Evolution Exam 1 UPDATED Exam
Questions and CORRECT Answers
Darwin - Correct Answer- discovered natural selection, "tree of life", went to Galapagos
islands and saw population adaptation
Carolus Linneas - Correct Answer- founder of modern taxonomy; he was anti-evolution
Nicolaus Steno - Correct Answer- developed ideas on geology and stratigraphy; realized there
must have been some sort of historic change
•William Smith - Correct Answer- Used distinct groups of fossils; produced first geological
map
•Jean Baptiste-Lamarck - Correct Answer- Proposed that species evolve through natural
processes; Claimed that adaptation occurred through inheritance of acquired changes;
everything comes from microbes
voyage of the beagle - Correct Answer- Realized that the earth is older than he thought;
Studied geology and read The Principles of Geology by Lyell
Uniformitarianism - Correct Answer- observable natural processes today were responsible for
events in the past
Great Chain of Being - Correct Answer- ranked life on a scale; was the dominant view of
biodiversity for two millennia
Georges Buffon - Correct Answer- pre-Darwin; Earth formed according to laws of physics
and chemistry; Earth was older than previously thought (calculated to be at least 70,000 years
old); Life emerged as distinct types; transformed when environment changed
Mary Anning - Correct Answer- discovered several species of extinct marine reptiles
, James Hutton - Correct Answer- believed that earth was old b/c of rock formations;
observable processes produce small changes that accumulate over vast amounts of time
proof of Darwin's "evolution" - Correct Answer- differences of Galapagos finch beaks, fossils
of animals that were similar-but not identical- to animals today
Descent with Modification - Correct Answer- all species share common ancestry and changes
occur through natural selection
Homologous traits - Correct Answer- similar because of inheritance from a common ancestor
Adaptation - Correct Answer- traits that have evolved by natural selection
Darwin's Earth age conclusion - Correct Answer- earth took 300 million years to form
Lord Kelvin - Correct Answer- argued that earth was no more than 20 million years old, later
he was proved to be wrong
Unstable isotopes (radioisotopes - Correct Answer- have fixed probabilities of decaying, or
transforming into a more stable form
Radioisotopes - Correct Answer- •can be used as "clocks" to provide absolute dates of rocks
Isotopes - Correct Answer- •Isotopes with high decay probabilities decay more quickly;
isotopes with low decay probabilities decay more slowly
Examples of fossils explaining behavior - Correct Answer- A. Mating behavior in turtles
B. Live birth of ichthyosaurs
C .Feeding behavior of fish
CT scans - Correct Answer- helped determine function of hadrosaur crest
•Crest connected to nasal cavity
