Urey and Miller?

Some lifeforms can only live in certain environments. It may be an acidic one, hot, cold, alkaline, oxygen free, oxygen rich and so on. Those environments may be lethal to other organism. To say that any given environment is deadly to all life is just not valid. When bacteria first started to produce oxygen, some 3 billion years ago, it was lethal to most other organisms. The oxygen didn´t stay molecular for long as it reacted to iron but those first primitive algea were the first pollutors.

Urey and Miller may have gotten the proportions of the atmospheric gasses wrong, there probably wasn´t that much methane, but the experiment was sound. It proved life could have evolved as a result of chemistry alone. But the most important ingredient to make life is time. If Urey and Miller had kept their experiment running something living would have crawled out in about 100 million years...

A quick 'Google' of UK sites mostly throws up arguements against the idea, predominantly from religious/'star-child' organisations.

Of the few academic referals, Urey & Miller are still on the agenda.

I'll stick with academia.
