thin but luxuriant biosphere of Earth, it stretches the mind to think that life would be difficult to find elsewhere. Only a century ago it was possible to imagine that creatures similar to
humans might live on our neighbouring planets, but a century of investigation has yielded no totally convincing evidence for extraterrestrial life. It surely exists, but it has not been easy
to find. The search is complicated by the probability that environments as favourable as Earth's are not common in the Universe, and it is likely that life elsewhere will not be nearly
as obvious as it is in our fecund biosphere. Instead of looking for people, Klingons or Wookies, the search will probably have to concentrate on detecting bacterium-like organisms similar
to those that have dominated more than 80% of the history of life on Earth. This is a preview of subscription content, access via your institution ACCESS OPTIONS Access through your
