1. On Sex

‘Evolution is a Lie’ read the placard in the town centre the other day as Christian preachers took to ranting, again, about how everyone’s a sinner in need of Jesus.

I thought, if evolution is a lie then why is there sex? What would be the point of it in a world created by God?

While sex makes abundant sense in the context of evolution, it is difficult to explain in terms of Creationism. Why? Because sexual reproduction (as opposed of any other sort) exists specifically to ensure the shuffling and recombining of genes to produce variation in offspring. Why would a Creator (say the God of the bible, so beloved of Ken Ham and every other Christian) create the very mechanism that makes natural selection, and therefore evolution, possible? Why would he introduce a process that has no purpose but to serve as the engine of evolution? There wouldn’t be any need to, unless this deity specifically planned to develop life through evolution, or a process very like it.

But Christians like those street preachers and Answers in Genesis and its sycophants, reject the Darwinian model of evolution. So how do they explain sexual reproduction when it’s not only incongruous in a creationist scenario, but completely unnecessary? If not to drive evolution, why does sexual reproduction exist at all? It’s not, if I might pre-empt one possible response, because God thought we’d enjoy it; most living creatures reproduce sexually and ‘enjoyment’ is not part of their perfunctory copulation. Not to mention the fact that the Creator God of the bible spends most of his time objecting to and condemning sex.

2. On Life from Non-life

I’ve been told many times by Christians that, without God, life could not have got underway and subsequently evolved. Their argument goes like this: ‘inanimate chemicals are incapable of organising themselves into complex, self-replicating organisms,’ which makes me think, not of sex, but of viruses; non-living groups of chemicals that are highly organised self-replicators.

I’m not saying life necessarily developed from viruses, but they are evidence that inanimate chemicals are capable of acting as if alive, organising themselves to serve a collective purpose, namely self-perpetuation. The earliest viruses would not of course have been as complex as those today (viruses evolve too), but next time you have a viral infection, consider whether the difference between non-life and life is as great as it might seem. From what we do know, it wouldn’t need much, and certainly not a god, to turn one into the other.

More random thoughts on Evolution next time.
