Simple definition of culture contains the beliefs, customs, arts, etc., of a particular society, group, place, or time . So culture contains the collective story, why we do what we do. I think the collective story is at first in between the group, invisible yet potent and powerful. You can see the powerful side in anything that man has produced from pyramids of Giza to Hollywood movies. Culture is invisible force that shapes the visible world.
In a bigger scale, culture has been huge advantage. By changing story, so through cultural evolution, groups of people have been able to quickly cope and change the course of their collective efforts, without relying on the slower biological evolution.
Time and surrounding world are important building blocks for the culture. Sudden changes in environment will inevitably call upon a need for change in the way of doing things.
About biological evolution Darwin famously said that “It Is Not the Strongest of the Species that Survives But the Most Adaptable”. In cultural context we can say that it’s not the strongest of cultures that survive, but the most adaptable, those who learn the quickest.
Learning needs to be based on truth, seeing the reality as it is, instead of some biases. Here is where scientific method comes really useful. Then continuing further to apply the learning attitude and the scientific method to seek solutions to our common problems? Science has already done a lot of work to uncover the similarities of life and the universe. What we need to do now is to adapt some of what we’ve learned into action and forge that into a culture of action to find solutions.
P.S. More about the connections and similarities of life in an awesome video by RSA ANIMATE: The Power of Networks.
