As people put more carbon dioxide into the atmosphere, the oceans absorb more of it, and that's making the water more acidic.<p>The effects are subtle in most places, but scientists say that if this continues, it could be a disaster for marine life.<p>In fact, some scientists have taken a glimpse of what a more acidic ocean might look like.

Discoveries lead to new arguments over the details of how we became who we are.<p>But anthropologists generally agree on this much: A little more than 2 million years ago in Africa, the human lineage emerged.

Not much action going on — most reptiles and other coldblooded creatures take on the temperature of their surroundings, so they tend to be most sluggish when the outside temperature is cool. The monkeys, however, act like they've had one too many cappuccinos.

Large mammal migration in Africa has generally been hindered by the subdivision and fencing of land. However, this one remains possible because it takes place in a unique, multi-country wildlife corridor. <div class="fullattribution">Copyright 2014 NPR.
