- Why do we need to be careful when we make assumptions about grave goods and what they might mean? A. Because there are always written histories about artifacts and archaeologists should read them. B. Because the assumptions that we might make about grave goods in our modern society may not match the actual purpose of that object in a prehistoric society. C. None of these are correct. D. Because archaeologists are never able to make any conclusions about artifacts if there is no written history.arrow_forwardWhich statement illustrates the connection between natural selection and overreproduction of a population? a) populations vary in their inherited traits. b) species produce more offspring than can survive in the environment. c) individuals with inherited traits that promote survival tend to have more surviving offspring. d) individuals with traits that do not enhance survival cannot reproduce.arrow_forwardDog breeders use selective breeding, also called artificial selection, to maintain a closed genetic lineage, and produce offspring with desirable traits. This violates which Hardy-Weinberg condition? a reproduction b no mutation c random mating d no natural selectionarrow_forward
