• Q Give a definition of evolution.
• A Change of a species over time (usually
  gradual)

• Q Why are mutations and random combinations of
  parental genes so important to evolution?
• A Variation.provides template for change to
  occur

• Q If a portion of a deer population is cut off
  from its parent population by a large mountain
  range for over a 1000 years, describe what the
  end result could be?
• A Speciation

5

• Q A gene mutation takes place in the nerve
  cells of a chimpanzee. Will this trait be passed
  on to its offspring? Why?
• A No! Mutation must take place in sex cells.

• Q Why is Lamarck important regarding
  evolutionary theory?
• A He coined the phrase adaptation.

• Q Why was Lamarck wrong in regards to his
  theory of evolutionwhat example did he use?
• A Theory of Use and Disuse..giraffes.

• Q What is natural selection?
• A Those individuals of a species who are best
  adapted (through inherited traits) to an
  environment will most likely survive.

• Q How can an asexually reproducing species
  evolve?
• A Mutation

• Q Which type of organisms did all life forms
  most likely evolve from?

• Q Why were the Galapagos so important to
  Darwins theory of evolution?
• A Different species of finch with different
  beak size and shapes, adapted to environment
  (food source) of each island.

14

• Q The bone structure of modern humans is very
  similar to the bone structure of Neanderthals, an
  extinct hominid species. What does this evidence
  suggest?
• A Common ancestor

• Q How would you describe the scenario of a
  horse breeder who mates certain horses to pass
  along favorable traits?
• A Artificial Selection

16

  in a snake species?
• A Vestigial structures

• Q What is troublesome about the cheetah gene
  pool?
• A There are few differences in inheritable
  genes for the population, cannot change.

18

• Q Why can the path of evolution be represented
  by a bush, rather than a straight line?
• A Species are always branching out randomly,
  many have gone extinct, while others have
  survived to present day.

• Q Why might polar bears be extinct within the
  next 100 years?
• A They are very specialized to a cold climate,
  they may not be able to adapt to a warming planet.

  female mouse giving birth to a litter of 10
  young, all with slightly different
  characteristics?
• A Overpopulation and Variation

• Q Why is the term Survival of the Fittest
  somewhat misleading?
• A It is not always the strongest (physically)
  organism that is best adapted to an environment
  (think mammals and dinosaurs).

  in the arm/hand of a human and the wing of a bat,
  what does this evidence support?
