If you mean, "Does belief in the Theory of Evolution affect the way a country is run or what Laws are (or are not) introduced?" then yeah, in my opinion it does. Racism for example used to be a HUGE problem back when people believed that Black folk were not as highly evolved from the monkey as White folk, and were in fact, sub-human.
Chimpanzee who are our closest relatives... Are white... They just have black hair. Just saying if you are going by skin colour white people are closer in tone than our nearest relative. Actually the argument used was "white man's burden" the Genetic thing was a recent one on behalf of crazy right wing idiots.
This all ties in with the Slave Trade as well. In the 1800s the Australian Aboriginies were highly persecuted, chased, shot, and displayed in museums, as sub-human "missing links".
Mainly because they were interesting. And the Theory of Evolution was not in place.
Presumeably this was all perfectly legal, because the Theory of Evolution dictated that these people were not really human, and therefore did not have human rights. The problem of racism also falls under the last question about moral consequences. Many other laws have also been passed that greatly oppose Christian and other moral teaching, and I believe that these can be linked with the general embracing attitude towards the Theory of Evolution.
STOP! Its Hammer Time... DARWIN STYLE!
"I have watched how steadily the general feeling, as shown at elections, has been rising against Slavery. What a proud thing for England, if she is the first European nation which utterly abolish is it. I was told before leaving England, that after living in slave countries: all my options would be altered; the only alteration I am aware of is forming a much higher estimate of the Negros character. It is impossible to see a negro & not feel kindly toward him; such cheerful, open honest expressions & such fine muscular bodies; I never saw any of the diminutive Portuguese with their murderous countenances, without almost wishing for Brazil to follow the example of Haiti; & considering the enormous healthy looking black population, it will be wonderful if at some future day it does not take place." - Charles Darwin (to Catherine Darwin via letter...)
"A few days afterwards I saw another troop of these banditti-like soldiers start on an expedition against a tribe of Indians at the small Salinas, who had been betrayed by a prisoner cacique...Two hundred soldiers were sent; and they first discovered the Indians by a cloud of dust from their horses' feet, as they chanced to be travelling...The Indians, men, women, and children, were about one hundred and ten in number, and they were nearly all taken or killed, for the soldiers sabre every man. The Indians are now so terrified that they offer no resistance in a body, but each flies, neglecting even his wife and children; but when overtaken, like wild animals, they fight against any number to the last moment. One dying Indian seized with his teeth the thumb of his adversary, and allowed his own eye to be forced out sooner than relinquish his hold. Another, who was wounded, feigned death, keeping a knife ready to strike one more fatal blow. My informer said, when he was pursuing an Indian, the man cried out for mercy, at the same time that he was covertly loosing the bolas from his waist, meaning to whirl it round his head and so strike his pursuer. "I however struck him with my sabre to the ground, and then got off my horse, and cut his throat with my knife." This is a dark picture; but how much more shocking is the unquestionable fact, that all the women who appear above twenty years old are massacred in cold blood! When I exclaimed that this appeared rather inhuman. he answered, "Why, what can be done? they breed so!"
Every one here is fully convinced that this is the most just war, because it is against barbarians. Who would believe in this age that such atrocities could be committed in a Christian civilized country?" - Charles Darwin, Voyage of the Beagle
"Great God how I should like to see the greatest curse on Earth Slavery abolished." - Charles Darwin to Asa Gray (correspondence)
So technically those things would have and did shock the father of evolution. Who indeed was proud that the UK had banned slavery. And he himself said that black people and white people came from the same source if you believed in the theory of evolution from "lesser" organisms. It was the religious who claimed that they were inhuman at the time. Not the evolutionist.
