What is GenePool?
It's a computer simulation where hundreds of virtual organisms evolve swimming skills. These organisms are called "swimbots". You can set mate preference criteria and thus influence what the swimbots consider as attractive qualities in potential mates. The most attractive swimbots get chosen most often to have little babies, and so their genetic building blocks propogate to future generations. Eventually, swimbots get better at pursuing each other, competing for food, and becoming babes to other swimbots. Local gene pools emerge which compete for mates and food (for energy to have offspring). Eventually a dominant sub-population takes over.

Sometimes, everyone just dies. That's not a bug. That's nature! If you want, you can move swimbots and food around to help your favorite critters survive.

Gene Pool is best appreciated as a virtual Darwinian aquarium in which you initiate a primordial soup, and then occasionally check up on what Virtual Mother Nature is up to - about every fifteen minutes (or every few days, if you are interested in long-term evolutionary experiments!).

Very Good, Except...

This is an excellent evolution simulator! The only things stopping me from rating this 5 stars is:

1. There is no evolution for a carnivore. They cannot exist in this simulator.

2. There is no landmass that the organisms could potentially evolve to live on. (This is a minor issue)

3. I am sure that many other people would enjoy a photosynthetic/chemosynthetic/radiosynthetic organism, meaning that it would be possible for the swimbots to evolve into a plant-like organism.

4. I have witnessed two members of apparently different species reproduce. Is this a bug or are they really two members of the same species?

The issues I'm having probably cannot be implemented, except for number one. Out of all of these, I think number one would be simplest. If not for these things, my rating would certainly be 5 stars. And I do realize that it is still very early in development, so I do understand. I hope that you do at least add predator/prey relationships or symbiosis relationships, as parisitism. Thank you for (possibly) reading this and (possibly) responding via an update or text.

Amazing app

This amazing teaching tool allows one to truly seen some of the subtleties of natural selection and ecology play out in real time.

This may sound corny but to me as a biology teacher this feels like a piece of literature. The simulation contains within it the potential for so much instruction. It is made the phenomenon of evolution completely clear and understandable to the youngest of my middle school students. I have a 90 students who can completely visualize the process of selection and many of its implications and part thanks to this amazing piece of software. I hope Apple’s continuing development of iOS doesn’t result in great software like this always being broken for no reason other than some small change in OS... and needing to constantly be re developed by developers like this. I really wish there were some kind of structure or support in place to support an archive of things like this to make sure their carry forward but not entirely on the back of the person who created it.

I am so grateful that the developer had the time and resources to repair this is now functioning fully!

With a little help from...

Enjoyable for an all herbivore evolution simulation. I have seen too many first generation creatures demonstrate advanced directional mobility . Maybe they had big brains to start or maybe they got a little help from their designer friends from above. At the same time, the long straight worms with superior swimming efficiency are condemned to cluster in the corners stupidly helpless.
So the same kind of structure always wins.
What's fun is how much you care for these things. And it's cleverly designed to let you bring your favorites food, move competitors away, etc. and tweaking the environmental conditions can have amazing consequences. Overall a beautiful 2d pond.
