Within the universe of Dune, people are one of many solely species we see. Might it’s that we’ve advanced on different planets, too?
The Dune universe appears to be dominated by a single species: people. Distinction that with, say, Star Wars – consider that notorious cantina scene – and also you would possibly surprise if Frank Herbert’s masterpiece is struggling to fulfill its variety quota.
After all, the Dune saga is about some 20 millennia sooner or later, and it’s not unreasonable to suppose that by then people could have travelled to each nook of area. However nonetheless, you must surprise the place all the opposite indigenous races are. Except for the sandworms on Arrakis, and one or two different fleeting examples, we see only a few.
Might it’s that our species is the principal indigenous race within the Universe – that Homo sapiens, or one thing near it, has advanced independently on a number of different worlds?
The late evolutionary biologist Stephen J Gould discovered this concept preposterous. He argued that for those who re-ran evolution right here on Earth – by no means thoughts on some bonkers planet 300 light-years away – then the likelihood of getting people a second time spherical is vanishingly small. His reasoning was that evolution is pushed by random units of genetic mutations, modulated by random environmental results, similar to mass extinctions, and that it will be extraordinarily uncommon for the very same set of results to crop up twice.
However it’s a view that’s not universally held. One college of thought, referred to as ‘convergent evolution’, says that random results ultimately common out in order that evolution converges, tending to supply related organisms in any given atmosphere. For instance, flight has advanced independently on Earth not less than 4 occasions – in birds, bats, bugs and pterosaurs. Eyes might have advanced as many as 40 occasions.
One adherent of this view is Prof Simon Conway Morris, of the College of Cambridge. “Convergence is among the finest arguments for Darwinian adaptation, however its sheer ubiquity has not been appreciated,” he says.
“One can say with cheap confidence that the probability of one thing analogous to a human evolving is de facto fairly excessive. And given the variety of potential planets that we now have good motive to assume exist, even when the cube solely come up the fitting approach each 1 in 100 throws, that also results in a really massive variety of intelligences scattered round, which might be prone to be much like us.”
