  • altruistic
  • I am not familiar enough with studies of "altruistic" behavior to know whether the term "altruism" in such contexts is normally used to mean something more like cooperation , but I have always disliked the term. (blogspot.com)
  • reciprocal
  • There are reports that vampire bats regurgitate blood to other individuals in the colony to whom they're unrelated, but those need confirmation, and there may also be reciprocal altruism, so that individuals regurgitate blood to those from whom, one day, they expect a return meal.

  • selfishness
  • It is to group selection we must turn to investigate the origin of moral traits, since morals (such as altruism) concern how we treat others, and especially how we moderate our selfishness in the service of larger groups. (blogspot.com)
  • I'd just say that using our reason to compare altruism against selfishness, deciding which way is the best and acting on our soundest judgment is the "natural' way for man to live. (blogspot.com)
  • notion
  • I found the following two points, taken together, interesting in light of a notion I have seen bandied about to the effect that altruism exists in nature or has somehow been selected for. (blogspot.com)
  • among
  • Nevertheless, the use of the ethical term fosters misunderstanding of such work (not the least because of the actual meaning of altruism) among non-scientists in the general public. (blogspot.com)
  • Behavior
  • To make it even simpler, altruism is a behavior that opposes egoism, and is generally understood to be an act that benefits others at a personal cost. (studymoose.com)
  • But altruism is a behavior present also in our own species and, luckily, it is worldwide spread. (studymoose.com)
  • gene
  • The problem has always been figuring out in quantitative population genetics terms whether this made any sense, especially how a strategy of altruism could survive against cheating from within the group as well as from gene dilution from outside sources. (blogspot.com)
  • is mathematical, creating a model of small populations with given amounts of gene flow from outside (or, conversely, inbreeding), given amounts of warfare in which groups extinguish other groups and expand accordingly, and given amounts of altruism, expressed as individual costs (death in warfare by warriors) and group benefits (success in warfare).

  • individual
  • Then the paper draws on various other sources to decide on reasonable bounds for these various values, plugs them in, and comes up with the finding that altruism in these simplified terms could be selected for, even at substantial individual cost. (blogspot.com)
  • The equality represents the boundary case, where increased c, the individual cost of altruism, breaks even versus its group benefits. (blogspot.com)
