Seeker of Patterns
Like adults, kids
become pattern seekers. It’s a good evolutionary technique to try and
understand what’s happening (or going to happen) in the world around us. Sure,
it is not fool proof, but it works enough times to be considered useful.
This kids’ book
titled Why? used that pattern seeking
tendency to amusing effect:
1)
Why do
zebras have stripes? Camouflage.
2)
Why do
leopards, jaguars and cheetahs have spots? Camouflage.
3)
Can
animals change their spots? Yes, arctic fox (brown fur in summer to white fur
in winter); octopus and squid (they can change to look like rocks or coral).
Why? Camouflage.
4)
Why do
polar bears have white fur? Camouflage.
5)
Why are
flamingos pink?
I am guessing you,
like my daughter, answered with a weary get-on-with-it “Camouflage” to the last
question. Unlike my daughter though, I am also guessing you did not say that they were pink to appear
like lotuses to predators.
Wrong, said the
book triumphantly, with that caught-you-sleeping tone (I imagine). Flamingos
are born with drab feathers:
“As they age, the flamingo’s plumage turns
pink from the bacteria and a vitamin-rich pigment call beta-carotene in the
bird’s shrimp-filled diet.”
The book followed
all this up with a “Silly Question, Serious Answer” section: Would my skin
color change if I ate like a flamingo? My daughter was intrigued since she
loves (eating) shrimp. Yes, said the book, all beta-carotene rich food
(including shrimp and carrots) cause a condition that causes the skin to take
on a yellowish tint. Of course, it added, you need to eat a lot for that to
happen.
Days later, when
my daughter was told to eat her carrots, she tried to wriggle out of it saying
she didn’t want to become like a flamingo.
I agree, munchkin,
it’s so hard to keep track of when pattern matching works and when it goes for
a six… flamingos are not pink for
camouflage, shrimp rich diet makes flamingos pink but us humans yellow, and the quantity that qualifies as “a lot” is
so different when applied to carrot v/s chocolates...
Makes cheerful reading. At the same time interesting biological detail is embedded in it too. The best part is: Aditi tried to wriggle out of it saying she didn’t want to become like a flamingo! :-)
ReplyDeleteBy the way, I have a doubt. People of the Mongolian race (Chinese and all) have a good fair skin and it has a slight yellow tinge. Is it due to some diet richness in some direction, such as beta-carotene stuff? The blog writer should find the answer when he goes next to China. :-)
