Biological Evolution - CORRECTANSWER organisms change over time
Darwin - CORRECTANSWER Theory of Natural Selection (short necked giraffes die and therefore,
don't reproduce)
Lamarck - CORRECTANSWER Inheritance of Acquired Characteristics (giraffes stretch their necks
to reach food and then their offspring are born with the longer neck)
Evidence of Evolution - CORRECTANSWER Fossils, Transitional Forms, Analogous Structures,
Homologous Structures, Vestigial Structures
Fossils - CORRECTANSWER hard body parts, embedded in sedimentary rock, deposited in Strata
,Mold - CORRECTANSWER air space remains
Cast - CORRECTANSWER Silica fills space
Transitional Form - CORRECTANSWER Whale: reduced hind limbs and pelvic bones
Analogous Structure - CORRECTANSWER evolved separately but have similar functions ex.
human and octopi eyes
Homologous Structure - CORRECTANSWER similar structure but have different functions ex.
arm, cat, whale, bat
biochemical evidence of evolution - CORRECTANSWER DNA, ATP, enzymes are universal
Genetic Code evidence of evolution - CORRECTANSWER RNA to amino acid triplets are
universal, many genes are shared by all organisms
Microevolution - CORRECTANSWER change in allele frequency in a population over time
who evolves - CORRECTANSWER populations
Hardy Weinberg Equilibrium - CORRECTANSWER No mutations, No genetic drift, No gene flow,
No natural selection, Random Mating
Mutation - CORRECTANSWER cause allele frequency in a populations, only source of variation,
random events
, Genetic Drift - CORRECTANSWER causes allele frequency to fluctuate; greater in smaller
populations
Bottleneck Effect - CORRECTANSWER catastrophe kills large amount of people, loss of genetic
diversity; recessive alleles become more present
Gene Flow - CORRECTANSWER movement of alleles between populations; mixes genetic
diversity in a populations; makes two pools or more similar populations similar
Random Mating - CORRECTANSWER individuals do not choose mates, never observed in natural
population
Natural Selection - CORRECTANSWER heritable variation, over-reproduction causes competition
and differ in reproductive success and fitness, Adaptation
Natural Selection: Stabilizing Selection - CORRECTANSWER select against extremes
Natural Selection: Directional selection - CORRECTANSWER one extreme is favored
Natural Selection: Disruptive Selection - CORRECTANSWER both extremes favored
Macroevolution - CORRECTANSWER speciation and divergence of life
Speciation - CORRECTANSWER group of organisms capable of interbreeding
Habitat Isolation - CORRECTANSWER Pre zygotic; Same environment, different niche
