They ate fruits, nuts, roots, seeds, and mushrooms they gathered. Occasionally, they ate the meat of small animals they hunted or trapped. Sometimes they dined on the carcass of larger animals killed by a lion, leopard, or tiger, from which they would scavenge some meat and bones. The broken animal bones found at early human sites indicate that early humans especially sought the marrow found inside bones. Its fatty tissue served as a rich source of energy. We do not know when humans first controlled fire, but it was probably more than a million years ago.

Are there advantages to eating food that was produced locally? FOODS Energy is stored in the molecules of the food we eat. In our cells, the molecules react with oxygen, which is carried from our lungs to all the cells of our body by our blood. The reaction between these food molecules and oxygen is not a simple one, such as that in burning wood. It is, in fact, a series of reactions, each of which provides some energy. There are three types of food that can provide the body with energy. They are carbohydrates, fats, and proteins.

Use a paper clip to hold a small folded piece of black construction paper or aluminum foil over both sides of a geranium leaf still on the plant, as shown in Figure 2. Be careful not to damage the leaf when you attach the paper or foil. Do this in the morning on a bright sunny day when lots of light will fall on the leaves.

After four or five hours, pick the leaf from the plant, bring it indoors, and remove the foil or paper.
