who is Charles darwin

• starbucks owner
• a bird
• a christian
• a naturalist

what gave Charles Darwin the idea of evolution?

• google
• wikipedia
• mans attempt to destroy mankind
• finches in the Galapagos island

Which statement best describes the process of evolution?

• Populations can survive in different locations on earth
• Environmental conditions limit the number of species on Earth
• Populations grow when resources are abundant
• The traits of a species can change over time

Which of the following ideas is supported by Darwin’s observation of local variation among tortoises in the Galápagos Islands? 

• artificial selection
• adaptation
• acquired characteristics
• tendency towards perfection

Charles Darwin’s observation that finches of different species on the Galápagos Islands have many similar physical characteristics supports the hypothesis that these finches 
 

• have the ability to interbreed.
  have the ability to interbreed.
• acquired traits through use and disuse.
• all eat the same type of food.
• descended from a common ancestor.

According to Darwin’s theory of natural selection, individuals who survive are the ones best adapted for their environment. Their survival is due to the 

• possession of adaptations developed through use.
•  possession of inherited adaptations that maximize fitness.
• lack of competition within the species.
• choices made by plant and animal breeders.

Each of the following is a condition necessary for natural selection to occur EXCEPT 

• more offspring are born than can survive.
•  population size is very large. 
• fitness varies among individuals.
• there is heritable variation among members of the population.

Which statement is part of Darwin’s theory of evolution by natural selection? 

• More offspring are produced than can possibly survive.
• The organisms that are the fittest are always largest and strongest. 
• The number of offspring is not related to fitness.
• Acquired characteristics that are inherited are the cause of evolution.

Charles Darwin’s theory of evolution by natural selection explains each of the following EXCEPT how 

• species can become extinct.
• inherited traits are passed from parent to offspring
• species descend from common ancestors. 
• evolution takes place in the natural world.

What were Darwin's 4 major finding about evolution?

• Millions of species alive today arose from single original

  life form branching through a process known as speciation

• Evolutionary change was gradual

• Evolution is process that moves towards complexity and perfection

• Evolution did occur

• The primary mechanism for evolution is natural selection
