Not always, because if you go back far enough we all descend from bacteria.
If you go back a few hundred years, the picture was pretty much the same. The only nations where private individuals left of their own initiative to create population colonies were individualistic ones (English, Scottish, Dutch, Scandinavians, some Germans, a few North French).
The only regions that adopted Protestantism, willingly breaking off with over a millennia of traditions and taking the risk to be at war with the rest of Catholic Europe, were also individualistic ones.
As society, culture and lifestyle (and even languages) have changed tremendously since the Renaissance, I really don't think that individualism is simply acquired through culture or the local environment. It must be genetic, and therefore only changes as fast as the gene pool does. Alleles for individualism can increase or decrease in a population through natural selection, but this takes time (many centuries for a few percent of change... unless there is a cataclysmic event, like plague or a genocide).
