Quotes About Reproduction

The important thing to realize is the males in most species will breed with any female who stays still long enough. It's the females who are selective. What they desire has a huge effect. If all the female walruses got together one day to decide they wanted polka dots, within a few generations the males would have polka dots. The female's wish made physical on the male's body.

Reverend Father, your line of thought has taken a dangerous path! Just another step, and you'll be telling me offspring can be produced not at the drawing board, by testing prototypes in a laboratory, with the highest concentration of the spirit in the metal, but in a bed, without any templates or training, at random, in the dark, and quite unintentionally . . .

Creation at this time, peopled as it was by primal deities whose whole energy and purpose seems to have been directed towards reproduction, was endowed with an astonishing fertility. The soil was blessed with such a fecund richness that one could almost believe that if you planted a pencil it would burst into flower.

In this way a process of evolution was started that led to the development of more and more complicated, self-reproducing organisms. The first primitive forms of life consumed various materials, including hydrogen sulfide, and released oxygen. This gradually changed the atmosphere to the composition that it has today, and allowed the development of higher forms of life such as fish, reptiles, mammals, and ultimately the human race.

We can define life as an ordered system that can keep itself going against the tendency to disorder and can reproduce itself.

A living being like you or me usually has two elements: a set of instructions that tell the system how to keep going and how to reproduce itself, and a mechanism to carry out the instructions.

A living being like you or me usually has two elements: a set of instructions that tell the system how to keep going and how to reproduce itself, and a mechanism to carry out the instructions. In biology, these two parts are called genes and metabolism.

I was so furious, you see, that all around me were things that could move and bend and grow and reproduce, and my son- my vital, charismatic, beautiful boy- was just this thing. Immobile, wilted, bloodied, suffering.

I do think everyone would be a lot happier if we laid eggs on our own and could just have friendship and didn't need to mount and penetrate one another.

Doc, God help me for saying it—if you repeat this I'll totally deny it—but some sperm deserve to be drowned before they get a chance to swim.

Oh, yes?" Lizardstripe mewed. "What a miracle. If I'd known toms could have kits, I would have made Mudclaw have these brats of mine himself.

Viable offspring capable of reproduction resulted from all these liaisons and in August 2018, Denisova Cave obliged yet again by yielding up a bone fragment, more than 50,000 years old and in sufficiently good condition for genome sequencing. It turned out to have belonged to a female, about 13 years of age, who had a Neanderthal mother and a Denisovan father.57

almost every living cell there was already a functioning computer with a huge memory? A mammalian cell had a DNA complement of several billion base pairs, each acting as a piece of information. What was reproduction, after all, but a computerized biological process of enormous complexity and reliability?

There's a singular kind of desperation that links all of us who cannot conceive but think of nothing else. I wonder about us. What has made that message play over and over inside our heads? Is it biology? I want it to be that. I want the reason I sit on the toilet, hoping against hope, to be biological and not some kind of mental disorder.

Is it a recent occurrence that women have tried to control when and if they reproduced? Absolutely not. By 2000 B.C., there was worldwide use of herbal potions to prevent pregnancy. Condoms were made from animal bladders.

There are lots of different strategies that an animal can use to survive. What a worm does is try to convert food into worms as soon as possible. In three days a single worm produces 300 progeny. So why put your resources into developing if you can make a brand-new worm in no time at all?

I've always worried that one day women would figure out how to get along without us and they would be able to reproduce unilaterally, like sponges.

If you took some famous religious leader, for example, and said it would be nice to clone them indefinitely so you have a dynasty of leaders, my own guess would be that each time the cloning takes place, they would become more and more defective, presumably mentally defective and subsequently worse.

The term 'epitaph' itself means 'something to be spoken at a burial or engraved upon a tomb.' When an epitaph is a poem written for a tomb, and appears in a book, we are aware that we are not reading it in its proper form: we are reading a reproduction. The original of the epitaph is the tomb itself, with its words cut into the stone.

Every batch of sperm represents an opportunity for genetic typos - called de novo mutations - to be passed on. A 20-year-old man and woman will each pass on about 20 de novo mutations to a baby they conceive. By the time the couple is 40, a woman's total has remained at 20, while a man's has jumped to 65 - and it keeps climbing from there.

human memory is not merely the repository of information in the brain. It is much more than this, and something that a machine can never be: a power, a force by which we mentally reproduce not just information but also our experiences, by which we shape our perceptions, introspect, interpret and analyse the direction our life has taken.

Sexual intercourse is the only purely reproductive sexual practice and if it is engaged in by women only when they wish to procreate then reproduction is under women's control. Once sexual intercourse is established as compulsory then women have recourse only to artificial contraception, abortion, and infanticide, to control reproduction and childbearing.

But you know what they say about Gutshot: the population never goes up and never goes down, because every time a woman gets pregnant, a man leaves town.
