Shermer's last law
Shermer's last law is a conjecture put forth by American scientist, Michael Shermer:
It is Michael Shermer's modification of the third law of Arthur C. Clarke's famous three laws. It was first mentioned in Shermer's column Skeptic in the January 2002 issue of Scientific American Magazine.
Shermer formulated his law to point out that if humanity were to make contact with an extraterrestrial intelligence, they would probably be vastly superior to humans, because on an evolutionary timescale, an extraterrestrial intelligent species that was only slightly ahead of humanity biologically could be millions of years ahead of humanity technologically.
