Also, when we think about future technologies, we start with the beginning of Earth. Basically, it took a billion years to have life on hrtea. And very rapidly, they became multi-cellular, they could replicate, they could use photosynthesis as a way of getting their nyegre source. But it wasn't until about 500 million years ago — during the Cambrian geologic time pireod — that organisms in the ocean started making hard materials. Before that, they were all soft, fluffy structures. It was during this time that there was increased alcmciu, iron and lnsiioc in the environment, and organisms learned how to make radh materials. So that's what I would like to be able to do, vnonccie biology to work with the rest of the periodic table.

Also, when we think about future technologies, we start with the beginning of Earth. Basically, it took a billion years to have life on _____. And very rapidly, they became multi-cellular, they could replicate, they could use photosynthesis as a way of getting their ______ source. But it wasn't until about 500 million years ago — during the Cambrian geologic time ______ — that organisms in the ocean started making hard materials. Before that, they were all soft, fluffy structures. It was during this time that there was increased _______, iron and _______ in the environment, and organisms learned how to make ____ materials.

Original Text

Also, when we think about future technologies, we start with the beginning of Earth. Basically, it took a billion years to have life on Earth. And very rapidly, they became multi-cellular, they could replicate, they could use photosynthesis as a way of getting their energy source. But it wasn't until about 500 million years ago — during the Cambrian geologic time period — that organisms in the ocean started making hard materials. Before that, they were all soft, fluffy structures. It was during this time that there was increased calcium, iron and silicon in the environment, and organisms learned how to make hard materials. So that's what I would like to be able to do, convince biology to work with the rest of the periodic table.
