OCCURENCE OF EVOLUTION

Darwin observed the finches on the Galapagos island were similar in form except for variations of their beaks. He deduced that these variations were useful for __________________.

• getting food

• building nests

• attracting a mate

• surviving the cold

Which of the following statements supports the idea that extinction is necessary?

• know who is the fittest

• To give way for other organisms to develop

• To let other organisms evolve and progress

• All of the above

Natural selection results to______________________.

• evolution due to natural selection

• extinction due to natural selection

• extinction due to artificial selection

• evolution due to survival of the fittest

The organisms that survive in this world of competition are described as

• the fittest

• best looking

• best adapted

• the strongest

Which of the following statements about Darwin is true?

• He thought that the biggest and strongest animals are always at an advantage in natural selection

• He failed to convince the majority of biologists and other educated people in the late 19th century that life evolves

• The Origin of Species, his book that did not sell well and did not take much notice from biologists in his time

• None of the above

Which of the following statements is true about Charles Darwin?

• He supported Lamarck's explanation of how evolution occurred.

• He believed that evolution was due to the inheritance of acquired characteristics

• He understood that the variation that exists in natural populations of plants or animals is the result of repeated mutations.

• None of the above

Which of the following statements best explains the Theory of Natural Selection?

• Acquired characteristics of parents can be passed on to offsprings.

• Organisms develop desirable structures to survive in a given environment

• Organs that are not used may disappear, while organs that are constantly used may develop.

• In nature, the organism with desirable characteristics may survive, while those with weaker traits may not

Through careful observation, Charles Darwin came to understand that:

• Populations of plants and animals in nature most often consist of individuals that are clones of each other

• Populations of a species that become isolated from others by adapting to different environmental niches quickly become extinct

• Those individuals whose variation give them an advantage in staying alive long enough to reproduce are more likely to pass their traits on to the next generation

• all of the above

Which of the following statements DOES NOT describe evolution?

• Evolution is continuous.

• Evolution refers to change

• The world is stable and unchanging

• If there is mutation, there is evolution

.Charles Darwin was best known in the 19th century for:

• creating the idea of evolution

• creating the idea of uniformitarianism

• making the idea of evolution acceptable for scientists and general public

• all of the above
