Yesterday, Yohannes Haile-Selassie of the Cleveland Museum of Natural History and his colleagues reported finding a jaw in Ethiopia that belonged to an human relative that lived between 3.3 and 3.5 million years ago. Their article appears today in Nature.

"I attempted to repeat the experiment, however once my assistant discovered that I didn’t really have any tuna, she declined to participate in any further tests."
The Pliocene Pussy Cat Theory (which originally appeared in The Annals of Improbable Research) argues that the human ancestor Australopithecus domesticated cats for hunting, defense and harvesting static electricity to make it easier to climb trees. The theory, which was proposed by Lorenzo Love, is a parody of the Aquatic Ape Hypothesis (which is critiqued here and in shorter form here). Whether you know about the Aquatic Ape Hypothesis or not, the Pliocene Pussy Cat Theory, and Love's follow-up, the Subterranean Ape Theory, will completely alter your understanding of human evolution.
Ever since the famed Lucy skeleton was discovered in Ethiopia in 1974, there have been some unanswered questions. She was very tiny, and some researchers claimed it was unlikely that she (and, by extension, Australopithecus afarensis) could walk. Although other specimens were found throughout the 70s, none were more than bone fragments. Recently, researchers announced that they found another partial skeleton, and they believe it proves that afarensis was bipedal.
"So I called my dad over and about five metres away he started swearing, and I was like 'what did I do wrong?' and he's like, 'nothing, nothing - you found a hominid'."The remarkable remains of two ancient human-like creatures (hominids) have been found in South Africa. Some researchers dispute that the fossils are of an unknown human species, but others say they may help fill a key gap in the fossil record of human evolution. [more inside]
