Set some time in the past. Heterosexuality has either been (inadvertantly) bred out or otherwise disappeared somehow. Simultaneously male couples and female couples gain the ability to produce offspring. The key sexual element of the bond between men and women which draws them to live together disappears,
and men and women gradually migrate and form separate civilizations. (Nations of mostly or exclusively men, nations of exclusively lesbians.) Book uses multiple characters jumping from years, to decades, to centuries, to millenia after the "event." Follows course of societal evolution and relationship between and divergence of the new male and female civilizations and the new relationships between individuals. Eventually ends a million years+ in the future when men and women have evolved into separate species of humans incapable of even theoretically reproducing together.

One of the first examples of feminist utopian fiction. Three male adventurers end up in an utopian state inhabited only by women, where everything is so much better than in the real world. Ripping good yarn, not. [jutta, Apr 30 2006]

Sounds like a decent premise for a novel but don't you think it would be a bit more believable set in the future rather than the past? Especially since us guys may be declared redundant and marked for deletion any time now. [Link] |

alternative history novels are all the rage it seems - i just did a magazine illustration for an article about harry turtledove who wrote a series of books on space lizards joining the nazi party just before WW2, and the ensuing alternative history. i havent read any of his books, but the whole idea of re writing the past is an interesting one. |
|
| |
Yeah, I read that book; all the vibrator factories took over. |
|
| |
I like this idea much more with the addition of the space lizards. +. |

The sequel to this book (about one million and twenty years from now) would feature each society -- the "men" and the "women" -- diverging into two sub-societies. No society of identical people can persist for long, because it is human nature to vary. After a decade or two, some men will have become femininer than their copats, and be ostracized; and some women will have become masculiner than their society, and be ostracized; then a third society will develop which will invite both ostracized subgroups and quite possibly be heterosexual again. |

Continued ad infinitum, it's Pascal's triangle existing in real life. |

Since we are talking SF, another plotline would be a society of cloners, who find sexual reproduction repugnant - akin to Huxley's Brave New World. Cloning eliminates genetic variation, which is fine for stable conditions but no good if you need to adapt. The question: to introduce genetic variation artificually with controlled mutation, or to reinvent meiosis and combine with other cloners? |
|

//the whole idea of re writing the past is an interesting one.// |
|
| |
Try reading 1984. The government regularly rewrites the past in their favor. |
|
| |
//find sexual reproduction repugnant - akin to Huxley's Brave New World// |
|
| |
1984 is a better match. Sex is glorified in Brave New World, only procreation is shunned. Any sex is considered vulgar in 1984, but is seen as a necessity for procreation until better methods can be developed. |

Would "Planet of the Apes" been a better movie if half the apes were gay ? |

Ooo! Oooo! How about this premise for high science fiction! This one would be best set in the distant past, to avoid confoundation by technology. Like good high SF this is a good story but is also a story about something else, told more cleanly by ditching the baggage associated with the something else. |

An alien parasite shows up, with the result that a certain percentage of children develop psionic powers at teenage and can do some mind control and other stuff of that sort. These psionic folks are a hazard to peaceful society as it exists and wreak havoc, so initially are put down or otherwise rendered harmless. |
|
| |
One society with a number of psionic adults with uses them to conquer its neighbors and control their resources. The only viable defense against this sort of attack is for each population to retain a population of psionics of their own, and try to set up cultural norms to stabilize societies containing populations of psionics. |
|
| |
For those who can do it, these cultural norms have benefits far beyond stabilization of populations containing psionics. Societies able to pull off this stabilization gain advantages far beyond simple stability. |
|
| |
The original idea might be found in some Samuel R. Delany works. |

Actually, it's possible that parthenogenesis in
humans has already occurred. The whole business
of meiosis is a bit of a mess in humans. It is just
possible that, somewhere, an egg has ended up
fully diploid (from the mother), and has been
triggered into development by fusion either with a
sperm lacking DNA (which happens, once in a
while), or by a sperm which it didn't fully fuse
with. In this case, a fully maternally-derived
embryo would develop. |
|
| |
Whether such an embryo would be viable or not is
a different matter - apart from recessive maternal
mutations, there's the problem of imprinting
(switching particular genes on or off, given that
there's a duplicate set in all embryos). |
|
| |
But I would be willing to wager that, if we
analysed the entire human population, we'd find
one or two parthenotes out there. |
|
| |
So, Jesus was a woman and a copy of Mary? That explains much. |
|
| |
As a Christian, I've long assumed Jesus was a female copy of
his mother. It helps me identify with him to think of him as
trans. |
|
| |
Ok: here is the challenge.
1. You have tissue samples from a large number of domestic animals. These animals are already closely related to one another because of inbreeding. |
|
| |
2. Assume you have no data on parental genotypes, only from the individual. |
|
| |
2. Using genetics, how could one identify parthenotes (new word for me!) in this population? |
|
| |
If the parents are very, very, very inbred (like some
lab rat strains), you might struggle. Otherwise, just
sequence the crap out of the genome of each
individual, and look for one that's completely
homozygous. |
|
| |
It would be female, assuming all the chromosomes
(including two Xs) came from the mother. |
|
| |
I suppose, in theory, you could have a male
parthenote. One
way would be if null-ploid egg (ie, one with no
chromosomes - probably extremely rare) got
fertilized
by a diploid sperm (no idea if they can exist - I
suspect not, because there's literally no room for a
double lot of chromosomes). Or a null-ploid egg
fertilized by a normal sperm, but then doubling-up
the chromosomes. Or a null-ploid egg fertilized by
two sperm. In the latter case, the offspring would
be partially heterozygous (since every sperm
contains a random selection from the two genomes
of the father), and might be perfectly normal. |
|
| |
There will definitely be some people out there who
are lacking at least one or two chromosomes from
the mother (and have an extra copy from the
father). Lots of eggs (like - tens of percent),
especially in women over 30, have missing or extra
chromosomes; and I'd bet that a small percentage
of sperm have extra copies of one or two
chromosomes. |
|
| |
Some of my work is with IVF (on the egg side of the
business), so I know that some pretty weird
chromosome-juggling can happen, at least on the
maternal side. |
|
| |
[Later] OK, a quick Google suggests that aneuploidy in the sperm of
healthy men is on the order of a few (1-4) percent, which is higher
than I'd expected. Assuming that it's uniform for all chromosomes
(and assuming that extra copies are as common as missing
chromosomes), that means on the order of 1/1000 sperm having an
extra copy of any given chromosome. |
|
| |
For women (across all age ranges - including young women), the
aneuploidy rate in eggs is very roughly the same as in sperm. So,
there's a 1/1000 chance of a given egg missing any given
chromosome. |
|
| |
That means that, in any fertilization event, there's a 1/1000,000
chance that the egg is missing a given chromosome, and the sperm
has an extra copy of the same chromosome. And a 1/1000,000
chance of its being the other way around (egg has extra; sperm
lacks). Add those up and multiply by 23 to allow for all
chromosomes, and you're up to 1/25,000. |
|
| |
So, 1/25,000 fertilized eggs should have both copies of one
chromosome coming from a single parent. |
|
| |
Now, depending on the nature of the aneuploidy (how it arises),
those two chromosomes may be identical or different (since each
parent has two different copies). If they're identical, there's an
increased risk of the offspring having some catastrophic genetic
disorder, through recessive mutations. So, let's guesstimate there's
a 1/2 chance of such an offspring surviving and being pretty normal. |
|
| |
Overall, then, you'd expect something like 1/50,000 healthy people
to have both copies of one of their chromosomes from the same
parent. |
|
| |
So, one in 50,000 of us is probably at least slightly parthenogenetic. |
