written by Armstrong and the section “Wisdom” written by Thurman to compare the author’s views. Robert Thurman is one of the first Americans to be ordained as a Tibetan Buddhist monk. He is a scholar‚ translator‚ activist‚ and lecturer
