Remember, we are trying to determine of different groups of individuals are part of the same species or not. - ANSWER Two populations of frogs, where the individuals look like they form two groups by morphology (differing physical characteristics) Take the following sets of objects. Which set exhibits the most variability among individuals? - ANSWER A set of ducks Which statement is most accurate about species formation? - ANSWER A population breaking up into spatially separated groups causes species to form. Which is true about named organismal units with species, such as subspecies? - ANSWER The definition is fuzzy as applied Which mode of speciation is clearly more common in plants than in animals - ANSWER Spontaneous doubling of the chromosome number Natural selection leads to long-term success by organisms which - ANSWER have the most reproductive success BIOL 102 Final Exam Questions and Answers Latest Update (Graded) The process of evolution by natural selection is best characterized as - ANSWER A process with a combination of random and non-random steps, but no predefined endpoint Which is correct about the long-term rate of macroevolution? - ANSWER It varies in speed, sometimes fast and sometimes slow Which observation is NOT important in understanding the evolution of a population? - ANSWER Individuals' appearances change over the course of their lifetimes Neil Shubin, the author of Your Inner Fish, is most interested in which collection of homologous features of vertebrates - ANSWER Limbs (legs, arms, wings) Shubin, in chapter 1, suggests that a walk through the zoo is similar to what? - ANSWER Is laid out in a fashion similar to how fossils are organized in rock layers The fossils discovered by Shubin during his early career in Pennsylvania were contained with in an ancient what? - ANSWER River Delta Tiktaalik, the fossil genus discover by Shubin in the Arctic, was a fossil genus of what? - ANSWER Fish Tiktaalik's, Shubin's arctic fossil, limbs were unusual in that it containded - ANSWER a Wrist Why were Tiktaalik fossils found in the arctic even though the fish was thought to be from tropical locals? - ANSWER Continental drift had caused the fossil deposit to move to higher latitudes Shubin teaches which course at the University of Chicago? - ANSWER Anatomy Features that are similar in organisms that are not evolutionarily related are due to: - ANSWER similar selective pressures DNA is an instruction set containing the "receipe" for bulding what biomolecules? - ANSWER Proteins Why were injections of vitamin A given to shark embryos in Shubins laboratory? - ANSWER Vitamin A was critical in limb development of sharks and other vertebrates.
