This is a scary new study. If aliens exist, they would likely be a lot like us. Should we still want SETI to be a success?
(CSM)- When considering the prospect of alien life, humankind should prepare for the worst, according to a new study: Either we're alone, or any aliens out there are acquisitive and resource-hungry, just like us.
These two unpalatable options are pretty much the only possibilities, according to the new study. That's because evolution is predictable, and alien biospheres should thus produce intelligent creatures much like us, with technological prowess and an ever-increasing need for resources...
There is reason to be wary of such creatures, according to Conway Morris.
"If intelligent aliens exist, they will look just like us, and given our far-from-glorious history, this should give us pause for thought," he writes in the study, which was published today (Jan. 10) in the journal Philosophical Transactions of the Royal Society A.
