How does &quot;be altruist to those who are similar to you&quot; evolve?

Altruism that is


Not reciprocal
Not familiar


has little explanation. One possible explanation is that the trait itself may correlate well with genetics. One great answer there is that often the cost of altruism is small anyway. It can explain why people vote. Here the expense is small anyway.

Still there seems to be some factors that are even bigger.

Let's take a look at people that die for their ideology. Christian martyrs, Muslim suicide bombers, or Communist guerilla fighters. They seem to get so little and well, die.

And that's pretty common. It seems pretty easy for a leader or pedagogue to rouse men to be soldiers. Of course, becoming a soldier is a pretty shitty job, yet most men don't mind.

These people make a huge sacrifice for the sake of their country, ideology, or people that are not even genetically related to them.

Why?


Question: How do I import an iPhoto library into Lightroom, keeping adjustments intact?
Answer: This is actually the expected behavior of the plugin.  To quote from Adobe's blog article on the importer for Aperture/iPhoto (bold emphasis is mine):


  Information that is not imported into Lightroom:
  
  
  Image adjustments
  Smart Albums
  Face Tag Region of Interest (face naming tags are mapped to keywords)
  Color Labels (other than optionally as keywords)
  Stacks (other than optionally as keywords)
  Any kind of creation (books, web galleries, etc) other than the collections that correspond to them
  


Given that both Lightroom and Aperture/iPhoto basically use proprietary metrics to perform adjustments, it would be pretty difficult to find a way to equate the two types of adjustments, and they probably wouldn't be exact matches, anyway.
