Cephalopods, such as the squid and octopus, have long been known for their wily intelligence. Their complex behaviors include unlocking and escaping from aquarium tanks, opening jars, and communicating with one another using a system similar to Morse code. These underwater creatures, along with cuttlefishes, are all coleoids, which is a subclass of cephalopods. New research highlights another unique ability of these underwater creatures: they can edit their own RNA. [Read more…]

It’s time to rewrite the textbooks. Until now, the oldest known Homo sapiens fossils, found in Omo Kibish in Ethiopia, dated to 195,000 years ago. The new fossils, discovered in Jebel Irhoud in Morocco, date to approximately 300,000 years ago. This means the new findings predate the previous oldest-known fossils by over 100,000 years.
