Replace “an Ape who does not have less food than another Ape is “Well Fed”.” with:-

An Ape who does not have less Food than another Ape of the same gender is “Well-Fed”.

Replace “Choose two Apes that have the most food. If there are 3 or more tied, randomly choose 2 Apes from that set. For the rest of this action the Genetics of the chosen Apes in this step are labeled A and B, one for each Ape.” with:

If it is possible to do so: randomly select an Ape from the Well-Fed male Apes, then randomly select an Ape from the Well-Fed female Apes. If two Apes are chosen in this way, then they are the Progenitors for this Generation Event.

Replace “the corresponding Genes of A and B.” with:

the corresponding Genes of this Event’s Progenitors. (If there are no Progenitors for this Event, then instead every Ape’s Genetics are set to the default Genetics.)
