There’s an entire literature discussing which animals – besides us, humans, are able to use tools.
Most authors also make a clear distinction between the animals which just pick an object and transform it into a tool by using it as such and the animals which actually transform the future tool according to the intended use.

The difference between using a twig ‘as it was found’ and sharpening it first with the teeth.

This morning, watching some birds while having my breakfast, I just realized that the vast majority of them are superb tool makers. Them birds, I mean. Not just the heavily publicized Caledonian Crows….

I repeat. Most of them.
Most of them are superb tool makers.

Most birds are nest builders.
In fact, they not only build houses, of sorts.
They are building uteri. Or uteruses, if you prefer this spelling. Places where eggs are laid and cared for.

What more elaborate tool is there?

What next?

Crows are deemed to be the smartest birds around.

“Crows are the hominins of the bird kingdom,”
“Like our own ancestors, they evolved proportionally massive brains by increasing both their body size and brain size at the same time, with the brain size increase happening even more rapidly.”
Dr. Jeroen Smaers

Crows have also witnessed our evolution.

All life transforms its habitat.
Living things actually pass ‘segments’ of their habitat through their digestive systems. Digest them. Consume the useful components and discard the rest. And, finally, excrete whatever their metabolism had turned the useful components into. Urea and carbon dioxide, to name but a couple. For us, mammals. Other living creatures contribute something else to their environments.

The blue-green algae of yore are believed to have produced the oxygen we breathe now.
Wolf Reintroduction Changes Ecosystem in Yellowstone“.
Humans alter their ‘nesting’ places in ways sometimes detrimental to their own well being.

So, basically, we – as a society, actually ‘digest’ our planet. Our home… Our only home!

Are we happy with the results?

Are you happy with what you’ve done to your home?
To OUR home?
