Groucho's Fact Hunt



O dunno, someone told me theres none in Iceland because of the unique climate and the cold.
I think one of the reasons there’s so many ground nesting birds in NZ is cos of the lack of snakes and ground predators.
I remember being at a party once and asked about wha snakes he’d seen growing up in NZ and he just walked away in disgust. Still cringe about it now and then
 
There were loads of experiments done in the 60s and 70s around the idea of hereditary memory - that there is a physical, chemical basis to memories that are encoded in us like DNA.
Led by a guy called McConnell, he found that he could train some species of flatworms (planarians) to learn simple behaviours - then chopped them up and fed them to other flatworms, who then allegedly exhibited the same learned behaviour.

Massively exciting idea but ultimately came to nothing despite being extended to a lot of other animals, many papers - but the experiments couldn't be repeated.

 

We need a bit more research that that for this thread.
From National Geographic -
There are more than 3,000 species of snakes on the planet and they’re found everywhere except in Antarctica, Iceland, Ireland, Greenland, and New Zealand. About 600 species are venomous, and only about 200—seven percent—are able to kill or significantly wound a human.
