It was probably such in-group collaboration and generosity combined with amazing inter-group hostility and ignorance which got us out of Africa to successfully conquer the world. Now, you'd think we have grown beyond it. Culture (or, if you want, education!) is, by and large, about suppressing or re-directing our biological urges and limitations and arguably one of the major things which separates us from animals.
Sadly we still have a lot of work to do. It is a fact that we in the West care less for a life in Afrika than one in Paris. Just note the difference in scale of what I'm just saying here: pure in terms of human lives, Paris is barely a blip on the radar compared to all of Afrika! But, just like a robbery around the corner of your street is bigger news than the massacre of thousands would be in Nigeria, we care most about what is close.
That is not to say it is all bad news. People can be taught to consider a wider range of people to be their in group. See Europe, for one, I strongly feel European and the attack on Paris is almost as personal as if it were in the Netherlands. Then again, I live in Germany and have lots of friends all over Europe so cross-country identification comes a bit easier by now ;-)
Skypointer: "The California Nebula (NGC 1499) is an emission nebula located in the constellation Perseus. It was discovered by E. E. Barnard in 1884 and is named after the U.S. State of California because it appears to resemble its outline on long exposure photographs. It is almost 2.5° long on the sky and, because of its very low surface brightness, it is extremely difficult to observe visually. It lies at a distance of about 1’000 light years from Earth. Its fluorescence is due to excitation of the Hβ line in the nebula by the nearby prodigiously energetic O7 star, Menkib (xi Persei)."
"Photographing a Hydrogen emission nebula with a unmodified DSLR camera from a light polluted suburban backyard means you are either clueless, desperate or looking for a real challenge, as the sensitivity of the camera to this wavelength is very low, due to the factory installed IR filter in front of the chip."
"I decided to give the challenge a try. While finding the Nebula with a modern computer-guided telescope is no big feat, framing the shot was. On my raw files the nebula was mere ghost and while I thought I saw some fuzzy red stuff in the right position I was not sure that I got it right until I processed the stacked frames the other day on my computer."
"After sitting next to my telescope for more than an hour with temperatures in the 40ies (5-10°C), I decided to get some sleep and let the auto guider do its job on its own. As there was some fog forecasted for the morning I set my alarm clock for 1:30 a.m. to check if everything was running fine. When I got up there was a thick fog billowing in my backyard and my equipment was soaking wet, while my camera dutifully shot white frames and the auto guider was complaining bitterly that it had lost its guide star."
"After rubbing down and stowing my equipment I finally was back in bed at 2:30 a.m."

The spikes on the stars were added during post processing, as a refractor of course does not cause such an effect.
