The speciation autofork

<< < (2/2)

EricL:
A couple more points:

It takes a while for the ancestor information to accumulate.  If you try this on an old sim from an older version, the graphs and such won't be correct until the sim runs for awhile since the ancestor data wasn't maintained by releases older than 2.43.1M.

There's an issue with long-lived big berthas.  If a bot mutates or something such that it lives a long long time relative to it's relatives/offspring, it can get forked by itself into it's own species.  If you see new species getting created with only a single member, this is probably what is happening.

I bet one may see that a lot in a new evosim, where bots can float around doing nothing for 30 M cycles just mutating. Maybe setting the sliders high in such a case might be a good idea?

Right.  Early in an evosim, or in any sim for that matter, every bot is essentially it's own species since there is no Most Recent Common Ancestor.   Until you have a functioning sim I.e. one where bots are reproducing and there is selection pressure and differential survival tied to genetics, the whole concept of species doesn't really apply.
