I saw this advertisement last night while watching TV. The Discovery Channel (U.S.) is having a special on Sunday night a 9:00 pm eastern about the new remains discovered.
Below is a link to an article about it. (I haven't seen it posted, so forgive me if it's a double post.) Basically, it's supposedly a skeleton that is 4.4 million years old, which is older than 'Lucy', and could change the way we think about how we evolved and where we separated from primates.
