. . . .Photosynthesis first evolved about 2.4 billion years ago, so long ago that everything living on Earth still had only one cell and lived in the water. Those first photosynthetic organism therefore weren’t plants as we know them today but sing celled algae, like those that make up the mat you might see on the surface of a polluted pond, for example. Many kinds of single celled algae are still around today, but one lineage of algae has changed a lot since then, becoming multicullular adapting to life on land, and becoming the plants we know and love (IN other words, plants are specialized kinds of algae.) ~ Page 101

. . . .As adaptationism took hold, such explanations came to seem irrelevant. It became a rich and fruitful problem to explain a leaf in terms of how natural selection shaped such an effective solar panel. Only much later did some scientists start to puzzle again over the side of nature left unexplained. Leaves come in just a few shapes, of all the shapes imaginable; and the shape of a leaf is not dictated by its function. ~ Page 202
