There is an interesting footnote we could discuss, when speaking of culture, since the topic is still active.
Indian and Punjabi/Sindhi/Bangla muslims and Indian Hindus are essentially from the same stock.
I guess historically no one denies that these all moved down as one over thousands of years, predominantly as Hindus.
Yet today we see that not just culturally, but even in terms of mindset and psyche, these two exhibit significantly different patterns.
What could have influenced this sub-evolutionary pattern?
Do we see such a phenomenon anywhere else in the world as well?
Are there trends that emerge? Any similarities between diverse cohorts?
If one wants to understand the evolution of cultures and influence on one another, he/she has to study demographic processes like immigration, emigration, natural growth rate, distribution based on income, religion etc.
Communication among the people living in nearby and distant places.
Industrialization, education structured of other religion or region comes into important factor.
Now one has to understand the time period and intensity of influence.
So in terms of mindset and psyche, one has to see the change over decades and generation wise.
For example: the culture followed by current generation is different from the previous generation even when there was no conversion or change in family structure. The parents of certain people who lived in villages and their kids born in cities, the communication and information they are exposed through TV, interne, mobile phones etc. Whether it comes to worship, view about elders, nation, festivals etc.
I haven't touched the other factors still you can determine impact of these factors.
