 This is Scientific American's 60-Second Science. I'm Steve Mirsky. Got a minute?

 
"Believe it or not, violence has been in decline for long stretches of time. And today we are probably living in the most peaceful time in our species' existence." Harvard psychologist Steven Pinker at the ScienceWriters2011 conference in Flagstaff on October 17th. His new book is The Better Angels of Our Nature: Why Violence Has Declined. 
 
"The decline of violence has not been steady. It has not brought violence down to zero. And it is not guaranteed to continue. But...it is a persistent1 historical development, visible on scales from millennia2 to years, from the waging of wars and genocides to the spanking3 of children and the treatment of animals."
 
One example is homicide rates. "It turns out that homicide records go back in Europe in many places for centuries...a medieval Englishman was at least 35 times more likely to be murdered than his modern counterpart. This is true not just in England, but in every European country for which statistics have been gathered."
 
Thanks for the minute. For Scientific American's 60-Second Science, I'm Steve Mirsky.
