I do not disagree with you, and my post does not make an claims or draw any conclusions, though I was responding to the original question: "how could you explain it today?" and to do that I felt it necessary to look at the "evidence" of the events to see whether a rational explanation was necessary. If the evidence was incontrovertable and a rational explanation could not be speculated then I admit I would be stumped for an answer, but as it is there is reasonable doubt in my mind.
History ("knowledge acquired by investigation") isn't an academic science as such in the same way that chemistry, biology or physics are, however it is the subject of scrutinised research and to the scientific method. What was taught as fact in history lessons 100 years ago is now treated with caution if there is no external supporting evidence - for example no one today believes Sir Francis Drake was playing bowls on Plymouth Hoe when the Spanish Amanda was spotted in the English Channel. As a historic document the bible should be treated the same way, as a religious scripture it can be treated however you like.

Whoa, a lot has happened since I last posted.
Epignosis, I find the way you interpret the Bible interesting. It's certainly not completely literal, but not entirely allegorical either. It makes me think of some kind of originalism when it comes to interpreting the US Constitution, although I don't know if that analogy is entirely accurate. I actually don't think it is one I've encountered before and if I have, the person didn't really make it explicit (the generic cherry-picking Christian).
I have honestly never heard this before two days ago when my friend said he encountered someone giving the same argument as you. Normally claims I see against evolution revolve around the complexity of the eye, brain, bacterial flagellum, etc. Have you done any research on this yourself? It's definitely a complex question - sexual reproduction can have a lot of mechanisms involved. So what problem do you see in it... Is it the fact that sexes exist at all and sex determination? Ovaries/testes? Penis/vagina or cloaca? All of it? |

You won't get any flames from me ... my only complaint about the post is that you completely and utterly fail to understand what evolution is, and how scientists arrive at the conclusion that it's the best explanation of how we all came to be. |

You should really read Dawkins' The Greatest Show on Earth. In it he explains evolution so well ... Edited by Mr ProgFreak - December 04 2009 at 16:33 |

What makes that book good specifically as a resource for information on evolution?

Yeah, my biology professor spent a week harping on the complexity of the eye and how it evolved...as though a Christian in the room asked. He also repeated lectures more than once (by that, I mean he gave them more than twice), and spent about two weeks telling us how the great flood never happened. He spit a lot when he spoke too. So it's probably reasonable to say I just had a bad biology professor, but man, did he have an axe to grind! So regarding genders...I preface this again by saying I am not as well-versed in evolutionary biology, and while others have attempted to answer my question, all of the answers were a bit too technical and far-fetched for me. It would just seem that asexual reproduction would be the most efficient- an organism wouldn't require a partner to mate and produce viable offspring. Obviously it isn't a problem, because we still have organisms that reproduce asexually today, and they exist in vast, vast numbers. Yet "somehow," some of these organisms began developing female sexual organs while some began developing male organs (or both at the same time, maybe). At what point would organisms gain the ability to reproduce sexually? It would have to be at the same time or before it lost its ability to reproduce asexually, or else the species would die out. And once the organisms could reproduce sexually, at what point in the evolutionary process did all of the parts work together to produce viable offspring? I mean, not only would the organisms have to also evolve the instinct to mate, but the mechanics of sexual reproduction and gestation are extremely intricate- if a part of the uterus hadn't evolved sufficiently, for example, the offspring might not ever be viable. |

There now exist species that can do both which solves your problem. Actually they've been around along time.
Even bacteria pass genetic material back and forth. Edited by Negoba - December 04 2009 at 16:00 |

No it doesn't. There is no "reason" (bad choice of word, I know, but I'm going with it) for organisms to evolve sexual reproductive organs, at least not one I can discern. That we have asexual organisms that flourish today makes me wonder why two different sexes evolved. It certainly isn't a more efficient way of reproducing, nor is it safer, nor does it help to ensure the survival of a species against the environment or predators. Then organisms, according to evolution as I understand it, would also have to evolve sex traits that would attract them to the opposite sex for breeding to happen. If this didn't happen overnight, at what point did it happen, and how? |

Juggling the genetic code in as many ways as possible allows for greater diversity of individuals. Greater diversity allows for greater chance for better fit with various environments.
Sexual reproduction started as a very simple process of genetic transfer long before there was anything we would call an "organ."
You're right that sexual reproduction is more energetically demanding than asexual reproduction. But all things that are more complex do. Especially in unicellular and simple multi-cellular lifeforms, the number of duplications (and potential for variation) is enormous. They get over the fact that 90% of the varieties being fatal by shere numbers.

I understand about genetic diversity, and I can also somewhat understand the simple process of genetic transfer...I just don't see any impetus for not one but two separate, extremely complex sexual systems that would not work (or work well) incomplete. And surely one or two mutations couldn't do the trick. But as I've said, this ain't my field. |

The fundamental question you're asking is a critical one though. What fuels the trend for more energy demanding, complex life forms?
It's that when the right random complexity meets the right environment, they have a field day, rapidly expanding and reproducing. An easier example is when alien species are introduced to new enviroments. The most common things that happen are A) They aren't suited and die or B) They have no natural competitors and go hog wild. A) is much more common. But we don't see the A) because they're all dead. We only see the B)'s and all their descendants.
I am highly skeptical that genetic mutations have a significant part to play in this story. Edited by Negoba - December 04 2009 at 16:18 |

Population forces, migration, and genetic reassortment are much more important than mutations in the diversity we see. Natural selection is poorly envisioned as primarily being a process between species. Though that occurs, what's much more important is the interaction of each individual species with its particular environment.
Mathematically, I loosely talk about a system's boundary conditions (the environment) and initial conditions (the species) and the chances that some equilibrium can be sound without runoff to zero or infinity.

It seems like you should have been paying more attention to what your biology professor was saying than to whether he spit during talking. |

My point was that he was a crappy professor...he was unprofessional as well, but I don't feel the need to go into that. Edited by Epignosis - December 04 2009 at 16:42 |

^ then you might consider my advice, get the book by Dawkins and read it ... then you'll know what we're arguing about here.

Nah...I'd rather just ignore the book and raise another argument. That's how things work around here, isn't it? |
