8 Researchers are studying a population of robins that has a variety of body masses which is a heritable quantitative factor Graph 1 is a histogram that shows the number of individuals in the population that fall within each range of body masses at the beginning of the study After six summers of higher than usual temperatures and precipitation the distribution has shifted as shown in graph 2 Graph 1 Number of robins 16 Number of robins 14 12 10 4 2 0 Graph 2 16 14 12 10 8 2 0 58 63 58 63 Body Masses of Robins in Year 1 64 69 70 75 76 81 Body mass g 64 69 Body Masses of Robins in Year 7 70 75 Body mass g 76 81 82 87 82 87 88 93 88 93 a How can you use the data to determine which range of masses represents robins that were best adapted to their environment Robins in which range of masses were best adapted to the original environment Robins in which range were best adapted in year 7 3 points b How did natural selection cause a change in the
