The algorithmic origins of life

The algorithmic origins of life | Science News | Scoop.it

Here, we propose that the emergence of life may correspond to a physical transition associated with a shift in the causal structure, where information gains direct and context-dependent causal efficacy over the matter in which it is instantiated. Such a transition may be akin to more traditional physical transitions (e.g. thermodynamic phase transitions), with the crucial distinction that determining which phase (non-life or life) a given system is in requires dynamical information and therefore can only be inferred by identifying causal architecture.

Sakis Koukouvis's insight:

New thinking in how life might have arisen on a lifeless planet, by shifting emphasis to the origins of information control, rather than, for example, the onset of Darwinian evolution.

Meet the molecule responsible for giving Earth all of its oxygen

Meet the molecule responsible for giving Earth all of its oxygen | Science News | Scoop.it
About 2.5 billion years ago, our planet had virtually no oxygen, and lifeforms were primitive. Then, oxygen levels suddenly spiked, the entire landscape of the planet changed, and we were on our way to complex life.
