BIO 181 - Paciulli NCSU (final exam) Questions and answers, 100% Accurate. VERIFIED. The idea that most speciation is slow and uniform is known as - -gradualism. Darwin's work on the Galapagos Islands led him to derive all of the following concepts, EXCEPT: - -Inheriting acquired characteristics 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 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 Northern elephant seals have reduced genetic variation most likely due to being hunted. Hunting reduced their population size to as few as 20 individuals at the end of the 19th century. Since then, their population has rebounded to over 30,000, but the genes still have much less variation than the genes in a population of Southern elephant seals that were never hunted. This is an example of... - -Bottleneck Effect A phylogeny drawn in the shape of the letter Y represents... - -cladogenesis Sharks and humans excrete the same type of excretory product. This is an example of... - -convergent evolution 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 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... - -Founder Effect Although Jean-Baptiste Lamarck's work was important in the development of evolutionary thought, he was wrong because he believed that characteristics were initially _____. - -acquired A population that is infinitely large and in which mating is completely random is mostly likely to: - -not evolve All of the following EXCEPT which one are mechanisms / modes / forces of evolution? - -Heterozygosity Evolutionary changes within a species are most accurately referred to as: - -microevolution The only source of new genetic variation (material) is / are _____ . - -mutations Which of these would support a population remaining at genetic equilibrium / NOT evolving? (In other words, which of these would not cause a population to evolve?) - -Mating is random The concept that the tempo of evolution is marked by isolated episodes of rapid speciation between long periods of little or no change is known as: - -punctuated equilibrium One way species evolve is by... - -diversification Bart Simpson believed that mice exposed to radiowaves would become extra strong, so he performed an experiment, and placed 11 mice in front of a radio for a day. He compared these 11 mice to another 11 mice that had not been placed by the radio. Bart's test consisted of a heavy block of wood that blocked the mouse food. He found that 8 out of the 11 radio-waved mice were able to push the block away. Seven out of the 11 other mice were able to do the same. Distance from radio; How near / close to the radio the mouse were Number of mice who pushed the block away Mice not exposed to the radio - -independent variable dependent variable control group Match the type of selection to the appropriate description.
