The legacy of the ancestors: how did they program our brain?

Evolution has come a long way. Humanity has a huge cultural baggage, but our appearance has not undergone significant changes, if we talk about the first representatives of the human erectus. The brain also did not change dramatically. We live in the modern world, we go to work, we live in cultural life. But what oddities in our behavior today do scientists explain with the peculiar legacy of our ancestors? Let us try to figure it out.

Many centuries ago, if our ancestors had the opportunity to eat - they ate as much as they could, and did not leave it for later.

The brain simply cannot accept the fact that we have food in free access and seeks to obtain this information after seeing it. Our consciousness just needs to make sure that everything is in order and tomorrow we will have something to eat.

Then it served as a protective function of the body - at the time of danger, an extremely fast reaction was needed.
