Complexity and Trends in Evolution: A Closer Look

Explore the intricacies of evolution and artificial life, delving into the concepts of trends, complexity, and active versus passive evolution. Discover examples like malaria and Mycoplasma to understand how organisms evolve towards complexity through co-evolution. Uncover the challenges faced in artificial life simulations like Thomas Ray's Tierra and the quest for true "open-ended evolution."

Presentation Transcript

  1. Trends and Complexity In Evolution and AL Hunter Wroblewski

  2. Trends Random Fluctuation vs. A Trend (http://evolution.berkeley.edu/evolibrary/article/evo_54)

  3. Does Not Always Have a Direction • Misconception’s (higher organisms) • Simplicity vs. Complexity (rate of production) • Examples: Malaria and Mycoplasma • These parasites have dispensed of traits

  4. Towards Complexity • We also see that organisms evolve to become more complex • Typically through co-evolution (evolutionary arms race)

  5. Evolution: A response to survival • http://upload.wikimedia.org/wikipedia/comm ons/3/3b/Evolution_of_complexity.svg

  6. Active Vs. Passive • Evolution can be passive or active • Active- evolutionary self-organization • Passive- a response to a greater amount of biodiversity

  7. What do I think this means? • We find that this has proven troublesome in Artifical life. • We find this in Thomas Rays Tierra. With the absence of the fitness function. Like many other computer models the model at large begins to loop or ceases to evolve. • How do we produce true “open-ended evolution” or rather can we make sense of evolution?
