Human Ancestor 'Lucy' Was a Tree Climber, New Evidence Suggests

Lucyimage.JPG

Since the discovery of the fossil dubbed Lucy 42 years ago this month, paleontologists have debated whether the 3 million-year-old human ancestor spent all of her time walking on the ground or instead combined walking with frequent tree climbing.

Study Explains Evolution Phenomenon That Puzzled Darwin

Abrams-Taurusscarabbeetles.jpeg

Why do some animals have extravagant, showy ornaments -- think deer antlers, peacock feathers and horns on beetles -- that can be a liability to survival? Northwestern University researchers have a possible explanation for this puzzling phenomenon of evolution.

The new millipede also has bizarre-looking mouthparts of a mysterious function, four legs that are modified into penises, a body covered in long silk-secreting hairs, and paired nozzles on each of its over 100 segments that squirt a defense chemical of an unknown nature.

Ancient Hominid 'Hanky Panky' Also Influenced Spread of STIs

With recent studies proving that almost everyone has a little bit of Neanderthal DNA in them----up to 5 percent of the human genome--- it's become clear our ancestors not only had some serious hominid 'hanky panky' going on, but with it, a potential downside: the spread of sexually transmitted infections, or STIs.

Remember dropping your milk teeth? After a lot of wiggling the tooth finally dropped out. But in your hand was only the enamel-covered crown: the entire root of the tooth had somehow disappeared.
