These thoughtless, heartless "organisms" evolve the inclination to save their siblings over their cousins. Press SPACE to hide/show lists. Hiding them will improve speed. Showing them give you a glimpse under the covers. -------------------------------------------------------------------------- Kin selection is the evolutionary strategy that favours the reproductive success of an organism's relatives, even at a cost to the organism's own survival and reproduction. If you share half of your genes with your sibling but only one eighth of your genes with your cousin, then theoretically you should be much more inclined to save your sibling than your cousin. This project attempts to demonstrate the principal by doing the following: 1) 500 children are generated. Each child has two randomly generated attributes representing the chance of saving a sibling and the chance of saving a cousin. Each attribute is represented by a 6 bit number. 2) Each child is put in peril. Each sibling and cousin will be given a chance to rescue them according to their proclivity. If a sibling or cousin decides to save them, there is a <CHANCE OF PERISHING DURING RESCUE> chance that they will die. If any sibling or cousin does not perish when attempting rescue then the child will live. 3) The survivors are randomly mated generating a total of 500 children. The attributes of the parents are combined randomly to generate the child's attributes. 4) The children are then put in peril as in step 2 and then mated as in step 3, etc etc. This process continues down through the generations..
What you should see: At the start the average chance of altruism towards a sibling or a cousin should be about 50% for each, as they were generated randomly. As time goes on you should see the average altruism towards cousins drop while altruism towards siblings rises. By dropping the CHANCE OF PERISHING DURING RESCUE to something very small you can get a more precise (and possibly different) result, but it will take longer to develop. I've noticed that on average the population is 8-16 times more likely to save a sibling vs a cousin. This all happens by chance. These thoughtless, heartless "organisms" are inclined to save their siblings over their cousins.
