CONSEQUENCES

Selected Consequences;
Evolution is True 

MORALITY

Morality

 

"It is sometimes said that science has nothing to do with morality. This is wrong. Science is the search for truth, the effort to understand the world; it involves the rejection of bias, of dogma, of revelation, but not the rejection of morality." ~ Linus Pauling

​

Morality refers to ideas of right and wrong, behaviors that are in accord with standards that are deemed acceptable. The question then arises, what standards and who sets them?  Many people believe that to accept evolution necessarily leads to atheism and no basis for a moral life. However it should be noted that many religious followers endorse evolution, including human evolution. The Pope, leader of the Catholic Church with over a billion followers, accepts evolution. So do many more liberal Christians, most Jews and of course the Biologos apologist evangelicals.  Most of the top scientists and philosophers, some who are theists, at universities around the world accept this all encompassing scientific theory. 

​

Our Moral Compass

 

Is it not apparent that nearly all people have a moral compass? The question then becomes where did it come from? 

Where does this internal sense of morality come from? Numerous studies show it’s innate. Can we look to evidence? Studying nature gives us the answer. Morality evolved in social species including humans and we later refined it culturally.

 

“Morality seems to me to be a natural phenomenon - constrained by the forces of natural selection, rooted in neurobiology, shaped by the local ecology, and modified by cultural developments.”

~  Patricia S Churchland

​

Many people merge evolution into atheism and assume accepting evolution means one can't be moral or can't have a reason to be moral.  See here and here. Ironic that it's not true as detailed by studies

​

How do we know morality evolved? Various studies show it is innate and found in numerous species and shows a progression with more sophisticated social species. Shermer notes:
 

“The following characteristics are shared by humans and other social animals: attachment and bonding, cooperation and mutual aid, sympathy and empathy, direct and indirect reciprocity, altruism and reciprocal altruism, conflict resolution and peace-making, community concern and reputation caring, and awareness of and response to the social rules of the groups. As social primate species we evolved the capacity for positive moral values because they enhance the survival of both family and community. Evolution created these values in us, and religion identified them as important in order to accentuate them.”

~ Shermer, M. The Bart Ehrman Blog. Guest Post. Why Even Conservative Christians Should Accept Evolution. Part 2, Sept. 8, 2022.

 

Frans de Waal notes that fairness arises from reciprocity and empathy from compassion, which exists in many social animals. A famous experiment was done with monkeys involving grapes and cucumbers. This video starting at 12:20 shows the result. Where did that monkey get its feelings of fairness, of what is right and wrong in that situation? The same place you did, with some additional cultural refinement.

This TED talk is actually excellent and very much pertinent to the subject here and I hope you watched all of it. If you have doubts about how the fairness experiment was performed, conditions and controls, I do hope you viewed the entire 16 minute presentation.

Chimpanzees have been noted to perform behaviors that appear to be proto-ritualistic at "shrine trees".

What about Hume's "ought" vs. "is"? Science can't tell us about morals and ethical standards? Or can it?

Conclusions

​

Bottom line - our morality evolved in humans and then we refined it culturally. We have the evidence. It was not imparted into us by another source.  I assert that some moral standards are provisionally absolute, imparted by evolution over millions of years. They are so set in our DNA that they will probably never be changed. Many more morals are subjective and we’ve come up with secular societies that far exceed what other proposed sources have provided to us.

​

This is just another example of how evolution affects about everything in our lives. Understanding of psychology must include evolution as the study of ethology demonstrates that how we behave usually has evolutionary roots. As Pinker has noted, in Medieval times people roasted cats for fun. What changed? Our moral arc was bent by Enlightenment values, not from other proposed sources of authority.

 

Certainly our present laws in the best of our secular democracies have far exceeded alternatives.  The morality of secular humanism, based partly on evolution, exceeds that of alternatives.
