A new Homo erectus fossil suggests that females had large, wide pelvises in order to deliver large-brained babies.
Being born with a larger brain meant our ancestor became independent far more quickly than modern human infants.
The new finding, published in Science magazine, conflicts with earlier ideas that suggest they had a tall, thin body shape adapted for running.

I have often been involved in arguments about the Israeli-Palestinian conflict that focus on its history. Usually, the defender of current Israeli behavior urges the importance of appreciating all that Israel has been through and why it exists in the first place. I respond by reviewing the dispossession of 1948, terror attacks on Arab villages in the ’50s, Israeli provocations over the DMZ on the Golan Heights in the ’50s and ’60s, and on and on. Eventually and invariably, the defender of Israeli behavior insists that we not be so distracted by the history, that we need to focus on resolving the current conflict, not rehearsing the past. And thus we are struck by a larger question: is the history of Israeli-Palestinian relations important in our attempts to solve the present problem?

One sunny day in 2009 an old man approaches the White House from across Pennsylvania Avenue where he’s been sitting on a park bench. He speaks to the U.S. Marine standing guard: “I would like to go in and meet with President Bush.” The Marine looks at the man: “Sir, Mr. Bush no longer is president, and no longer resides here.” The old man says, “Okay,” and walks away. . .

This is experimental confirmation of a type of anecdotal fallacy, that is, the tendency of people to think that events which receive media attention are more common―or, in this case, more dangerous―than they are.
