Paleontologist Martin Lockley of the University of Colorado Denver led a research team that discovered what he called large “scrapes” in prehistoric Dakota sandstone in western Colorado.

Real life King-Kong may have been doomed by changing landscape—and own size

An ape thought to be the largest in Earth’s history died out because it couldn’t adapt or get enough food in a changing landscape about 100,000 years ago, scientists argue in a new study. The giant ape Gigantopithecus weighed an estimated 200 to 500 kg, or 400 to 1,111 pounds. That’s up to three times heavier than the largest living species of gorilla, the Eastern lowland gorilla.

Scientists found DNA-like molecule that assemble itself

Chemists say they have found a way to make a DNA-like molecule assemble itself in a pond-like setting—potentially suggesting a key step in how life originated. The researchers actually worked with a simpler molecule, called pre-RNA. It’s hypothesized to have eventually evolved into DNA—one stopping point along the way having been the creation of a third substance, RNA, still used in the body to translate the code inscribed in DNA.

Chitchat and small talk could serve an evolutionary need to bond with others

We think of chitchat and small talk as the things people say to pass the time or kill an awkward silence. But new research suggests these idle conversations could be a social-bonding tool passed down from our ape-like ancestors.
