Octopus and squid make strange evolutionary shortcuts in adaptation. Evolution is an intricate process of change.

According to Science Alert, species of squid and octopus may yet have some surprises in store for us. “In a surprising twist, scientists discovered that octopuses, along with some squid and cuttlefish species, routinely edit their RNA (ribonucleic acid) sequences to adapt to their environment,” the article said.

“When an organism changes in some fundamental way, it typically starts with a genetic mutation—a change to the DNA. Those genetic changes are then translated into action by DNA’s molecular sidekick, RNA.”
