100
NATURAL SELECTION STATES THAT ORGANISMS WITH CERTAIN HERTIABLE TRAITS ARE BETTER ABLE TO _________ & __________
WHAT IS.... SURVIVE & REPRODUCE
100
IN SOME CASES A MUTATION (ADAPTION) IS SO BENEFICAL IT APPEARS IN ALL INDIVIDUALS IN A POPULATION. WE WOULD THEN SAY THE ALLELE IS
WHAT IS... FIXED
100
ROCK LAYERS AT THE BOTTOM USUALLY DISPLAY WHAT
OLDER, MORE SIMPLE ANCESTRAL SPECIES
100
THIS TYPE OF SPECIATION IS SLOW, UNIFORM, AND GRADUAL
WHAT IS... GRADUALISM
100
DURING HARDY-WEINBERG, IF THERE ARE NO DIFFERENCES IN ALLELE FREQUENIES BETWEEN POPULATIONS THEN
WHAT IS... THE POPULATION IS NOT EVOLVING
200
EVOLUTION OCCURS WITHIN A __________ AND OVER THE COURSE OF MANY ___________.
WHAT IS... POPULATION & GENERATIONS
200
THE ONLY WAY TO HAVE CAUSE NEW VARIATION IN A POPULATION IS
WHAT IS... MUTATIONS
200
A SCIENTIST LOOKING AT SIMILARITIES IN ADULT SPECIES IS
A SCIENTIST LOOKING AT SIMILARITIES IN EMBROYNIC SPECIES IS
TRAITS FROM A COMMON ANCESTOR THAT NO LONGER SERVE A PURPOSE ARE
COMARPTIVE MORPHOLOGY
COMARPITIVE EMBRYOLOGY
VESTIGIAL STRUCTURES
200
THIS SPECIES CONCEPT DEFINES A SPECIES BASED ON - IF THE SPECIES LOOK SIMILAR TO EACH OTHER & DIFFERENT FROM OTHERS
THIS SPECIES CONCEPT DEFINES A SPECIES BASED ON - IF THE SPECIES IS ADAPTED TO USE A SPECIFIC RESOURCE (NICHE)
WHAT IS...
PHENETIC
ECOLOGICAL
200
LIST ALL OF THE ORGANISM WHO HAVE AMNIOTIC EGGS
REPTILES, BIRDS, RODENTS, PRIMATES
300
IDENTIFY ONE OF THE MAIN POINTS OF DARWIN'S THEORY OF EVOLUTION
1. SPECIES CHANGE OVER TIME & SPACE -- OFFSPRING DIFFER FROM ANCESTORS
2. ALL ORGANISM SHARE A COMMON ANCESTOR
3. EVOLUTION IS LOW & GRADUAL
300
In a bird population, there is variation in beak size. One year, it was found that medium-sized bill birds were most common. Next year during a drought, most of the population died off. The birds with large-sized bills were able to survive and reproduce easiest. What type of selection is displayed before the drought? What type is displayed after?
WHAT IS... STABILIZING -- DIRECTIONAL SELECTION
300
WHAT TYPE OF EVIDENCE FOR EVOLUTION IS DESCRIBED... YOU ARE WATCHING AS THE FREQUENCY OF ANTIBIOITC BACTERIA ARE INCREASING - DUE TO SURVIVAL AND REPRODUCTION - AFTER THE INITAL APPLICATION OF AN ANTIBIOTIC
WHAT IS... DIRECT OBSERVATION
300
WHAT MUST OCCUR IN ORDER FOR SPECITATION TO OCCURS
WHAT IS... REPRODUCTIVE ISOLATION AND RESTRICTED GENE FLOW
300
NAME ALL 5 CONDITIONS THAT MUST BE MET FOR A SPECIES TO BE IN HARDY-WEINBERG
1. NO GENE FLOW
2. NO NATURAL SELECTION
3. RANDOM MATING (NO SEXUAL SELECTION)
4. NO MUTATION
5. LARGE POPULATION SIZE
400
NAME THREE MECHAISMS OF EVOLUTION
1. GENETIC DRIFT
2. GENE FLOW (MIGRATION)
3. NATURAL SELECTION
4. SEXUAL SELECTION
5. MUTATIONS
400
WHY DOES SEXUAL SELECTION CREATE POTENTIALLY HARMFUL & EXTREME SECONDARY SEXUAL CHARACTERISTICS
THESE CHARACTERITICS SYMBOL "GOOD GENES" - AS THEY ARE ABLE TO HAVE THE GENES AND STILL SURVIVE/REPRODUCE
400
CONVERGENT EVOLUTION IS TO ________ STRUCTURES, AS DIVERGENT EVOLUTION IS TO ________ STRUCTURES
WHAT IS ANALOGOUS... HOMOLOGOUS
400
A RIVER FORMS OVER THE COURSE OF 10,000 YEARS SLOWLY ISOLATING ONE PORTION OF A POPULATION FROM ANOTHER. AS A RESULT, WHEN THE TWO MEET EACHOTHER LATER, NEITHER VIEWS THE OTHER AS A VIABLE MATE. WHAT TYPE OF SPECIATION IS THIS?
WHAT IS... ALLOPATRIC
400
IN THE PICTURE WHO IS THE MOST RECENT COMMON ANCESTOR OF NON-AVIAN DINOSAURS AND BIRDS
WHAT IS... DINOSAURIA
500
LIST THE 4 CONDITIONS OF NATURAL SELECTION
1. VARIATION
2. INHERITENCE
3. OVER-REPRODUCTION
4. DIFFERENTIAL SURVIVAL & REPRODUCTION
500
IN THE 1900S, THE BEARDED VULTURE POPULATION WAS ALMOST HUNTED TO EXTINCTION BY HUMANS. THEIR NUMBERS WERE SO REDUCED AT ONE POINT, THERE WERE NO WILD "BONE CRUSHER" VULTURES. AS A RESULT, THEIR GENETIC DIVERSITY WAS AFFECTED, AS MANY ALLELES WERE REMOVED FROM THE POPULATION. THIS IS AN EXAMPLE OF:
WHAT IS... BOTTLENECK EFFECT
500
WHY DO SPECIES WITH SIMILAR ANCESTRAL POPULATIONS DISPLAY SLIGHTLY DIFFERENT VARIATIONS IN MORPHOLOGICAL TRAITS.
DIFFERENT ENVIRONMENTS SELECT FOR CERTAIN TRAITS DIFFERENTLY
500
IDENTIFY A MECHANSIM OF MICROEVOLUTION
IDENTIFY A MECHANISM OF MACROEVOLUTION
1. NATURAL SELECTION, SEXUAL SELECTION, GENE FLOW, GENETIC DRIFT, MUTATIONS
2. ADAPTIVE RADIATION, MASS EXTINCTION

WHAT IS AN EXAMPLE OF SISTER TAXA IN THE CLADOGRAM ABOVE
NON-AVIAN DINOSAURS & BIRDS
RESTUDINES & LEPIDOSAURIA
