BioLogos promotes “evolutionary creation,” the view that all the lifeforms on earth came about by the God-ordained process of evolution with common descent. The word evolution can be used in many ways, but in biology, it means descent with modification. In other words, small modifications occur at the genetic level (i.e. in DNA) when a new generation descends from its parents. Over many generations these modifications can result in significant differences from the ancestral population. When those differences are beneficial for survival, they can work their way through a whole population of organisms, and if the differences are substantial enough, scientists may recognize those organisms as a different species from their ancestors.
