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! :-)

    By 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. :-)

Student of the Year

Image
As a toddler, my daughter loved Alia Bhatt’s songs, esp. the ones from Student of the Year . (That movie did have many good songs and well-choreographed dances). Fast forward to present day, when she is 12 yo. She rarely watches Hindi movies now, but one of the few ones she likes of late, Raja aur Rani ki Prem Kahani has, yes, Alia Bhatt.   If I had any hopes that there was anything to be read in the name of her toddler-time favorite ( Student of the Year ), they have been dashed. Our conversations come exam time are perfectly captured by this photo and its caption: In fact, the pic below captures how she and I look at her answer sheets – me intently, she with an expression of “It’s over, so why are you even looking at it?”   Of late, we pull her leg and tell her that she isn’t showing any signs of academic prowess, she’d better find a rich guy to marry. Some time later, she showed us this meme on the Internet: “Me No Study, Me No Care Me Go Marry Millionaire If He Die

Animal Senses #7: Touch and Remote Touch

Instinctively, we think touch is based on contact. Not entirely true, explains Ed Yong in Immense World – there’s a more important aspect than contact: “These incredible feats are possible through movement. If you rest a fingertip upon a surface, you can get only a limited idea of its features. But as soon you’re allowed to move, everything changes. Hardness becomes apparent with a press. Textures resolve at a stroke.” As you run your fingers over a surface, they hit the tiny peaks and troughs and set off vibrations in the mechanoreceptors at their tips.   At the tip of its snout, the star-nosed mole has many pairs of hairless appendages. It uses them to touch things around itself. Alive or dead? Food or ignore? It does these movements at an insane speed. In the time it takes to blink our eyes, the star-nosed mole can probe, identify and swallow its food. “Light may be the fastest thing in the universe, but light sensors have their limits, and the star-nosed mole’s sense of

The Retort of the "Luxury Person"

Image
Coming up with biting and witty retorts. It’s something we dream of, but rarely manage to pull off. Worse, the more we stew over the offending remark, the more likely we are to come up with that dream retort, as Calvin ruefully points out: During our last holiday at the Taj Resort, seeing my wife carrying towels to our poolside chairs, one of the kids there mistook her for a member of the staff and asked for a towel. When my wife narrated this to us, I did not imagine that my 8 yo daughter would come up with her own retort. But a day later, my daughter recapped the incident, an incident that didn’t even involve her in the first place , and said, “You know what I’d have told that kid who asked for the towel?”. And without waiting for an answer, she told us anyway: “I don’t work here. I too am a luxury person who is living at this resort. Go get your own towel.” We were highly amused by the phrase she had coined: “luxury person”. It certainly captures the kind of holid
