Influenza A virus subtype H5N1 time-honoured theory into why atmospheric condition on globe convey remained stable plenty for life to evolve over billions of years has been given a new, innovative twist.

It champions the sentiment that living organisms together with their inorganic surroundings evolved together every bit a single, self-regulating organisation that has kept the planet habitable for life - despite threats such every bit a brightening Sun, volcanoes together with meteorite strikes.
However, Professor Tim Lenton from the University of Exeter together with famed French sociologist of scientific discipline Professor Bruno Latour are at in i trial argument that humans convey the potential to 'upgrade' this planetary operating organisation to practise "Gaia 2.0".
They believe that the development of both humans together with their technology scientific discipline could add together a novel bird of "self-awareness" to Earth's self-regulation, which is at the pump of the master copy Gaia theory.
As humans drib dead to a greater extent than aware of the global consequences of their actions, including climate change, a novel form of deliberate self-regulation becomes possible where nosotros trammel our impacts on the planet.
Professors Lenton together with Latour propose that this "conscience choice" to self-regulate introduces a "fundamental novel country of Gaia" - which could assist us accomplish greater global sustainability inwards the future.
However, such self-aware self-regulation relies on our mightiness to continually monitor together with model the country of the planet together with our effects upon it.
Professor Lenton, Director of Exeter's novel Global Systems Institute, said: "If nosotros are to practise a meliorate populace for the growing human population this century together with hence nosotros quest to regulate our impacts on our life support-system, together with deliberately practise a to a greater extent than circular economic scheme that relies - similar the biosphere - on the recycling of materials powered past times sustainable energy."
The master copy Gaia Theory was developed inwards the belatedly 1960's past times James Lovelock, a British scientist together with inventor. It suggested that both the organic together with inorganic components of globe evolved together every bit i single, self-regulating organisation which tin command global temperature together with atmospheric composition to keep its ain habitability.
The novel perspective article is published inwards journal Science. It follows recent research, led past times Professor Lenton, which offered a fresh solution to how the Gaia hypothesis plant inwards existent terms: Stability comes from "sequential selection" inwards which situations where life destabilises the environs tend to last short-lived together with outcome inwards farther alter until a stable province of affairs emerges, which together with hence tends to persist.
Once this happens, the organisation has to a greater extent than fourth dimension to larn farther properties that assist to stabilise together with keep it - a procedure known every bit "selection past times survival alone".
Creating transformative solutions to the global changes that humans are at in i trial causing is a key focus of the University of Exeter's novel Global Systems Institute.
