...what better place for a fun activity than the old bone yard? Though it may seem creepy to camp out in the cemetery, volunteers appear unfazed...
We’re v. happy we got more than a full dose of Sue this week, as we learned that she likes kicking children off her team at random, beef bone smoothies, and hovercrafts. We’re also enjoying the running joke about Will’s alleged perm, although we were shocked at Sue's violence toward a senior citizen. Also, we’re tickled that Sue was born in the Panama Canal Zone and still ran for office twice. Admirable...
...path of just such a discovery began in November 1994 with the unearthing of two pieces of bone from the palm of a hominid hand in the dusty Middle Awash region of Ethiopia. Within weeks, more than 100 additional bone fragments were found during an intensive search-and-reconstruction effort that would go on for the next 15 years and culminate in a key piece of evolutionary evidence revealed this week: the 4.4 million-year-old skeleton of a likely human ancestor known as Ardipithecus ramidus (abbreviated Ar. ramidus).

...Science doesn't put out special issues very often, and the extraordinary number and variety of fossils described in these new papers mean that scientists are arguing over real evidence, not the usual single tooth here or bit of foot bone there. "When we started our work [in the Middle Awash]," says White, "the human fossil record went back to about 3.7 million years." Now scientists have a trove of information from an era some 700,000 years closer to the dawn of the human lineage. "This isn't just a skeleton," he says. "We've been able...
...predator that would ultimately dominate North America and Asia. That probably didn't happen until larger predatory dinosaurs went extinct for other reasons, say the scientists, allowing Raptorex-like creatures to begin growing. Once they started to get into the league of the big predators, though, where speed and bone-crushing jaw strength would let them range farther and crunch the bones of the biggest prey, there was no competition at all. By about 90 million years ago at the latest, T. rex - or as we might now say, the king-size version of Raptorex - was unchallenged. "There...
