Protein molecules are quite stable; some of them can exist unchanged for hundreds of years and sustain temperatures of hundreds of degrees, which would kill the organism that made them. Proteins are biological macromolecules that are an essential component of organisms and participate in every process within cells. When plants and animals die, microbes break them down; slime molds then devour many of the bacteria, releasing their nutrients for other organisms to grow on. What use would it be knowing the genome sequence of humans and other organisms, for instance, without the technology and expertise needed to exploit this knowledge? Are the organisms actually doing this in Mono Lake, or do they have the latent ability to do so? The ultimate proof of the success of synthetic biology, though, would be not merely an artificial metabolic pathway, but an artificial organism. Biology has a pretty good understanding of how animals develop from a fertilized egg to a fully formed organism. Indeed, there is loose talk of life having originated more than once in the distant past, and of there being entire shadow biospheres of organisms completely unrelated to anything on the surface. The differences which distinguished them as individuals were abstracted by this passion, and each was but portion of one organism called sex. We all share common ancestors, because all life came from the first self- reproducing, single-celled organism that existed in the oceans of primal earth. Bacteria are among the simplest organisms in nature, but many of them can still talk to each other, using a chemical“ language” that is critical to the process of infection. Something like smallpox is hard to get, but there are other organisms that could become harmful. With the possible exception of the propeller-like flagella of bacteria, there are no examples of organisms that use muscles to create continuous rotary motion. A crowd is an organism that grows in its own way and tends to be led and excited by its extremes. They represent more than half of all living organisms on planet Earth. This has been demonstrated in other organisms and could be true in humans as well. These evolutionary theories explain a puzzle: how organisms that sacrifice their own“ reproductive fitness” — their ability to survive and reproduce— could possibly have evolved. Such knowledge has been the basis of a genetic revolution that offers the power to rewrite the material from which all living organisms are made. If entire ecosystems exist embedded in a material such as salt, the discovery also strengthens the possibility that living organisms could be found on other planets. Any interference with homeostasis is likely to be damaging to the organism. Humans, like other organisms, pass certain characteristics of themselves to the next generation through their genes, the special carriers of human traits. The individual feels more than ever dependent on society, but he feels this dependence not in the positive sense — cradled, connected as part of an organic. The apparent veil between the organic and the manufactured has crumpled to reveal that the two really are, and have always been, of one being. |
