Paciulli FINAL BIO 181 NCSU, Exam Questions and answers, 100% Accurate. VERIFIED. To the west of Wallace's Line in Southeast Asia are organisms related to Asiatic species. To the east of the line, there is a mixture of species of Asian and Australian origin. This is an example of: - -biogeography Two members of the initial Amish migration to Pennsylvania in 1744 shared the recessive allele for Ellis-van Creveld syndrome, which results in a long narrow chest and shortening of the limbs. More Amish people have these traits than the surrounding non-Amish population. This is an example of... - -the founder effect Evolutionary changes within a species are most accurately referred to as: - -microevolution Our ancestors had much bigger jaws than we do, which helped them chew a tough diet, tear apart meat, etc. Their teeth also wore down quickly. Wisdom teeth (third molars) grew later in life, and helped our ancestors continue to eat. Today, ~35% of people are born without wisdom teeth. This is an example of: - -evolution The idea that most speciation is slow and uniforms is known as: - -gradualism Drongo birds live in central Africa. One population is found in evergreen rainy forest areas, while another population is found in open grassland areas. The two populations live in two different habitats 150 feet apart, and do not interbreed. The _____ Species Concept best explains this phenomenon. - -ecological Selection pressure throughout earth's history has been most often exerted by... - -the environment The first step of the scientific method is _____ . - -observation People who are wealthy, and only marry people who are wealthy who have blond hair and blue eyes are practicing a form of _____ mating. - -assortative Non-poisonous king snakes mimicking poisonous coral snakes is likely due to _____ - -biogeography All wasps have stingers. This thing in my hand is a wasp. Therefore, this wasp can probably sting me! This is an example of _____ reasoning. - -deductive We said that each level of life ... - -has emergent properties The only source of new genetic variation is / are _____ . - -mutations Although Jean-Baptiste Lamarck's work was important in the development of evolutionary thought, he was wrong because he believed that characteristics were _____. - -aquired The large antlers of moose help them fight other males, to gain access to females. - -intrasexual selection Smaller teeth in all modern humans as our diets became less coarse. - -directional selection Two distinctly different beak sizes occur in a single population of black-bellied seed crackers (a finch species that lives in Cameroon, West Africa). The small-billed individuals feed mainly on soft seeds, while the large-billed individuals feed mainly on hard seeds. - -disruptive selection The smallest unit capable of carrying out life functions is a / the - -the cell Blue-footed boobies (a species of bird) select mates after an elaborate courtship display. They will not mate with other boobies. Indicate whether this an example of a prezygotic or postzygotic isolating mechanism, by writing pre or post. - -pre Blue-footed boobies (a species of bird) select mates after an elaborate courtship display. They will not mate with other boobies. - -behavioral isolation What is the name for the independent evolution of similar features in species of different lineages that are usually due to living in similar environments? What is this called? - -convergent evolution 7 characteristics of life - -1. cells 2. ordered complexity 3. sensitivity or response to stimuli 4. growth, development, and reproduction 5. energy utilization 6. homeostasis 7. evolutionary life is _____ - -an emergent property deductive reasoning: - -uses general principles to make scientific predictions general----- specific inductive reasoning: - -uses specific observations to develop general conclusions specific----- general step 1 of scientific method - -observation step 2 of scientific method - -2. hypothesis making step 3 of scientific method - -
