Fermi and the Paleozoic
Jan. 14th, 2006 04:38 pmOne of the problems SF writers have [1] is the Fermi Paradox. Obviously beings like us can exist, because we do, but we tend to rearrange our environment to suit us and nobody appears to have done that to Earth before we showed up [2].
One solution is that for some reason species like us are very, very rare. Worlds with complex life might be quite rare, for example. Earth seems to have got along fine without them for the first four billion years, after all. This has the downside of making the galaxy a rather boring place, at least biologically (Yes, happy playtime for microbiologists but they're a bit odd).
Is there some intermediate between Slime Worlds and the Oddly Sychronized Competition?
Let's abuse this quotation.
To quote Carlos' summary:
"Rough translation: life on land, until about 250 million years ago, was to modern land-based ecosystems much like what a mercantilist, caste-based economy is to a modern market economy. You know the kind: this ethnic group does this, while that ethnic group does that, and those guys? they take care of the horses; and there's never a winner without a loser."
And my question is: does the modern system manage to innovate faster than than the one prior to the Permian? Because if it does, I could then handwave that whatever happened 250 million years ago was unusual enough that it hasn't been duplicated elsewhere so while complex ecosystems exist, it takes them so long to toss up a species like ours that we showed up first.
Which suggests a setting, some world of a dimmer (and therefore more stable) star, one that has had complex life for much longer than the Earth, but with a regime thematically similar to Earth -250M. There are large lifeforms but the over-all diversity is smaller and the niche space exploration more caste-like.
I need to go think on this.
1: I joke, of course. A high percentage of SF writers never ask the question "If FTL is possible and there are and have been for some time advanced civilizations in the galaxy, why wasn't Earth exploited back when trilobites were cutting edge?" If the Highly Capable Guys over at Tau Ceti reached the FTL handwavium level 1% earlier than us in this history of the universe, then they'd have a head-start of over one hundred million years. A difference of 1% is almost simultaneous.
2: Aside from terrestrial species, of course.
