The greatest beauty in nature is symmetry!
In a Sketch of course the symmetry is difficult to maintain!
Most beautiful things in the world are radially symmetrical while more than 99 percent of living beings are actually not Radiantans!
Which brings us to the question what are who are Radiantans? Who are not Radiantans who form the majority?
By the way the ones who are not Radiantans are called Bilaterians! The chief difference is actually also in the way they walk!
Not catwalk by the way but the basic way they move!
So Radiantans or have radial symmetry while Bilaterians have bilateral symmetry!
Radiantans (Radiata) and Bilaterians (Bilateria) exhibit fundamental differences in mobility, largely dictated by their body symmetry and nervous system organization. Radiates are generally adapted for sessile, floating, or slow-moving lifestyles, while Bilaterians are adapted for active, directional movement!
Radiantans have a mobility which is limited, passive, or slow. Examples include jellyfishes (planktonic drifters), sea anemones, and corals!
Radial symmetry allows them to experience the environment equally from all directions, which is advantageous for sedentary organisms waiting for food, but not for chasing prey. Which means that those which have radial symmetry can move in all directions! Whilst those with bilateral symmetry can only move in two directions.
So Bilaterians have motility which is active, rapid, and directional (forward, backward, side-to-side). Examples include worms, insects, and vertebrates which is of course more than 99 percent of movement in the world!
Another interesting thing is that evolutionarily; both the Radiantans and Billaterans had a common evolutionary origin! In fact evolutionarily all were initially Radiantans!
Which essentially means that at some point in life you could go wherever you want but as you evolve you do only two directions! You can either choose to go front or back or you can choose to go up or down!
Whatever you select is your direction! Sometimes of course there is no right direction; it’s only a choice!
Like I choose to sketch Shankar Mahadevan! Really happy with the sketch after a long time!
Now keep your direction towards your bed and sleep!!
Shubh ratri!
