Natural selection is the process by which individual organisms with favorable traits are more likely to survive and reproduce. Natural selection is one of the cornerstones of modern biology. The term was introduced by Charles Darwin in his groundbreaking 1859 book The Origin of Species. (Wikipedia)
I was taught, from an early age, by our secular educators, that Charles Darwin was right, we evolved. In the teaching of natural selection, the weaker link in any species, was eventually eliminated from the gene pool by virtue of the fact that they could not compete in strength or intelligence.
If evolution is true and it is a benefit to have the weaker of a species eliminated, why then do we post 15 MPH speed zones around our high schools? By the age of 14 to 18, wouldn't one think that a youth should know how to cross the street with the light and in a crosswalk? If not, should they be allowed to procreate?
