Cultural Change in Technology
As our modern dinosaurs crash down around us, I sometimes wonder what kind of humans will eventually walk out of this epic transformation. Trump and the populism that’s rampaging around the world today, marked by xenophobia, racism, sexism, and rising inequality, is greatly amplified by the forces the GDE has unleashed. For someone like me who saw the power of connection build a vibrant, technologically meshed ecosystem distinguished by peace, love, and understanding, the polarization and h...12 DEC 2017 by ideonexus
The Disruptive Nature of Homo sapien's Rapid Rise to Apex...
Genus Homo’s position in the food chain was, until quite recently, solidly in the middle. For millions of years, humans hunted smaller creatures and gathered what they could, all the while being hunted by larger predators. It was only 400,000 years ago that several species of man began to hunt large game on a regular basis, and only in the last 100,000 years – with the rise of Homo sapiens – that man jumped to the top of the food chain. That spectacular leap from the middle to the top ...19 FEB 2015 by ideonexus
Growing a Forest Rapidly
1. First, you start with soil. We identify what nutrition the soil lacks. 2. Then we identify what species we should be growing in this soil, depending on climate. 3. We then identify locally abundant biomass available in that region to give the soil whatever nourishment it needs. This is typically an agricultural or industrial byproduct — like chicken manure or press mud, a byproduct of sugar production — but it can be almost anything. We’ve made a rule that it must come from...24 DEC 2013 by ideonexus
Umwelt
In 1909, the biologist Jakob von Uexküll introduced the concept of the umwelt. He wanted a word to express a simple (but often overlooked) observation: Different animals in the same ecosystem pick up on different environmental signals. In the blind and deaf world of the tick, the important signals are temperature and the odor of butyric acid. For the black ghost knifefish, it’s electrical fields. For the echolocating bat, it’s air-compression waves. The small subset of the world that an ...Folksonomies: perception senses
Folksonomies: perception senses
David Eagleman on how each species of animal senses only a small portion of the world, and assumes that small fraction is the entire world.

Seeing the Species for the Ecosystem
The authors comment that from this perspective, it could be stated that multiccellular beings are also ecosystems. That is, we are formed by different types of cells that cooperate and compete for resources; we are colonized by diverse types of bacteria (in the intestines, in the skin, etc.) whose activity is linked to other processes in our organism: we are invaded by viruses, which can be harmful or can take part in processes that regulate our DNA. "These beings are constantly being changed...It is helpful to think of species in the context of the ecosystem in which they live, as they are an part of it, indistinguishable from it in very important ways. Any single species' ecosystem includes all of the other species within it.
