Civolution

Yes — you may displace a tribe when migrating into an occupied territory: the displaced tribe is placed into the wilderness (keeps its current upright/lying state) and your migrating tribe takes the vacated encampment but must be laid down (weakened). (Rulebook p15)

You pick the column (or must use the existing column for that card type), the card is installed in the lowest free stage and only the leftmost cost spaces for that stage are active; you must fulfill all active cost spaces by returning materials or meeting feature requirements, then gain any success points and instant bonus before inserting the card. (Rulebook pp24–25)

When you take an income chip you immediately install it and perform its action once; thereafter the chip remains in your stage partition, its action automatically triggers each Income phase, and you can also use a separate key action to perform one of your income-chip actions (or take 1 success point instead). (Rulebook p23)

Each encampment or boat tribe costs 1 food and each wilderness tribe costs 2 (farms make encampment tribes automatically fed and reduce wilderness cost to 1); any tribe you don’t feed is weakened (strong → laid down) or dies (weak → returned to your supply), and you may use the Deus ex machina special action to save a dying tribe by moving your Favor disc back one step. (Rulebook p33)

You roll all your fate dice and pass depending on how far your disc is on the Favor of Agera track (higher spaces allow more successful faces or auto-pass on the rightmost); you may spend idea markers to increase or decrease a fate die’s value by one per marker before resolving the test. (Rulebook p17)

Each category has a defined unit: Technology (and other progress tracks) scores by multiplying your disc’s space on that progress track by the category points, Evolution scores by multiplying your total feature markers by the points, and Expansion scores by multiplying the number of territories where you have at least one tribe by the points; final scoring proceeds through each category as described and determines the starting civilization for the next era.
