Dna Quotes - page 3
Let's instead define life very broadly, simply as a process that can retain its complexity and replicate. What's replicated isn't matter (made of atoms) but information (made of bits) specifying how the atoms are arranged. When a bacterium makes a copy of its DNA, no new atoms are created, but a new set of atoms are arranged in the same pattern as the original, thereby copying the information. In other words, we can think of life as a self-replicating information-processing system whose information (software) determines both its behavior and the blueprints for its hardware.
Max Tegmark
That intermediate manifestation of the divine process which we call the DNA code has spent the last 2 billion years making this planet a Garden of Eden. An intricate web has been woven, a delicate fabric of chemical-electrical-seed-tissue=organism=species. A dancing, joyous harmony of energy transactions is rooted in the 12 inches of topsoil which covers the rock
metal
fire
core of this planet.
Timothy Leary
Let's just grant the possibility that there is a Creator God, who's omniscient, who occasionally authors books. And he's gonna give us a book – the most useful book. He's a loving God, he's a compassionate God, and he's gonna give us a guide to life. He's got a scribe, the scribe's gonna write it down. What's gonna be in that book? I mean just think of how good a book would be if it were authored by an omniscient deity. I mean, there is not a single line in the Bible or the Koran that could not have been authored by a first century person. There is not one reference to anything – there are pages and pages about how to sacrifice animals, and keep slaves, and who to kill and why. There's nothing about electricity, there's nothing about DNA, there's nothing about infectious disease, the principles of infectious disease. There's nothing particularly useful, and there's a lot of iron age barbarism in there, and superstition. This is not a candidate book.
Sam Harris
[wrote_the_exam]What keeps me awake at night: wondering whether human species is just too stupid to figure out the Universe. I just wonder. I lose sleep over that. Because we define ourselves as intelligent- because we made up the test to say that. And we sit alone at the top of the intelligence chart because we invented the exam, and all the other species of life on Earth are not. So who's to say that the first species (us) to be intelligent (us) has just enough intelligence to actually decode everything that's decodable in the Cosmos? [...] Think of the next closest thing to us, the bonobo chimp- 98½% identical DNA, yet you cannot teach them trigonometry, they have no concept of it. So if that's only 1½% difference in our DNA- and so imagine 1½% beyond us, rather than below us, in intelligence. [...] Their toddlers would be talking about things that would completely confound us.
Neil deGrasse Tyson
As someone who's had the privilege of leading the human genome project, I've had the opportunity to study our own DNA instruction book at a level of detail that was never really possible before. It's also now been possible to compare our DNA with that of many other species. The evidence supporting the idea that all living things are descended from a common ancestor is truly overwhelming. I would not necessarily wish that to be so, as a Bible-believing Christian. But it is so. It does not serve faith well to try to deny that.
Francis Collins
I stand at the seashore, alone, and start to think.
There are the rushing waves
mountains of molecules
each stupidly minding its own business
trillions apart
yet forming white surf in unison.Ages on ages
before any eyes could see
year after year
thunderously pounding the shore as now.
For whom, for what?
On a dead planet
with no life to entertain.Never at rest
tortured by energy
wasted prodigiously by the sun
poured into space.
A mite makes the sea roar. Deep in the sea
all molecules repeat
the patterns of one another
till complex new ones are formed.
They make others like themselves
and a new dance starts.Growing in size and complexity
living things
masses of atoms
DNA, protein
dancing a pattern ever more intricate.Out of the cradle
onto dry land
here it is
standing:
atoms with consciousness;
matter with curiosity.Stands at the sea,
wonders at wondering: I
a universe of atoms
an atom in the universe.
Richard Feynman
The entire recent history of biology shows that we are, to a remarkable degree, the results of the interactions of an extremely complex array of molecules; and the aspect of biology that was once considered its holy of holies, the nature of the genetic material, has now been fundamentally understood in terms of the chemistry of its constituent nucleic acids, DNA and RNA, and their operational agents, the proteins.
Carl Sagan
But this (a listing of illustrations of how the genome can change other than by mutations) doesn't constitute a crisis-it's a very interesting finding that shows that variation in a genome can arise by processes other than mutation of an organism's own DNA. The disposition of that variation still must occur via either natural selection (it can be good or bad) or genetic drift (no effect on fitness). This hasn't really changed the theory of evolution one iota, though it's changed our view of where organisms can acquire new genes.
Jerry Coyne
It is a very helpful insight to say we are vehicles for our DNA, we are hosts for DNA parasites which are our genes. Those are insights which help us to understand an aspect of life. But it's emotive to say, that's all there is to it, we might as well give up going to Shakespeare plays and give up listening to music and things, because that's got nothing to do with it. That's an entirely different subject.
Richard Dawkins
