Fact: Cephalopods can edit their own RNA, rapidly tweaking protein outputs without changing DNA.
Explanation: Octopuses, squids, and cuttlefish show extensive A-to-I RNA editing in neural tissues. This flexibility may help them adapt to temperature shifts and complex behaviors, albeit at an evolutionary cost to genome evolution speed.

Fact: Honeyguide birds in Africa lead humans to wild beehives, then eat leftover wax and larvae.
Explanation: The greater honeyguide has a learned, mutualistic behavior with certain human groups who recognize its calls and follow it to honey. Studies show both birds and people use specific signals to coordinate the forage.

Fact: Crows can understand the concept of zero, treating it as a numerical quantity distinct from one.
Explanation: Behavioral experiments show corvids respond differently to no dots versus one dot, indicating abstract number processing. Few animals demonstrate this cognitive leap.
