Chimps are physically stronger than humans, as demonstrated in recent national news when a chimpanzee severely mauled a Connecticut woman. Police were forced to shoot and kill it after its owner failed to subdue it with a knife from her kitchen.¹

Evolutionary anthropologists once thought that stone knives were developed in the late Stone Age, around 40,000 years ago. That figure was later revised to 200,000, around the Middle Stone Age, when stone blades were discovered in lower strata.

Researchers recently announced that they have unlocked some of the mystery surrounding the evolution of insect flight.¹ Their observance of a certain wingless insect led them to hypothesize that its “directed aerial descent” might be an important stage in flight evolution. But is it?

Arsenic is a common toxic component in pesticides and herbicides, and one place it is found naturally is in the hot springs of Yellowstone National Park. The arsenic in the water there would be deadly to many living creatures, yet the Cyanidioschyzon algae thrive in it because they are specially equipped to detoxify arsenic through chemical modification.

Scientists are hoping to revive a 50-year-old failed experiment that tried to discover how biological life could have originated from non-living chemical processes.
