During his voyage on the Beagle, Charles Darwin made many observations
-in England -in N America -in S America -in Asia
-in S America
In the 1800s, Charles Lyell emphasized that
-the human population will outgrow the available food supply -all populations evolve through natural selection -Earth is very young -gradual geological events in the past could explain the physical features of today's Earth.
-gradual geological events in the past could explain the physical features of today's Earth.
WHen a farmer breeds only his or her best livestock, the process involved is
-natural selection -artificial selection -artificial variation -survival of the fittest
-artificial selection
Charles Darwin's observation that finches of different species on the Galapagos Islands have many similar physical characteristics supports the hypothesis that these finch species
-have grown larger since Darwin's visit -acquired traits through use and disuse-all eat the same type of food. -originated from a common ancestor
-originated from a common ancestor
Which of the following statements best describes the findings of Rosemary and Peter Grant's study of the Galapagos finches?
-Finches with large beaks always outcompete finches with small beaks -Small finches reproduce more successfully than large finches -Food availability affected beak size -Beak size among finches did not affect reproductive success
-Food availability affected beak size
The separation of populations by barriers such as rivers, mountains, or bodies of water is called
-Timing isolation -Geographic isolation -Behavioral isolation -Genetic equilibrium
-Geographic isolation
A factor that keeps species separate is
-Reproduction at different times -Incompatible reproductive structures -Different mating behaviors -All of the above
-All of the above
The length of time required for half of the radioactive isotope in a sample to decay is its
-Half-life-Relative date -Radioactive date -Geologic time scale
-Half-life
In the past, mass extinctions encouraged the rapid evolution of surviving species
-By changing developmental genes-By providing new opportunities for them -Because they killed all organisms that had evolved together-Because they spared all organisms that had evolved convergently
-By providing new opportunities for them
One way master control genes, or homeotic genes, could have affected evolution is
-By causing mutations in other genes-Through small changes in timing during embryonic development -Through the evolution of species -By leading to convergent evolution
-Through small changes in timing during embryonic development
Which of these labels for fossils in a museum display contains an error?
-Dinosaur (MIddle Mesozoic) -Early Mammal (Middle Paleozoic) -Early Human (Late Cenozoic) -Early Marine Invertebrate (Early Paleozoic)
-Early Mammal (Middle Paleozoic)
An analysis of derived characters is used to generate a
-fossil record -phylogenetic tree based on DNA structure -cladogram -traditional classification system
-Cladogram
What does a cladistic analysis show about organisms?
-the relative importance of each derived character -The order in which derived characters evolved -the general fitness of the organisms analyzed -All traits of each organism analyzed
-The order in which derived characters evolved
Organisms in the domains Bacteria and Archaea were previously grouped in a kingdom called
-Anamalia -Fungi-Monera -Eukarya
-Monera
Which of the following is not found in bacteria?
-cell wall -membrane-bound nucleus -ribosome -plasma membrane
-membrane-bound nucleus
