Two weeks ago it was quietly announced that the Future of Humanity Institute, the renowned multidisciplinary research centre in Oxford, no longer had a future. It shut down without warning on 16 April. Initially there was just a brief statement on its website stating it had closed and that its research may continue elsewhere within and outside the university.
The institute, which was dedicated to studying existential risks to humanity, was founded in 2005 by the Swedish-born philosopher Nick Bostrom and quickly made a name for itself beyond academic circles – particularly in Silicon Valley, where a number of tech billionaires sang its praises and provided financial support.
Humanity will change. Or be replaced. Or go extinct. An exploration of the many potential posthuman offspring of humankind, from the biological to the artificial.

What do you imagine when I say the future of human evolution?
Charles Darwin and his followers postulated that random accidental mutations of small effect plus natural selection over long periods would provide sufficient hereditary variation to explain biological diversity. Research since the middle of the twentieth century has unexpectedly shown that living organisms possess many different means of altering their genomes biologically, and these processes have been validated by DNA sequence analysis. In addition, the biological process of interspecific hybridization has become recognized as a major source of rapid speciation and genome amplification. Thus, it is time to shift our basic concept of evolutionary variation from the traditional model of slow change from non-biological sources to a fully biological model of rapid genome reorganization stimulated by challenges to reproduction.
Introduction
In Western society prior to the Enlightenment, there was little disagreement about the origins of biological diversity: it resulted from divine creation of an unchanging panorama of plant and animal species, as explained in Genesis. No thought was given to the idea that living organisms could change their fundamental natures. Even a scientist dedicated to analyzing the nature and classification of life forms, Carl Linnaeus (1707−1778), and one who documented the extinction of fossil organisms, Georges Cuvier (1769−1832), both believed in the fixity of species.

The Future of Humanity Institute announced last week that they have shut down. Located at the University of Oxford in the UK prior to its demise, the institute was one of the few places worldwide studying the risk of human extinction and a few other controversial research areas. Let’s have a look at the events leading to the institute’s closure.

How optimistic.
First, a little background. With 200 billion trillion (ish) stars in the universe and 13.7 billion years that have elapsed since it all began, you might be wondering where all the alien civilizations are at. This is the basic question behind the Fermi paradox, the tension between our suspicions of the potential for life in the universe (given planets found in habitable zones, etc) and the fact that we have only found one planet with an intelligent (ish) species inhabiting it.
One solution, or at least a way of thinking about the problem, is known as the Great Filter. Proposed by Robin Hanson of the Future of Humanity Institute at Oxford University, the argument goes that given the lack of observed technologically advanced alien civilizations, there must be a great barrier to the development of life or civilization that prevents them from getting to a stage where they are making big, detectable impacts on their environment that we can witness from Earth.
