Natural selection is based on three basic facts:* living organisms produce more offspring than in needed to maintain the population.
- there is hereditable variation among members of a species.
- there are limited resources of food, space, etc. for any species.
Given the overproduction of new organisms and limited resources, then there will not be enough resources for all individuals. Hence there is competition for resources. Given the hereditable variations, some individuals will do better in the competition for resources than others. Those individuals which do better in the competition for resources will tend to have more offspring in the next generation. The increase in offspring will increase the proportion of those advantageous hereditable variations in the population. That results in a change in the proportions of different alleles in the population. That is how natural selection drives evolution.

That is about as honest as I have seen but it arises from an essay of overpopulation and resources driving the justification for invasion ( not evolution) transfered to biological evolution.You call it the ‘fact of natural selection’ and indeed many stupid Christians beg questions from that empirical ‘fact’ but it all amounts to the disgusting transfer of an essay on human supremacy on to creation and biological evolution -
“An Alaric, an Attila, or a Zingis Khan, and the chiefs around them, might fight for glory, for the fame of extensive conquests, but the true cause that set in motion the great tide of northern emigration, and that continued to propel it till it rolled at different periods against China, Persia, italy, and even Egypt, was a scarcity of food, a population extended beyond the means of supporting it.” Thomas Malthus
“Without consideration of traditions and prejudices, Germany must find the courage to gather our people and their strength for an advance along the road that will lead this people from its present restricted living space to new land and soil, and hence also free it from the danger of vanishing from the earth or of serving others as a slave nation. The National Socialist Movement must strive to eliminate the disproportion between our population and our area—viewing this latter as a source of food as well as a basis for power politics—between our historical past and the hopelessness of our present impotence” Hitler
“One day something brought to my recollection Malthus’s “Principles of Population,” which I had read about twelve years before. I thought of his clear exposition of “the positive checks to increase”—disease, accidents, war, and famine—which keep down the population of savage races to so much lower an average than that of civilized peoples. It then occurred to me that these causes or their equivalents are continually acting in the case of animals also… .” Charles Darwin
The idea of betrayal for 30 pieces of silver comes to mind and this only refers to the anti-scientific empirical approach.A Church that does not actively fight the root cause of this problem ,and Darwin is merely a symptom,hardly represents the Church of Christ.The trajectory of a supremacy ‘cause’ is so obvious and so explicit that those who even consider carrying on discussing the matter as the empiricists would have it are as bad as the non believing empiricists themselves.
