The joy of movement
While the evolution of movement was for survival (moving towards food, moving away from predators), no one can deny the sheer pleasure of moving, of dancing, of moving our bodies to the beat of music. Below, on the left, you can see a video of my pup playing in the mud on a spring day (with a smile on his face). On the right is a short piece I did at The Frederic Fleming House at W22nd Street in NYC for its residents. I love the participant to my right who is having so much fun listening to the music!
What I love about these videos is that it brings together seamlessly "Creatures on the move" for Vichaar and "Bharatanatyam for all.
Movement has many benefits for physical health e.g. to maintain cardiovascular health, to prevent falls, to help maintain balance, to manage chronic conditions, and to strengthen bones and muscles .
Movement has numerous benefits for mental health including improved sleep and endurance, stress relief, increased stamina, and increased alertness .
The positive impacts of movement inform my work with senior citizens to promote creative aging in a program called Bharatanatyam for All. The scientific principle of synaptic plasticity (the capacity of the brain to change with experiences), the positive impact of movement for mental health, and the power of self-expression lie at the core of my work; these benefits of Bharatanatyam are what I hope to distribute to all.
My inspiration for creatures on the move
My inspiration for Creatures on the Move comes from helping my mother take care of the stray animals around our apartment, and later working at Animal Help Foundation, a spay-and-neuter shelter in Ahmedabad, where I was responsible for taking care of hundreds of animals every day.
Another thing that attracts me to study animal movement is the sheer diversity in the pace, gait, and manner of movement that animals display. From the sinuous movement of the snake to a raptor soaring in the sky, to a squirrel that jumps around, the study of movement reminds me of Darwin’s take on the diversity he saw around him and noted in The Origin of Species [1,2].
There is grandeur in this view of life,
with its several powers,
having been originally breathed
into a few forms or into one;
and that, whilst this planet has gone cycling on
according to the fixed law of gravity,
from so simple a beginning
endless forms most beautiful and most wonderful
have been, and are being, evolved.
This sheer diversity in the lifeforms around us in terms of what they are, what they eat, and how they move is one of the things I love about teaching evolution at the American Museum of Natural History. After all, what could be more interesting than understanding and exploring the natural world? And how lucky am I to study and understand this beauty around us through science, and express it through dance?
In this series, we will look at birds, insects, worms, and mammals, explore their movements, and how these movements can be used in Bharatanatyam.
Hand gestures for some of these animals, e.g. pigeon and bee are routinely taught to students of Bharatanatyam. Gestures for fireflies, for example, are not routinely taught but exist in the Abhinaya Darpana , and. for animals like bats and squirrels, I developed the hastas through observation and experimentation. What I loved about this process was thinking of Bharatanatyam and the hand gestures we use to make up a living, breathing, evolving language.
In a future episode of Vichaar, I hope to talk about language acquisition, how we learn and retain languages, and how dance is a language where movement comes to life.
How do worms move?
I love seeing worms come out after a good rainstorm! On a recent walk, I found a worm (video above). While I am not sure about all details about the worm, I have been able to identify it to the best of my ability as an earthworm known as the 'Asian jumping worm'. These worms are known for their “theatrical” behavior as they thrash around when handled. (I was unable to confirm this though, as I didn't touch the worm) .
The Asian jumping worm is an invasive species that made its way to the US from East Asia. These small, unassuming worms are invasive creatures and can change the composition of the soil and “reengineer” the soil around them .
One may wonder if worms have brains. They do have brains, though they are not too complex. Earthworms (and leeches) fall under a phylum called the 'annelids' . The brains of segmented worms consist of two lobes, and the sensory and motor nerves originate from these cerebral ganglia (bundles of nerve cells) and reach the rest of the body .
Worms have a characteristic wave-like motion. The reason their movement is wave-like is that they have a segmented body. Worms have longitudinal muscles, circular muscles, and structures known as “setae” (bristle-like structures) on the outside of their bodies. Setae help the worms anchor to the location and repetitive contraction and release of muscles helps them elongate and contract their bodies, which helps them move .
Even a simple organism like the worm is so complex, so much so that the transparent roundworm Caenorhabditis elegans (C elegans) is routinely used to map the nervous system  and study aspects of aging  and longevity .
In the video on the top left, you will see an Asian jumping worm on its way in uptown Manhattan. The video on the top right shows my interpretation of the worm’s movement with my hands.
How bats move
Bats, the only flying mammals, have had a special place in my heart for a long time. At one 'Save the Birds' Campaign at Animal Help Foundation for the kite flying season of Uttarayan, we once rescued a baby bat that was trapped in kite strings. I still remember how soft the baby bat was as we were unraveling kite thread around its body.
Thanks to vampire lore, these magnificent creatures are universally hated, but they are critical for pollination of many fruits and crops we love – chocolate, mango, avocado - and they are critical for keeping the number of night insects in check . Bats have two adaptations that make them extremely special: powered flight and echolocation .
Bats belong to a group of animals called the Chiroptera (Kir-op-tera), which literally means “hand wing”. These nocturnal animals comprise 20% of the mammal species worldwide, and there are more than 1,300 species of bats currently !
The aerodynamics of bat flight is the topic of intense investigation. Their wings are actually structures like hands that are adapted for flight. If you see slow motion videos of how bats move (and these videos are absolutely amazing), you can see how they are using their wings to “swim” through the air.
While bats and birds both fly, the way they fly is very different. Additionally, the structure of bird feathers is quite different from that of bat wings. The wings of the bat offer intense maneuverability and they can even fold their wings. they move by “rowing” through the air. The maneuverability comes in the form of “up stokes” and “down strokes” that allows them to move much faster and in a much more agile manner as compared to birds .
Creatures on the move - an introduction
Episode 2 of Vichaar is all about movement. We looked at the neuroscience of movement, the types of movement in Bharatanatyam ranging from subtle, minute ones, to those that span the entire stage. In subsequent blog posts, I talked about the evolution of movement for survival, stillness and the complexity of staying still, saccades, and synaptic plasticity in movement as is evident by my Pup running on three paws.
The depiction of animals in Bharatanatyam is not uncommon - we routinely show Lord Kartikeya's peacock, Lord Ganesha's mouse, his elephant trunk and tusk, and the snake
For the upcoming episodes on the theme of movement, I will explore animals, the way they move, and how their brains and nervous systems make their movement possible. All the animals you will see in this series are from my neighborhood of uptown Manhattan, which speaks to the wonders of nature that reside right at our doorsteps!
I hope these posts make you think of your favorite animals, how their movement inspires you, and how you may evoke it in dance.
Movement of butterflies
We love butterflies for their color and joyful spirit. Butterflies are amazing creatures; we have all heard of the monarch butterflies flying as many as 2,000 miles to migrate to warmer climes, using geomagnetic cues. Sadly, a recent study just declared monarch butterflies as an endangered species .
For my dance world, butterflies provide an endless source of inspiration as far as the color combinations they exhibit - for example, how would these colors of blue and black look in a Bharatanatyam costume?
Butterfly bodies are different from those of birds, as they lack the rounded profile which provides lift to move through the air. Butterfly wings are short, wide, very large, and flat. Butterflies have evolved a unique way of moving through air called “cupping and clapping”. The flexible wings of the butterfly help it create a propulsive “clap” mechanism and moves it forward. The wings have a downstroke as well, which helps support their weight . A butterfly can also rotate its body in flight to control the direction of its flight . You can find a slow-motion video of a butterfly moving its wings here.
To the left, there is a video of a butterfly on one of my walks; to the right is my attempt of recreating its movements with my hands.
What does the butterfly symbolize to you?
