THIS INDIVUDAL LAID OUT OUR MODERN DAY DEFINITION OF EVOLUTION
WHO IS CHARLES DARWIN
A CHANGE IN ALLELE FREQUENCIES OVER TIME (GENERATIONS)
WHAT IS... EVOLUTION
A GROUP OF INDIVIDUALS OF THE SAME SPECIES THAT LIVE IN THE SAME AREA & INTERBREED ARE KNOWN AS
WHAT IS... POPULATION
SIMILARITIES IN THE BODY PARTS OF ORGANISMS DUE TO A COMMON ANCESTOR
SIMILARITIES IN THE BODY PARTS OF ORGANISMS NOT DUE TO A COMMON ANCESTOR
WHAT IS.... HOMOLOGOUS ---- ANALOGOUS
WHEN THE HETEROZYGOUS GENOTYPE HAS A HIGHER FITNESS THAN EITHER HOMOZYGOUS DOMINANT OR RECESSIVE
WHAT IS... HETEROZYGOTE ADVANTAGE
CHARLES DARWIN'S DEFINTION OF EVOLUTION - WHERE SPECIES DECEND FROM AN ANCESTRAL SPECIES BUT ARE MODIFIED OVER TIME AND SPACE
WHAT IS... DESCENT WITH MODIFICATION
ORGANISMS WITH CERTAIN HERITABLE TRAITS ARE BETTER ABLE TO SURVIVE AND REPRODUCE THAN THOSE WHO DO NOT HAVE THOSE TRAITS
WHAT IS... NATURAL SELECTION
ALL OF THE GENES IN A POPULATION
WHAT IS... GENE POOL
THE INDEPENDENT EVOLUTION OF SIMILAR FEATURES NOT DUE TO A COMMON ANCESTOR BUT SIMILAR ENVIRONMENT IS
WHAT IS... CONVERGENT EVOLUTION
THIS TYPE OF REPRODUCTIVE ISOLATION OCCURS BEFORE MATING OR FERTILIZATION
WHAT IS... PRE-ZYGOTIC BARRIER
THIS IS THE THEORY THAT INDIVIDUALS WITH MODIFIED TRAITS PASS THEM ONTO THEIR OFFSPRING - CAUSING EVOLUTION THROUGH AQURIED TRAITS
WHAT IS THE... THEORY OF AQURIED CHARACTERISTICS
AN ABIOTIC OR BIOTIC FACTOR IN AN ENVIRONMENT THAT ACTS ON A POPULATION - TEMPERATURE, COMPETITION, DISEASE, NUTRIENTS, SHELTER
WHAT IS... SELEVTIVE PRESSURES
CHANCE EVENTS THAT CAUSE ALLELE FREQUENCIES TO CHANGE.
(+100 - FOR IDENTIFYING EACH TYPE)
WHAT IS... GENETIC DRIFT (FOUNDERS EFFECT & BOTTLENECK)
DIVERSITIFICATION OF ORGANISMS FROM ANCESTRAL SPECIES - RESULT OF ENVIRONMENTAL CHANGES, NEW RESOURCES AVAILABLE, NEW NICHES
WHAT IS... ADAPTIVE RADIATION
ARE FOUND AT THE TIPS OF A CLADOGRAM
ARE THE COMMON ANCESTORS OF ALL TAXA DOWNSTREAM OF THE NODE
1. WHAT IS TAXA
2. WHAT IS NODES
HUMANS SELECTING FOR CERTAIN TRAITS AND BREEDING THEM
WHAT IS... ARTIFICAL SELECTION
WHAT IS... ADAPTIONS
TRANSFER OF GENES INTO OR OUT OF A POPULATION
WHAT IS... GENE FLOW
OCCURS WHEN A GROUP WITHIN A SPECIES SEPERATES AND DEVELOPS ITS OWN UNIQUE CHARACTERISTICS
WHAT IS... SPECIATION
THIS SPECIES CONCEPT IS LIMITED BY THE FACT IT CANNOT BE APPLIED TO ASEXUAL ORGANISMS, FOSSILS, AND ORGANISMS WE KNOW LITTLE ABOUT
WHAT IS... BIOLOGICAL SPECIES CONCEPT
THIS TYPE OF SELECTION SELECTS FOR ONE EXTREME
THIS TYPE OF SELECTION SELECTS FOR THE INTERMEDIATE
THIS TYPE OF SELECTION SELECTS FOR BOTH EXTREMES
1. DIRECTIONAL
2. STABILIZING
3. DISRUPTIVE
A CHANGE IN THE INHERITED CHARACTERISTICS OF POPULATIONS OVER SUCCESSIVE GENERATIONS
WHAT IS... EVOLUTION
SEXES OF SOME SPECIES EXHIBIT THIS... MALES AND FEMALE HAVE DIFFERENT SECONDARY SEXUAL CHARACTERISTICS (SIZE, WEIGHT, COLOR, MARKINGS)
SEXUAL DIMORPHISM
1. CHANGE IN ALLELE FREQUENCIES WITHIN A SINGLE SPECIES OR POPULATION
2. LARGE EVOLUTIONARY PATTERNS
2. WHAT IS... MACROEVOLUTION
ON WHAT TAYLOR SWIFT ALBUM IS THE SONG - CRUEL SUMMER
WHAT IS... LOVER ALBUM
