carry cells fusion kinds linking nature organisms sources stores time
We carry stores of DNA in our nuclei that may have come in, at one time or another, from the fusion of ancestral cells and the linking of ancestral organisms in symbiosis. Our genomes are catalogues of instructions from all kinds of sources in nature, filed for all kinds of contingencies.
cells diversity earth
The uniformity of the earth's life, more astonishing than its diversity, is accountable by the high probability that we derived, originally, from some single cell, fertilized in a bolt of lightning as the earth cooled.
cells shining mitochondria
We are not made up, as we had always supposed, of successively enriched packets of our own parts. We are shared, rented, occupied. At the interior of our cells, driving them, providing the oxidative energy that sends us out for the improvement of each shining day, are the mitochondria, and in a strict sense they are not ours.
pain cells agony
There's really no such thing as the agony of dying. I'm quite sure that pain is shut off at the moment of death. You see, something happens when the body knows it's about to go. Peptide hormones are released by cells in the hypothalamus and pituitary gland. Endorphins. They attach themselves to the cells responsible for feeling pain.
opportunity self cells
Given the opportunity, under the right conditions, two cells from wildly different sources, a yeast cell, say, and a chicken erythrocyte, will touch, fuse, and the two nuclei will then fuse as well, and the new hybrid cell will now divide into monstrous progeny. Naked cells, lacking self-respect, do not seem to have any sense of self.
cells resemblance-is whales
It is from the progeny of this parent cell that we all take our looks; we still share genes around, and the resemblance of the enzymes of grasses to those of whales is in fact a family resemblance.
animal cells essentials
Ants are more like the parts of an animal than entities on their own. They are mobile cells, circulating through a dense connective tissue of other ants in a matrix of twigs. The circuits are so intimately interwoven that the anthill meets all the essential criteria of an organism.
science cells atoms
We do not understand much of anything, from... the "big bang" , all the way down to the particles in the atoms of a bacterial cell. We have a wilderness of mystery to make our way through in the centuries ahead.
odds cells people
I agree that you might clone some people who would look amazingly like their parental cell donors, but the odds are that they'd be almost as different as you or me, and certainly more different than any of today's identical twins.
dna cells earth
All of today's DNA, strung through all the cells of the earth, is simply an extension and elaboration of [the] first molecule.
night thinking cells
I have been trying to think of the earth as a kind of organism, but it is no go. I cannot think of it this way. It is too big, too complex, with too many working parts lacking visible connections. The other night, driving through a hilly, wooded part of southern New England, I wondered about this. If not like an organism, what is it like, what is it most like? Then, satisfactorily for that moment, it came to me: it is most like a single cell
blowing waves wind
The waves were big and the wind was blowing hard.
affection close genes guess nature splendid
We are a spectacular, splendid manifestation of life. We have language. . . . We have affection. We have genes for usefulness, and usefulness is about as close to a "common goal" of nature as I can guess at.
base feeding human knack mistakes provided root structure useful
Mistakes are at the very base of human thought feeding the structure like root nodules. If we were not provided with the knack of being wrong, we could never get anything useful done.
