Q.1
Genetic drift is change in the allele frequency of a population due to...
  • random chance
  • natural selection
  • non-random mating (sexual selection)
  • artificial selection
Q.2
What is speciation?
  • combining of two species to form one with different traits
  • Intentional breeding designed to maintain a desired trait
  • timing of mating that prevents normal sexual selection
  • A population splits and accumulates different genes in the new groups
Q.3
A phenotype that improves an organism’s chance of survival in their environment is considered a(n) ____________.
  • natural selection
  • adaption
  • speciation
  • All of above
Q.4
Individuals undergo evolution.
  • True
  • False
Q.5
Over generations of time apart on different islands with different food sources, the separated populations of Galapagos finches accumulated genetic differences until each group had different beaks. This is an example of _____.
  • natural selection
  • genetic drift
  • adaptation
  • speciation
Q.6
Brown mice survive and reproduce in their desert environment better than white mice because owls can see and eat the white mice more easily. In this situation, what part of the environment is doing the selecting?
  • predator
  • soil composition
  • mouse fur color
  • sexual preferences
Q.7
Natural selection results in change in a population's _____________ traits over time.
  • inherited
  • acquired
Q.8
This makes an organism more suited to its enviornment
  • species
  • lifespan
  • adaptation
  • mutation
Q.9
What would indicate that a series of fossils represent evolution?
  • the fossils were identical
  • the fossils were found in the same layers of rock
  • the fossils show similarities
  • the fossils were completely different
Q.10
Why do embryologist study embryos?
  • to see if they are related
  • to understand adaptations
  • to determine the age
  • to learn what parents are vestigial
Q.11
What is embryology?
  • the age of organisms
  • the oldest stage of development
  • the life span of an organism
  • the earliest growth stage of development
Q.12
Change over time is
  • evolution
  • generation
  • growth
  • biogenesis
Q.13
Natural selection is
  • survival of the fittest
  • humans change
  • two species are the same
  • more animals survive
Q.14
Which of the following is not a piece of evidence for evolution?
  • Homologous structures
  • embryology
  • fossil age
  • vestigial structures
Q.15
Surviving and reproducing show that an organism
  • is adapting
  • is not adapting
  • is forming fossils
  • is not reproducing
Q.16
What is one reason that strawberries are surviving in the winter season?
  • they have larger leaves
  • they have genetic variations allowing them to be resistant to cold
  • they reproduce more
  • the color is dark
Q.17
Genetic diversity
  • allows for a small population
  • allows for similar physical features
  • allows for genetic diversity
  • allows for low mutation rates
Q.18
The tree of life is a metaphor for what idea?
  • we came from a common ancestor
  • we need water and sunlight to survive
  • we have multiple species
  • we are old
Q.19
Who was Charles Darwin?
  • A naturalist who came up with the theory of evolution
  • A scientist who studied plants
  • A geologist who looked at rocks and fossils
  • A paleontologist who studied dinosaurs
Q.20
What animal is Darwin known for studying?
  • dinosaurs
