Evolution Simulation Software

[Edgar Valencia]

Hi Guys

I wonder if anybody knows about a free software to simulate evolution,
speciation, extintion and things like that and from where can it be
downloaded. I need it for teaching evolution to a Bs Sc group and I've
always thought that is much more funny to watch at least the plots of
the equations we're talking about
TIA
Edgar.
PS I work with Mac's so I guess that reduces my options right? :(
