Solution:
Note that according to the table, the rainfall increased each year, which will endanger organisms that are above ground and cannot climb. Now, because the longer-legged lizards can climb to reach high food sources and escape from the ground when floods or storms occur, then these members of the population have better characteristics, depending on the environment they are adapted to (lots of rain ). Therefore, according to natural selection, these lizards will probably have a higher survival rate and therefore will be more likely to prevail and their genes to be inherited from generation to generation.
