This would also mean that psilocybin-less fungi would have found no need to maintain it, and may point to the occurrence of negative selection. WebGenetic data sets are used to see if biological races exist in humans and in our closest evolutionary relative, the chimpanzee. Change). Your second tradition (if you build an immediate temple/monument this should be before your first colony ships is even done) gives you 10% habitability empire wide allowing you to colonize those low habitability worlds. For instance, we might expect evolutionary change in adaptive radiations to be driven by the availability of ecological niches. This means that brow ridges in archaic humans must have had a social functionmost likely used to display social dominance, as is seen in other primates.

In discussing the biology of the mushrooms, he writes: 'Even if psilocybin in mushrooms began as 'an accident of a metabolic pathway', the fact that it wasn't discarded during the course of the species' evolution suggests it must have offered some benefit.'.

Basically: there's a lot of techs that boost habitability and terraforming isn't that expensive, so it's a negative trait with a relatively limited impact. (LogOut/ If you imagine a smallish population that suddenly expands (say, starlings in the Americas, or humans in the past few thousand years), the original genes are going to expand no matter what - even useless, or mildly harmful, genes will be carried along on the overall success of the rest of the organism.
