During the late 1970s, environmental change caused flux in the quantities of the different sizes and hardnesses of seeds available to finches in the galápagos. given what you know about natural selection, match each period of environmental change to the average beak depth you would expect to find in the finch populations.

Mars and earth have quite a few things in common. both are  terrestrial planets, both are located within the sun’s  habitable zone, both have  polar ice caps, similarly  tilted axes, and similar  variations in temperature. and according to some of the latest scientific data obtained by rovers and atmospheric probes, it is now known that mars once had a  dense atmosphere  and was covered with  warm, flowing water.
