Most stomata are located on the bottom of leaves because direct sunlight does not hit the bottom surface. If stomata were on the upper epidermis (the top side of the leaf), the direct sunlight hitting the leaf would cause more water to be lost through the stomata because of evaporation. Hope this helps!

All DNA is remarkably similar, but some more than others. Humans' DNA would be closer to other mammals' than it is to, say, a bird. Using DNA shows how varied an animal really is from another. Specific parts of the DNA code for different things, so you might see a similar structure for wings and flippers.
