Why doesn’t any animal have three legs?

If ‘Why?’ is the first question in science, ‘Why not?’ must be a close second. Sometimes it’s worth thinking about why something does not exist. Such as a truly three-legged animal. At least one researcher has been pondering the non-existence of tripeds.

“Almost all animals are bilateral,” he said. The code for having two sides to everything seems to have got embedded in our DNA very early in the evolution of life — perhaps before appendages like legs, fins or flippers even evolved. Once that trait for bilateral symmetry was baked in, it was hard to change.

With our built-in bias to two-handedness, it can be hard to figure out how a truly three-legged animal would work — although that has not stopped science fiction writers from imagining them. Perhaps trilateral life has evolved on Enceladus or Alpha Centauri (or Mars!) and has as much difficulty thinking about two-limbed locomotion as we do thinking about three.

This kind of thought experiment is useful for developing our ideas about evolution, Thomson said. (1)

How fascinating.

Everything started with Nothing.

Then One came into existence.

We are still in the phase of Two…

And there is no way to get any further.

For going further means that we get to three.

And from there infinity is one step away.

Leading to nothing more than zero once again…

But there is no infinity.

There is no two.

Not even One.

For only everything exists.

Infinity!

In the palm of a small kid…

Touching the untouched.

Jellyfish are about 95% water, which makes them very difficult to study because most of the underwater tools available to marine biologists are clunky, heavy, and often shred jellyfish and other delicate creatures to pieces. A new ultra-soft gripper uses fettuccini-like ‘fingers’ inflated with water to gently grasp jellyfish and release them without harm, allowing scientists to safely interact with them in their own habitat.

We touch things to experience them.

We see things to view them.

And what we see and touch is there. Never going away. Stable environment for scared little humans. Search the depth of your soul. It is what you don’t see that shapes your being. It is what you cannot touch that really touches you back. It is what you can touch that you cannot really touch. Because it is there only because of the things you can never touch.

Try to touch the cosmos…

Don’t be afraid.

It is afraid of you!

You are the raging abyss. Pouring out into existence.

Existence that should never be there in the first place.

Touch the cosmos!

Break it into pieces!

See?

You are still here…

Listening to music. Humans. Apes.

In the eternal search for understanding what makes us human, scientists found that our brains are more sensitive to pitch, the harmonic sounds we hear when listening to music, than our evolutionary relative the macaque monkey. The study, funded in part by the National Institutes of Health, highlights the promise of Sound Health, a joint project between the NIH and the John F. Kennedy Center for the Performing Arts that aims to understand the role of music in health.

“We found that a certain region of our brains has a stronger preference for sounds with pitch than macaque monkey brains,” said Bevil Conway, Ph.D., investigator in the NIH’s Intramural Research Program and a senior author of the study published in Nature Neuroscience. “The results raise the possibility that these sounds, which are embedded in speech and music, may have shaped the basic organization of the human brain.” (1)

Yes, we are the only ones listening to music.

Because our mind is never here.

We love traveling to the stars.

Only because we detest the Earth on which we were born.

We will learn one day.

When we reach the stars.

That those bright small dots we will see.

Is our home.

Which we have left a long time ago…

The evolution of… evolution.

New research identifies a previously overlooked global event which changed the course of the evolution of life in the oceans. It coincided with a rise in calcium carbonate-secreting plankton and their subsequent deposition on the ocean floor.

The ocean as we understand it today was shaped by a global evolutionary regime shift around 170 million years ago, according to new research.

Until that point, the success of organisms living within the marine environment had been strongly controlled by non-biological factors, including ocean chemistry and climate. However, from the middle of the Jurassic period onwards (some 170 million years ago), biological factors such as predator-prey relationships became increasingly important.

Writing in Nature Geoscience, scientists say this change coincided with the proliferation of calcium carbonate-secreting plankton and their subsequent deposition on the ocean floor.

They believe the rise of this plankton stabilised the chemical composition of the ocean and provided the conditions for one of the most prominent diversifications of marine life in Earth’s history. (1)

Evolution evolves.

And through the ages of existence.

Even Being redefines itself.

Eternal change.

Towards a goal which keeps shifting.

Everlasting life.

Walking a road that keeps going.

Poor man.

How much do you really need to walk into the clearing?

Before you realize you shouldn’t have left the clearing?

Look up.

You haven’t walked a single step.

Asteroids. Death. Opportunities.

When the asteroid hit, dinosaurs weren’t the only ones that suffered. Clouds of ash blocked the sun and cooled the planet’s temperature, devastating plant life. But fungi, which decompose dead stuff, did well. So what happened to the lichens, which are made of a plant and fungus living together as one organism?

“We thought that lichens would be affected negatively, but in the three groups we looked at, they seized the chance and diversified rapidly,” says Jen-Pang Huang, the paper’s first author, a former postdoctoral researcher at the Field Museum now at Academia Sinica in Taipei. “Some lichens grow sophisticated 3D structures like plant leaves, and these ones filled the niches of plants that died out.” (1)

Some die. Some live.

Should the first worry about living?

Should the latter worry about dying?

You are what you are.

You do what you do.

In the cosmos chess of existence, every move is valid.

For the game is fixed. And at the end, we will all go back to the beginning.

How can we do something we have not done already?

Dying. Only because we have lived.

Living. Only because we have died.

The chessboard. Look at the chessboard! This is the game!
