I was going through Bhagavad Gita Chapter 16, Verse 21 which talks about lust, anger and greed (http://www.bhagavad-gita.org/Gita/verse-16-16.html). Thought of checking in internet whether these three are the only ones / anything more as well as what others are talking about because these are related to human in general (may be related to species in general). I came across 2 good webpages (http://en.wikipedia.org/wiki/Seven_deadly_sins, http://www.unification.net/ws/theme052.htm). World Scripture outlined in unification website listed so many similar views from various parts of the world.
Our life seems to be very short to see the evolution of one species to another. I doubt whether the scripts / knowledge humans have now will help anyone in future to identify the evolution of one species to another with hard facts without assumptions. What is next in brain evolution (http://www.solhaam.org/articles/humind.html) and when is it going to happen / is it happening now?
Need to go through articles of http://en.wikipedia.org/wiki/Carl_Sagan to understand more about cosmos.
