To grow the kind of baby that we do, with this giant brain, who can't do anything for the first 3-5 years of life, you need a lot of input. As much as 1.5-1.7 million years ago, we start to see a shift in the fossils, which suggests that more than one or two individuals became closely involved in taking care of the young. Fast forward to the last couple hundred thousand years, and it is absolutely clear that the human success story is part and parcel of our incredible ability to "take a whole village" to raise a child, as the old saying goes. The nuclear family--Mom, Dad, a couple kids, and a dog--is not only very recent but is not even typical of the way most people live in the world.

Their squishy robotic hands can gather coral samples more delicately than robots, and in places humans can't reach. Developed with support from a National Geographic Innovation Challenge Grant, the hands were first tested in tanks in March 2015 and then taken to the Red Sea in May. After a successful expedition, Wood and Gruber hope the technology may have even broader applications.
