This is kind of a sister proposal to Hunting, but I suppose it is conceptually distinct enough to warrant its own proposal.  I know that neither this nor Hunting seems particularly powerful on its own, and that Brain Size is still missing, but I intend to propose the final piece of the puzzle if these go through.

Replace the following text in Evolutionary Currency:

Occasionally, every lifeform may increase eir DNA Points by 0.05 * Z, rounded down, where Z is the number of DNA points currently possessed by said lifeform. No lifeform may receive more than 50 DNA points per week this way.

with

Occasionally, every Lifeform may Reproduce.  This results in the Lifeform gaining 0.01*the Lifeform’s Unique Ability*Z, rounded down, where Z is the number of DNA points currently possessed by the Lifeform.  No Lifeform may receive more than 10*the Lifeform’s Unique Ability DNA points per week this way.
