100
THE AUTHOR OF ORIGIN OF SPECIES (FIRST AND LAST NAME)
Who is CHARLES DARWIN?
100
THE SCIENTIFIC STUDY OF THE GEOGRAPHIC DISTRIBUTION OF ORGANISMS BASED ON BOTH LIVING SPECIES AND FOSSILS
What is BIOGEOGRAPHY?
100
THIS TYPE OF SELECTION OCCURS WHEN INDIVIDUALS WITH AN EXTREME VARIATION OF A TRAIT ARE FAVOURED.
What is DIRECTIONAL SELECTION?
100
THE EVOLUTION OF A NEW SPECIES OCCURS WHEN MEMBERS OF SIMILAR POPULATIONS CAN NO LONGER _________________________.
What is BREED TO PRODUCE FERTILE OFFSPRING? (the part about fertile offspring is important)
100
BIRD WINGS AND INSECT WINGS ARE AN EXAMPLE OF...
What is ANALOGUS STRUCTURES?
200
HE CONDUCTED DETAILED STUDIES ON FOSSILS; THIS MAN WAS MAD ABOUT BONES
Who is CUVIER?
200
THESE ARE STRUCTURES ARE NON-FUNCTIONING AND ARE HOMOLOGUS TO FUNCTIONING STRUCTURES IN CLOSELY RELATED SPECIES.
What is A VESTIGIAL STRUCTURE?
200
IN ORDER FOR NATURAL SELECTION TO OCCUR, THERE MUST BE ___________ IN TRAITS IN A POPULATION.
What is VARIATION?
200
WHEN TWO POPULATIONS ARE PHYSICALLY SEPERATED FROM ONE ANOTHER, BIOLOGISTS SAY THAT ______ ______ LED TO SPECIATION.
What is GEOGRAPHIC ISOLATION?
200
EXTREMELY LARGE AND EXTREMELY SMALL SPIDERS ARE LESS LIKELY TO SURVIVE. THIS IS AN EXAMPLE OF...
What is STABILIZING SELECTION?
300
THIS MAN POSTULATED THAT SPECIES CHANGE OVER TIME. HE SUGGESTED THAT ORGANISMS WITH SIMILARITIES COULD SHARE A COMMON ANCESTRY.
Who is BUFFON?
300
THESE CHANGES IN DNA OCCUR BY CHANCE, RADIATION OR CHEMICALS.
What is MUTATION? (BONUS: MUTATIONS CAN BE ______, ______ OR _____)
300
THIS TYPE OF SELECTION FAVOURS INDIVIDUALS WITH EITHER EXTREMES OF A TRAIT
What is DISRUPTIVE SELECTION? BONUS: DRAW A FIGURE DEMONSTRATING THIS ON THE WHITE BOARD.
300
THIS TYPE OF EVOLUTION OCCURS WHEN SPECIES THAT WERE ONCE SIMILAR BECOME INCREASINGLY DIFFERENT

400
WHEN INDIVIDUALS ENTER OR LEAVE A POPULATION, THEY TAKE THEIR GENES WITH THEM. THIS IS CALLED _____.
What is GENE FLOW?
400
WHEN ORGANISMS CAN NO LONGER BREED WITH ONE ANOTHER, THEY ARE ________________ ___________ FROM ONE ANOTHER.

What is MIMICRY?
500
THIS MAN SAID THAT A MOTHER COULD "INFLUENCE" TRAITS TO A CHILD
Who is LAMARCK?
500
CHANGES TO AN ALLELE FREQUENCY AS A RESULT OF CHANCE. THESE ARE OBSERVED MORE OFTEN IN SMALL POPULATIONS
What is GENETIC DRIFT?
500
THIS PROCESS DESCRIBES HOW THE ENVIRONMENT FAVOURS INDIVIDUALS WHO POSSES TRAITS THAT ARE ADVANTAGEOUS.
What is NATURAL SELECTION?
500
IF TWO SPECIES ARE PLACED UNDER SIMILAR SELECTIVE PRESSURES, THEY ARE LIKELY TO UNDERGO _______ EVOLUTION.
What is CONVERGENT EVOLUTION?
500
A RARE GENETIC DEFECT THAT CAUSES ABNORMALLY SHORT ARMS AND LEGS IN AMISH POPULATIONS OF THE US IS LIKELY AN EXAMPLE OF...
What is GENETIC DRIFT?
