Brains and Tools
Brains and tools involve the composition, structure, and evolution of neurons and biological and artificial neural networks from the simplest animals to the human brain, their ability to process sensory input and to control motor functions, and the development of tools to analyze, observe, and control the environment and transform the Earth and its lifeforms. A reverse order logarithmic timeline covers the evolutionary history of brains and tools from 3.4 billion year old bacterial membrane proteins that controlled the flow of ions to two billion year old eukaryote cells that generated electrical signals to 600 million year neural networks to complex animal brains to modern machines with exceptional computational powers.
"Prove you're not a robot" - lecture on artificial intelligence, consciousness, and free will
Dr. Bob Field presented a research scholar's talk on November 1, 2016 entitled "Prove you're not a robot". The description of the talk is as follows: Our planet and our species evolved from elements that were formed in and dispersed by supernovas. Now our fate depends on rapid advances in robotics, genetics, artificial intelligence, and neuroscience. Where are we going, physically, mentally, and spiritually? Do you have free will? Can robots have free will? The 25 chart RUA Robot PowerPoint slide lecture can be downloaded.
A 30 minute narrated video of the lecture is embedded below. When you play the video, you can go to full screen and adjust the setting to 720 HD. Be prepared to turn the sound volume down when the Big Bang and Sophia Robot video clips play.The author's narration is a bit muffled and monotonic due to the quality of the laptop microphone.

Brains like these developed tools like Mathcad which feature animations including the one below of amplitude modulated and frequency modulated cosine curves.

The original video author says "The human brain contains over 100 billion neurons, and roughly 1 quintillion synapses. But how did it all get started? How did the first nervous systems, the first brains evolve? How did a bunch of simple cells evolve into a biological computer?" Below the video is a link to the original author.

Can the brain of one predator outwit the brains of dozens of prey?
The lioness in this home made video paced back and forth on the near side of the watering hole trying to decide what the best approach would be for a surprise attack on the herd of antelope in Tanzania. Ultimately the lioness failed.
The shaky video was produced from the safety of a range rover at some distance.
