You’re killing me Smalls.
Good catch. And I’m glad you did because that dragon fly story was stuck in long term memory!
***If you present a list of facts some of which are demonstrably false, it casts doubt on all the rest.***
The “list” was emailed to me from a dear old friend. It was clearly not encyclopedic material. In fairness, it has generated a lot of FReepers to do research....which is great exercise for the mind and memory.
The common fruit fly lifespan is about 30 days at 29 °C (84 °F).
Although it doesn’t show up on X-rays, your baby does in fact have kneecaps. They’re just not bony kneecaps. At birth, these kneecaps are still cartilage, and remain so for a few years. So all those spills and falls your toddler is taking aren’t going to be knee-breakers, just sponge-compressors. By the time your child is anywhere from 3 to 5 years old, those cartilage plates will have fully ossified into big-kid kneecaps, made of real bone.
“Babies are born without kneecaps. They don’t appear until the child reaches 2 to 6 years of age!”
Nonsense. Babies are born with kneecaps, but they are made of cartilage and do not fully harden into bone for several years.
“In the last 4,000 years, no new animals have been domesticated.”
Foxes were domesticated in Russia in an experiment started in 1959. There are other recent examples as well.
“If the population of China walked past you, in single file, the line would never end because of the rate of reproduction.”
It would be a neat trick for them to copulate and deliver babies while walking in single file, wouldn’t it?
“Leonardo Da Vinci invented the scissors.”
Scissors have been around since ancient Egypt and Sumeria. The modern type with the fulcrum in the middle was invented by the Romans around 100 AD, not by Da Vinci. Perhaps he refined the design, but he didn’t invent them.
“On a Canadian two dollar bill, the flag flying over the Parliament building is an American flag.”
No, it’s the “red ensign” flag, not the American flag.
Though it’s not a perfect list, it’s a fun and very interesting one. I notice that I’m not the only one who enjoyed it. Thanks for posting.
sorry, it was the American flag on some in the 80s
Spit my coffee out on that one. Has to be a joke in there somewhere :)
It is the mayfly that has a 24 hour lifespan.
Thanks for the link. Yes, that’s the US flag. I wonder how it happened? It’s hard to confuse the stars and stripes with a maple leaf.
I absolutely didn’t know that. You’re right, though:
Squashed mayfly can cause slippery road conditions, while motorists also had to battle poor visibility. Every year millions of mayflies hatch and sprout wings, but they only have a life expectancy of between 30 minutes to 24 hours. The mayfly life cycle lasts two years.
re: “Polish” and “polish”.
There is a manicure place nearby called the “Polish Spa” and I always mentally read it as the central European Slavic Nationality rather than the enamel that is painted upon the finger and toenails.
Thank You! (By the way,I don’t think Canada has had a $2 bill for many years, since they replaced it with the ‘toonie’.)
