why we should let natural selection take its course

The phrase “let nature take its course” is so widely used and accepted, it has gained idiom status. The idea that nature is self-perpetuating and self-correcting is an attractive one. The supporting evidence is strong too – I mean, look at how long nature thrived before humans were even a species!

What Is Natural Selection?

• Organisms that are unable to adapt to changes in the environment are unlikely to survive or reproduce.
• Those that can adapt are much more likely not just to survive, but also to thrive and reproduce.
• As offspring are born, they will have the advantageous genetic traits passed on from their parents.
• As a result, the species will change over time.
• Why? ...

What is the significance of natural selection?

The five principles of natural selection are typically described as follows:

1. Most characteristics in the population must be inherited.
2. More offspring must be produced than can survive.
3. The fittest offspring must be more likely to survive and reproduce.
4. There must be genetic variation that allows for the best traits to be selected.
5. There must be sufficient time for reproduction to occur and evolution to take place.

I’ve often wondered what it would be like to win the lottery and suddenly have more money than I could ever reasonably spend. I won’t win because I don’t play, but of course most people who play don’t win, either.

The Price of Motivation

By way of example, consider two hypothetical ancestors, Thag and Crag. During the Pleistocene, each of them lives the dream and single-handedly kills a mastodon. As expected, both are incredibly happy and the toast of their respective clans.

Age, Health and Happiness

Studies show that older people tend to remember the positive things in life rather than the negative things, while younger people remember the positive and negative equally well. The predominant psychological theory to explain this is that older people are aware of their limited time left, so they prioritize positive emotional experiences.

Puppies and Plane Crashes

The hypothesis was later tested by a Ph.D. student of mine named Elise Kalokerinos. Over the course of a year in a lab, she showed young and old adults photographs of nice things, such as baskets of puppies, and of nasty things, such as plane crashes. She then tested their memory of the images.

Take the Good With the Bad

So what is the purpose of happiness? As you can see, there is no single answer. Happiness motivates us to do things that help us survive and reproduce, and it helps keep us healthy. But happiness is not an end in and of itself.
