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;

Uniformitarianism - Correct Answer- observable natural processes today were responsible for
events in the past

biodiversity for two millennia

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;

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
