To get more insights into who you are for example. The first step is to realize that a lot of what went on in the last few thousand years is wired into us.

Lamarckian evolution. Truly cutting edge crap you're peddling.

Different stuff went on with different ethnic groups in different regions, so it does make a difference which one(s) you look at.

Before the industrial revolution, the vast masses who constituted agricultural societies lived virtually identical lives: illiteracy, superstition, abject poverty, and a constant struggle for survival against the elements, disease and the wars of the more powerful.

But if all you do is work like a drone for 5 days, let out your stress for two, and then repeat, then I'll grant you that it doesn't much matter. But if you ever have more choices in life and more time time to reflect, then this ancestry stuff might get more interesting.

more interesting but no more plausible!
