thread_title: List of doomsday scenarios

message: I have removed speciation as a reason for space colonisation. Natural selection occurs when a species is challenged, when there is a threat to its survival, a threat to the continued existence of fertile descendants. Simply sending humans to Mars and waiting 100 000 years does not necessarily yield a different species. Since the dawn of agriculture, humans have not been subject to any significant evolutionary pressure. With the use of tools and fire, humans have not been genetically adapted to their environment, but rather have adapted their environment to them, by using the resources of nature to ensure not just survival, but abundance and comfort. If we colonise distant worlds, we are likely to settle more hostile places, like Mars or Europa, than Earth-like places, which must be rare in the universe. Humans, humans' pets, humans' parasites and complex life in general are unlikely to be able to adapt to the 95% carbon dioxide atmosphere of Mars or to the -160 ºC temperature of Europa. In colonising space, humans will not have direct contact with the hostile worlds they inhabit; instead, they will live inside domes and use space suits to work on the outside. Therefore, there is no reason to believe Martian humans 100 000 years from now will be much physically different from us, ordinary Earthlings.Halfleaf (talk) 06:01, 17 August 2009 (UTC)

The article currently ends as such. Does anyone know how it should end? —Preceding unsigned comment added by 216.124.224.52 (talk) 01:06, 22 January 2010 (UTC)
