After the cold temperatures ice sheets and drop in sea level at the end of the Ordovician, the Silurian enjoyed a warmer and more stable climate. During this time, fish developed jaws, and the first animals adapted to a life lived entirely on land appear in the fossil record. Continue reading Ep 173: The Silurian period→
After the die out at the end of the Cambrian, during the beginning of the Ordovician, there was an increase in the variety of animals and plants, with many new species entering the fossil record. Chordates became fish, plants colonized the land, corals began forming reefs, and the cephalopods came into their own. At the end of the period, wild climatic shifts caused the second most severe extinction event in the history of life. Continue reading Ep 172: The Ordovician period→
In the Cambrian period, roughly 540 million years to 485 million years ago, most of the types of animals that are with us today got their start, even if it’s difficult to recognize them. Continue reading Ep 171: The Cambrian period→
Most of the history of life on our world is about single cells. Life made up of millions-billions-trillions of cells, (just for one critter!) only arrived in the last 700,000,000 years. Life in its single celled form got here 3,400,000,000 years ago. It took life nearly 3 billion years to learn the trick. Continuing the continuing story of Evolution, we look at the Precambrian, and the first multicellular life seen in the fossil record.
Today, I share a bit of what’s happened with my digital organisms, my ongoing experiments with some software-based artificial life I wrote, and talk about where we’re going next. The general system is very close to where I wanted it in order to implement, oh, just so many experiments. Since I’m attempting to use what I created to study and perhaps even generate intelligence, it’s time to get back to researching how intelligence evolved in the world of biology.
Cycle after cycle, they all do their next command, like the clicking of a master clock, beating out they’re digital days.
Each little digital creature, called a figure, gets a turn. That’s just enough time to do one command. It’s been more than 13 hours, and the current population is somewhere just above 310,000,000. They were randomly generated, and used the slow internal I/O—they can only read write cut or paste one number at a time. Continue reading Nearly there→
One of my populations, precodedshort.pop, isn’t acting how it used to. I have a vague memory of doing some experiment, and accidentally saving a population in that file, overwriting what was there. Yeah, I even recall how I could get it back, and thinking how it didn’t matter anyway, I’m done with it.
Right, the other possibility is that something got messed up somewhere in my system, and it isn’t running right, or the same, somehow. However, every other population is acting how it used to. Before I remembered, just now, that I’d changed precodedshort.pop, I wanted to do another test of the system, to be certain all was well. Continue reading It’s working! … oh… wait…→
