Add a new line, following the second line, to the rule Apes, with this text:

Each Ape has an Attractiveness, which defaults to 2 and is tracked in the GNDT under a column named “ATR”. It can be referred to by the shorthand ATR. ATR can be negative.

Change the text of what happens during a New Generation Event to the following:

1. Add the ATR of each Ape to their food.
2. 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.
3. For the Genetics in the sentence starting with “The default Genetics is the one noted as”, change the first through the fifth Gene by setting it to a Gene randomly (but not necessarily in the GNDT) chosen from the corresponding Genes of A and B.
4. For each Ape, set their gender, food, LA, Genetics, and ATR to default.
5. For each Ape, roll a DICE4. If a 1 is rolled for them there, that Ape Mutates.
6. For each Tradition in the Culture whose Complexity is higher than the Intellect of every Ape, remove that Tradition from the Culture.

Change the list of Genes and their effects to the following:

*Nothing: This Gene does nothing.
*Speed: Directly after a New Generation Event, increase LA by 1.
*Deformed: Directly after a New Generation Event, decrease LA by 1. If this would cause LA to be less than 1, set it to 1.
*Smell: Gain an additional Food when performing the Forage action.
*Brawn: This Gene is involved in the Hunt action.
*Intelligence: This Gene is involved in the Intellect rules.

Change the description of the Hunt action to the following:

Hunt: Roll DICEX, where X is 3+(the number of Br genes this Ape has) - Gain one less Food than the result.
