Scientific Method
What is the scientific method?
What is: A systematic way to investigate phenomena/science questions.
What term best describes "survival of the fittest traits"?
What is: Natural selection
What is the name for all the fossils and their information, including all physical changes of organisms over long periods of time
What is: Fossil record
What is it called when an organism has a preference for certain traits in mates?
What is: Sexual selection.
What type of isolation occurs due to physical separation?
What is: geographic or allopatric isolation.
Which process of the scientific method does "a testable prediction" best describe?
What is: Hypothesis
What term means to have the ability to survive and reproduce?
What is: Fitness
List the types of evidence for evolution.
Fossils, DNA, Anatomy, Embryology, Biogeography, Direct Observation
What is it called when there are random changes in allele frequencies?
What is: Genetic drift
What type of isolation occurs due to barriers that prevent interbreeding?
What is: Reproductive isolation.
What term best describes the variable that is changed in an experiment?
What is: The Independent Variable
What do we call an environmental factor(s) that affects survival?
What is: Selective pressure
What is a gene pool?
What is: All of the different combinations of genes (parts of DNA) in a population.
Describe the bottleneck effect.
What is: Population size reduction leading to genetic loss.
What type of isolation occurs due to species breeding at different times?
What is: Temporal isolation.
What do we call the unchanged or untreated variables in an experiment?
What is: Control group or controlled variables
Describe adaptations.
What is: Traits that improve survival.
What is embryology?
What is: Study of embryo development for evolutionary evidence.
What is the founder effect?
What is: Small group of individuals start a new population
What type of isolation occurs due to differences in mating behaviors?
What is: Behavioral isolation
True or False: Scientists only perform experiments ONCE regardless if the data matches their hypothesis.
What is: False
What are the characteristics of life?
What is: Homeostasis, metabolism, having cells, reproduction, growth and development, and responding to the environment.
What is the difference between homologous and analogous structures?
What is: Homologous structures: similar structures, not always the same function; Analogous structures: similar function, but not from same common ancestor
Explain the morphological species concept.
What type of speciation occurs when there are no physical barriers?
What is: Sympatric speciation
