Tony Crayfish Evolution

What happens when a pond becomes an evolution laboratory? Tony Crayfish Evolution brings a colorful world of evolving creatures to your Mac, iPhone and iPad. Watch as a naturalist, experiment with their genes, or challenge populations to survive a changing environment. Every creature carries an inherited genome. Mutations introduce variation, mating combines parental genes, and natural selection emerges through feeding, survival and reproduction. A successful lineage may flourish, diversify—or disappear. WATCH A LIVING POND Observe herbivores, omnivores, predators and parasites competing for resources. Follow an individual and its descendants. Discover how body size, armor, movement, diet and reproductive strategies shape life in different habitats. EXPLORE GENES AND INHERITANCE Inspect paired chromosomes and edit alleles. Create and save organism presets, then introduce them into a pond. Adjust mutation frequency, mutation magnitude, recombination and mating preferences. Explore outcrossing, self-fertilization, or a strategy that combines both. Optional gene regulatory networks add another layer: inherited networks respond to local conditions and influence aspects of a creature’s physiology and behavior. TAKE ON FOUR CHALLENGES • Pond Biomass & Diversity: build a thriving ecosystem. • Establish a Lineage: introduce your organism and follow its descendants. • Mount Improbable: evolve through a succession of environmental obstacles. • Combination Mount Improbable: explore separate routes, contrasting adaptations, and the challenge of bringing useful traits together. Review your results, inspect successful summit creatures, and modify previous setups for another attempt. ASK QUESTIONS THROUGH EXPERIMENTS Does mating help populations adapt? When is selfing advantageous? How do mutation and gene regulation affect outcomes? Run matched experiments across random seeds, compare trajectories, and examine statistical summaries. Results emerge from the simulation: no reproductive strategy is guaranteed to win. SEE THE STORY BEHIND THE NUMBERS Explore population histories, genetic and phenotypic diversity, food webs, ancestry and adaptation along the ascent. Save ponds and export reports for further exploration. OR SIMPLY ENJOY THE VIEW Choose full-screen observation, gentle activity-inspired sound, or an in-app Screensaver mode that creates a succession of fresh ponds. An accessible field guide explains the controls, visual signals and biological concepts. Tony Crayfish Evolution is an exploratory simulation inspired by biology. Its creatures and ecological rules are simplified models, not predictions of real ecosystems. Unexpected outcomes are part of the discovery.
