Use at least 1 example from the Beaks of Finches lab in your answer for each.arrow_forwardWhich of the following statements is not true about the concept of natural selection? Group of answer choices A-Geographical isolation contributes to the formation of new species as individuals begin to adapt to different environments B-Natural selection explains the increase in the yield of kernels per corn plant over the last several thousand years C-Infers that later generations may be distinct from ancestral ones, or a new species can appear D-Selective pressures cause distinct species to develop E-Suggests that over long periods of geological time, successful variations accumulate in a populationarrow_forwardThe origin of species by natural selection given by charles darwin was first published in which year?arrow_forward
- How might artificial selection and natural selection produce the same result? Which process would be faster? Why?arrow_forwardOne of the lines of evidence that led Darwin to the theory of natural selection was his study of artificial selection. Plant breeders and pigeon breeders select offspring with specific traits in mind beforehand. a) However, since humans are an integral part of the natural world, do you think that artificial selection might be more appropriately termed “natural selection”? Why?arrow_forwardDefine natural selection? Who else along with Charles Darwin proposed it as the mechanism of evolution?arrow_forward
- Which of the following is true about natural selection? a) It always results in the evolution of new traits b) It always results in the strongest individuals surviving c) It always results in the fittest individuals reproducing d) It always results in the best-adapted individuals survivingarrow_forwardIs natural selection only a negative process that removes nonadapted and lesser adapted forms? Explain your answer.arrow_forwardIf natural selection can only operate on existing variants, where does all that variation come from? If, as Darwin (1868) and Huxley concluded, variation arose from changes in development, then how could the development of an embryo change when development is so finely tuned and complex?arrow_forward
- How does natural selection act on humans in this technological age?arrow_forwardWhat was missing in Darwin’s explanation of evolution by natural selection? How does the modern synthesis fill this gap?arrow_forwardWhile the French biologist LaMarck was correct in proposing that evolution does occur, he believed that the long necks of giraffes evolved as generations of giraffes reached for ever higher leaves on the trees. Using these observations, LaMarck proposed the theory that evolution occurs due to the inheritance of characteristics acquired during an organism’s lifetime. From what you know about the scientific method, why is this incorrect?arrow_forward
