C. Suitable variations in a population tend to be passed on while unsuitable variations in a population are not. D. Individuals with variations suitable to their environment have shorter lifespans and produce fewer offspring. 5. Which best describes Charles Darwin theory of evolution by natural selection? A. The passing on of genes from one generation to the next B. Change in populations through time because of mutations. C. The development of characteristics by organisms in response to need. D. Change in populations through time as a response to environmental change.

1. When lions prey on a herd of antelope, some antelope are killed and some escape. Which part of Darwin's concept of natural selection might be used to describe this situation? A. acquired characteristics B. common descent C. descent with modification D. survival of the fittest 2. According to Darwin's theory of natural selection, what would best describe the individuals that tend to survive? A. They have the greatest number of offspring. B. They have variations that best suited their environment. C. They possess characteristics that plant and animal breeders' value. D. They possess characteristics from their parents acquired by use and disuse. 3. How did Lamarck explain the development of giraffes' long necks? A. Giraffes just started out with long necks and haven't changed. B. Long-necked giraffes eat more grass than short necked giraffes, so their necks grow longer. C. Some giraffes have acquired longer necks by stretching to reach food and passed that trait on. D. Natural variation in the population produces some longer and some shorter-necked giraffes and longer necked giraffes can reach food more easily.

1. Which best describes Charles Darwin theory of evolution by natural selection? A. The number of offspring is not related to fitness. B. More offspring are produced than can possibly survive. C. The organisms that are the fittest are always largest and strongest. D. Acquired characteristics that are inherited are the cause of evolution. 2. According to Darwin's theory of natural selection, individuals who survive are the ones best adapted for their environment. Which best explains the reason why organisms survived in the changing environment? A. Organisms survived because there is a lack of competition with the species. B. Organisms survived because of the choices made by plant and animal breeders. C. Organisms survived because the possession of adaptations developed through use. D. Organisms survived because of the possession of inherited adaptations that maximize fitness. 3. Which best describes Lamarck's theory of evolution? A. Artificial selection is the basis for evolution. B. Change is the result of survival of the fittest. C. A small population size decreases the rate of evolution. D. Body structures can change according to the actions of the organism. 4 Which is NOT a part of Darwin's theory of natural selection? A. Individuals of a population vary. B. Organisms tend to over-reproduce themselves. C. There are limited resources for which individuals compete. D. Variations possessed by individuals of a population are not heritable. 5. Which best explains why there are differences in traits of organisms according to Lamarck's theory of the evolution? A. It is the result of increases in population size. B. It is the result of an unchanging local environment. C. It is the result of the actions of organisms as they change a body structure. D. It is the result of the natural variations already present within the population of organisms.
